I Missed Flutter's debugPrint After Moving to Kotlin

Cahyanudien Aziz Saputra — Fri, 02 Oct 2026 16:35:56 +0000

For more than three years, Flutter was my main environment for building applications.

Recently, I started working on several new projects with Kotlin and Jetpack Compose.

There was no dramatic problem.

Kotlin was fine. Android's tooling was fine. And Android already had a perfectly capable logging API.

But there was one small thing that kept bothering me.

Logging felt unnecessarily repetitive.

In Flutter, I could simply write:

debugPrint('User loaded: $user');

In Kotlin, the equivalent usually looks more like:

Log.d("MainActivity", "User loaded: $user")

Of course, this is not a serious problem.

It's a few extra characters.

But when you write something dozens or hundreds of times during development, these tiny decisions start becoming part of your workflow.

I kept thinking:

I don't need another logging framework. I just want the convenience I was used to.

So I built one.

GitHub: https://github.com/cas8398/debugprint

Maven Central: https://central.sonatype.com/artifact/com.flagodna/debugprint

Not another logging framework

The first mistake would have been trying to build a "better Android logging framework."

I wasn't interested in that.

Android already has Logcat, and there are plenty of mature logging libraries for applications that need structured logging, persistence, remote logging, crash reporting, or sophisticated filtering.

That wasn't the problem I was trying to solve.

I wanted something much smaller:

debugPrint.d("Loading user...")

That's it.

A tiny convenience layer for development-time logging.

That became debugprint.

The basic idea

The API is intentionally close to the mental model I had from Flutter.

debugPrint.d("Hello")
debugPrint.i("User signed in")
debugPrint.w("Cache miss")
debugPrint.e("Request failed")
debugPrint.v("Verbose information")

Custom tags are still possible when I actually care about them:

debugPrint.d("Auth", "Token expired")
debugPrint.e("Database", "Query failed")

The library is not trying to hide Android's logging system.

It simply removes some of the repetitive parts that I don't always need while developing.

Debug means debug

One thing I wanted from the beginning was for the library to behave like its name suggests.

If I'm using it for development debugging, I don't want to manually write this everywhere:

if (BuildConfig.DEBUG) {
    Log.d(...)
}

So debugprint automatically enables logging for debug builds and disables it for release builds.

The intended workflow is simply:

Debug build   → logging enabled
Release build → logging disabled

No initialization call.

No Application setup.

No configuration boilerplate.

Add the dependency and use it.

implementation("com.flagodna:debugprint:0.1.1")

The package is available on Maven Central:

https://central.sonatype.com/artifact/com.flagodna/debugprint

Automatic caller information

Another thing I found repetitive was tags.

When debugging something locally, I often don't really care about creating a meaningful logging category for every single message.

I mostly care about:

Where did this message come from?

So debugprint can derive the tag from the caller.

Instead of:

Log.d("SomeClass", "Loading...")

you can simply write:

debugPrint.d("Loading...")

and get caller information such as:

SomeClass.someFunction:42

There is an obvious trade-off here.

Finding the caller requires inspecting the stack, and stack walking is not free.

So automatic tagging can be disabled when necessary:

DebugPrint.autoTag = false

And when I already know the tag:

debugPrint.d("Database", "Loaded 120 records")

there is no reason to pay for automatic caller detection.

Lazy messages

This was probably one of the more important design decisions.

Consider:

debugPrint.d("User: $user")

The message has to be constructed before the logging function receives it.

That may be completely fine for a small string.

But sometimes the value you're formatting is expensive.

So debugprint also accepts a lambda:

debugPrint.d {
    "User: ${expensiveOperation()}"
}

When debug logging is disabled, the lambda is not evaluated.

That means the work required to construct the message can be skipped entirely.

The API stays simple, but it gives me a way to avoid unnecessary work when logging is turned off.

A small sink abstraction

At first, everything simply went to Android's Logcat.

But I didn't want the implementation to be permanently tied to one output.

So the library has a small sink abstraction.

Conceptually:

debugPrint
    ↓
  sink
    ↓
 Logcat

The sink can be replaced with a custom implementation.

That could be useful for something like writing development logs to a file or forwarding them somewhere else.

The important part for me is that the core API doesn't have to change.

debugPrint.d("hello")

can remain the same even if the destination changes.

Logging should not break the app

There is one more rule I wanted to keep:

A logging failure should never become an application failure.

If a custom sink throws an exception, debugprint treats that as a logging problem rather than an application problem.

In other words:

logging fails
     ↓
application continues

A debug utility should not be capable of taking down the application it is helping me inspect.

What I deliberately did not build

There are many things I could have added.

Timestamps.

Colors.

JSON formatting.

Log persistence.

Remote logging.

Crash reporting.

Network transport.

Analytics.

A configuration dashboard.

And probably another hundred "useful" features.

I intentionally left them out.

The point of debugprint is not to become a complete logging ecosystem.

It is supposed to stay small.

If I need a production logging system, I should use a production logging system.

If I just want to write:

debugPrint.d("Why is this null?")

I want that to be easy.

Why make it a public library?

Honestly, the original motivation was personal.

I was working on several Kotlin projects and wanted the same small convenience in all of them.

So initially, this could have remained a private utility inside one project.

Instead, I decided to turn it into my first published Kotlin/Android library and put it on Maven Central.

That made the project slightly more interesting.

Once something becomes a reusable library, even a tiny one, you have to think about API design differently.

You start asking:

Is this API actually understandable?
Is the default behavior sensible?
What should happen in release builds?
What are the performance trade-offs?
How much configuration is enough?
What should never be part of the public API?
Can I keep the dependency footprint small?

A utility that took a short time to write becomes a small exercise in software design.

Is this something everyone needs?

No.

And I think that's worth saying explicitly.

Android already provides logging.

Logcat is not missing.

There are already many mature logging libraries.

debugprint is not trying to replace them.

This library exists because I spent more than three years using one development workflow, moved to another ecosystem, and realized that I missed one tiny piece of that workflow.

That's a very small reason to create a library.

But sometimes small reasons are enough.

For me, the interesting part wasn't inventing a new logging technology.

It was noticing how much developer experience is made up of tiny conveniences that become invisible once you use them every day.

After years of writing Flutter code, debugPrint() had become one of those conveniences.

So I brought the idea with me.

Flutter
  ↓
debugPrint()
  ↓
years of muscle memory
  ↓
Kotlin
  ↓
"Why am I writing this tag again?"
  ↓
debugprint

My first Kotlin/Android library probably isn't going to change how people log on Android.

It wasn't supposed to.

I just wanted my new Kotlin projects to feel a little more familiar.

Introducing the FlagoDNA Roadmap: Building in Public with Purpose

Cahyanudien Aziz Saputra — Sat, 19 Sep 2026 06:58:44 +0000

Today, I published the FlagoDNA Roadmap.

This roadmap is created as a way to share the direction of FlagoDNA more openly — what we are building, what we are improving, and what ideas we are exploring for the future.

FlagoDNA has always been built around a simple idea: technology should respect people.

That means building software with a focus on privacy, simplicity, and long-term independence. No unnecessary tracking. No attention-driven design. Just tools that are useful and respectful.

Why a roadmap?

As FlagoDNA grows, more people are using its applications across different needs — from daily Muslim utilities to productivity and small business tools.

A roadmap helps users understand:

What projects are currently being developed
What improvements are coming next
What ideas are still being explored

It is also a way for me, as an independent developer, to stay accountable to the direction of the ecosystem.

How the roadmap works

The roadmap is divided into three stages:

Now
Projects and improvements currently being worked on.

Next
Planned projects and updates that are being prepared.

Later
Long-term ideas that may be explored when the time and resources are right.

The roadmap is not a fixed promise or a strict schedule. Development priorities can change based on user feedback, technical considerations, and available capacity.

Current Focus

Some of the current areas of development include:

HadisKu improvements with the next beta updates
KasirCepat feature expansion
Future exploration of projects like Muslim Launcher and Tiketea

Each project has its own journey, and the goal is to continue improving them step by step.

Building Slowly, Building Meaningfully

FlagoDNA is built independently, which means progress may sometimes be slower compared to larger companies with bigger teams.

But independence also allows us to focus on what matters:

Creating software that is simple, privacy-conscious, and built with respect for users.

The roadmap is one small step toward making that journey more visible.

You can view the FlagoDNA Roadmap here:

Thank you to everyone who uses, supports, and follows the development of FlagoDNA.

I Built Lens Browser Because the Internet Never Forgets

Cahyanudien Aziz Saputra — Tue, 08 Sep 2026 07:45:25 +0000

Every time we open a website, something happens behind the screen.

A request is sent.

A connection is created.

Scripts are loaded.

Trackers start working.

And quietly, information about us begins to leave.

Most people never see it.

They simply open a page, search for something, read an article, or watch a video — while invisible systems collect signals about their behavior.

The modern internet is powerful.

But that power often comes with a hidden cost.

Our data.

Your Data Is Not Free

Browsing history.

Interests.

Device information.

Location signals.

Online behavior.

These things have value.

Companies build products around this data. Advertisers use it to understand people. Analytics systems use it to measure behavior.

But the question is:

Do we really know how much of ourselves we give away every day?

Privacy should not be something only available to people who understand complicated settings.

It should be the default.

That is why I started building Lens Browser.

Not Another Browser

There are already many browsers.

Some are fast.

Some have beautiful interfaces.

Some have millions of users.

I did not build Lens Browser because the world needed another browser.

I built it because I wanted a browser that starts from a different idea:

The user should be in control.

A browser should be a window to the internet.

Not a tool that quietly watches the person looking through that window.

Privacy by Default

Lens Browser was designed around a simple principle:

Browse privately. No compromise.

It includes:

Dual-layer ad blocking using connection-level filtering and JavaScript interception
Anti-fingerprinting protection through Privacy Mode
Automatic deletion of history, cookies, and cached data when closing the app
Threat detection before dangerous pages fully load
Trusted and blocked domain management
Lightweight design with no account required

No sign-up.

No profile.

No unnecessary tracking.

Just open and browse.

Built Small, Built Carefully

Lens Browser is built with modern Android technology:

Kotlin
Jetpack Compose
MVVM architecture
Android WebView with custom privacy layers

The app is lightweight, around 10 MB, and supports Android 6.0+.

It is also open source under the MIT License.

I believe privacy tools should be transparent.

People should be able to understand what they use.

The Internet Was Built to Connect People

Technology should make life better.

It should help people discover, communicate, and create.

But as the internet evolves, we should not forget one important thing:

Behind every device is a person.

Not a data point.

Not a profile.

Not a target.

A person.

Lens Browser is my small contribution toward a more private internet.

A reminder that privacy still matters.

Lens Browser is available for Android.

Rebuilding MTA ONE v4: Why I Simplified an App That Already Worked

Cahyanudien Aziz Saputra — Tue, 25 Aug 2026 06:04:31 +0000

Sometimes, rebuilding an application is not because the old version is broken.

Sometimes, it is because the application has become too complicated.

MTA ONE was already working. Users could watch MTA TV, listen to online radio, read weekly brochures, and access several other features.

But after years of development, I started to realize something:

The application was trying to become too many things at once.

And as a solo developer, maintaining everything with the same quality was becoming harder.

That is why I decided to rebuild MTA ONE version 4.

Not by adding more features.

But by simplifying it.

The Problem Was Not the Code

When an application grows, adding features feels like progress.

A new menu here.

A new category there.

Another useful feature for users.

At some point, the application becomes larger, but not necessarily better.

Some features require continuous maintenance:

Updating content
Managing data
Fixing edge cases
Handling user reports
Testing across different devices

These tasks are manageable when there is a dedicated team.

But I am building and maintaining multiple applications by myself.

So I needed to make a decision.

Should I keep expanding MTA ONE into an application with many unrelated features?

Or should I return to the core purpose?

I chose the second option.

From Flutter to Kotlin Native

One of the biggest changes in MTA ONE v4 is the technology behind it.

The previous version was built with Flutter.

For version 4, I rebuilt it using Kotlin Native with Jetpack Compose.

The migration started around August 19, 2026, and the new version was released on August 21, 2026.

The reason was not because Flutter was bad.

Flutter helped me build the previous version faster.

But for this application, I wanted more control over the Android experience, especially for:

Media playback
Performance
System integration
Long-term maintenance

Moving to native Android gives me a stronger foundation for future development.

Removing Features Was a Difficult Decision

The previous MTA ONE version had several features that were useful:

Qibla direction
Offline Quran
Prayer guidance
Daily prayers
Hijri calendar
Weather information

However, useful does not always mean it should stay inside the application.

Every feature has a cost.

A feature is not only about writing code once.

It requires maintenance afterward.

For example:

A weather feature requires weather data.

A Quran feature requires content management.

A calendar feature requires accuracy and updates.

When many features are combined into one application, the responsibility grows significantly.

I realized that if I wanted MTA ONE to continue improving, I needed to reduce the scope.

Returning to the Core of MTA ONE

MTA ONE is now focused on the features that are directly connected with MTA content.

MTA TV

The main video experience remains.

Users can watch MTA TV directly from the application with a simpler interface.

Online Radio

MTA ONE provides access to online radio channels from different regions:

Persada FM — Solo / Sragen
Suara Kesuma FM — Wonosobo
Persada FM Pacitan — Pacitan
Persada Bali FM — Bali
Skar FM — Madiun
Kharisma FM — Pontianak

The goal is simple:

Open the application, select a channel, and listen.

Weekly Brochure

Users can access the latest MTA weekly brochures.

Instead of keeping a large archive, MTA ONE focuses on providing the latest content that users frequently need.

Prayer Schedule

Prayer schedules are still available for cities and districts across Indonesia.

MTA Updates and Information

Users can also access:

Latest MTA news
MTA profile
Official study location information

A Smaller Application, A Better Direction

This rebuild taught me something:

More features do not always create a better application.

Sometimes, removing features allows the important parts to become better.

MTA ONE v4 is not a bigger application than before.

It is a more focused application.

With a smaller scope, I can spend more time improving:

Stability
Performance
User experience
Long-term maintenance

For a solo developer, focus is not just a preference.

It is a requirement.

MTA ONE v4 is the next step in that direction.

A simpler foundation for future improvements.

MTA ONE v4 is now available.

Rebuilding Brosur MTA Lengkap: Why I Rebuilt an App That Already Worked

Cahyanudien Aziz Saputra — Tue, 04 Aug 2026 04:23:48 +0000

Sometimes the hardest decision in software development is not adding a new feature.

It is deciding to rebuild something that already works.

On August 3, 2026, I released Brosur MTA Lengkap version 4.0.0.

This release represents a major turning point.

It is not just an update.

It is a complete rebuild.

The uncomfortable decision

The previous version of Brosur MTA Lengkap was built with Flutter.

Flutter helped me move quickly, experiment with ideas, and bring the application to users faster.

For the early stage, it was the right decision.

But over time, the application changed.

It was no longer just a simple PDF reader.

It became a place where users could explore thousands of Islamic materials: brochures, articles, documents, and other educational content.

The needs became bigger:

Faster access to content.
Better offline support.
More reliable file management.
A stronger foundation for future development.

At that point, I had a choice:

Continue building on the existing foundation, or rebuild it properly.

I chose the harder path.

Rebuilding for the next phase

Rewriting an application means accepting that some previous work will be left behind.

It is not an easy decision.

There is always a temptation to keep adding features because the existing application already works.

But sometimes the biggest limitation is not the feature itself.

It is the foundation underneath it.

The goal was not simply changing technology.

The goal was creating an application that could continue growing for years.

From an app to a digital library

The vision for Brosur MTA Lengkap has changed.

Originally, the application was mainly a way to open and read PDF brochures.

Now, I see it as a small digital library.

A library needs more than documents.

It needs:

A simple way to discover content.
A reliable way to read.
A way to save important materials.
A way to find information quickly.

That is why version 4 focuses on the complete reading experience.

Designed around offline access

One important principle behind this rebuild is offline-first.

Knowledge should not disappear just because an internet connection is unavailable.

Version 4 improves local storage and caching so users can:

Access previously loaded content faster.
Keep reading history and favorites locally.
Open downloaded documents.
Search content without depending entirely on a server.

For educational applications, reliability matters.

The user should focus on learning, not on whether the connection is available.

Building a better way to find knowledge

As the number of documents grows, finding information becomes a challenge.

A library is only useful if people can find what they need.

That is why version 4 introduces offline full-text search.

The search system is designed to work with large amounts of content while providing more relevant results through ranking and language processing.

The goal is simple:

Help people find knowledge, not just files.

Why Kotlin Native?

This rebuild also moved the application from Flutter to Kotlin Native with Jetpack Compose.

This was not a decision because one technology is universally better than another.

Different tools are suitable for different stages.

Flutter was valuable when speed of development was the priority.

But for this next phase, I wanted deeper control over Android's native capabilities and a foundation closer to the platform where the application lives.

A new chapter for FlagoDNA

Brosur MTA Lengkap version 4 is part of a bigger direction for FlagoDNA.

I want to build software that is:

Useful.
Simple.
Privacy-respecting.
Accessible.

Not every application needs more notifications, more tracking, or more distractions.

Sometimes the best software is the one that quietly helps people accomplish something meaningful.

This rebuild is one step toward that direction.

Thank you to everyone who has used the application, shared feedback, and supported this project.

Version 4.0.0 is not the final destination.

It is a new foundation for what comes next.

Redesigning FlagoDNA Around a Mission, Not Products

Cahyanudien Aziz Saputra — Sun, 26 Jul 2026 05:32:49 +0000

Today, I launched a completely redesigned version of the FlagoDNA website.

At first glance, it might look like a visual refresh.

New layouts.

New sections.

Better typography.

A cleaner design.

But the biggest change isn't what you see.

It's the story the website tells.

The Website Wasn't the Problem

For a long time, the FlagoDNA homepage looked like many developer websites.

It showcased applications.

Visitors could browse Quran Today, HadisKu, Hijri Today, and other projects I had built over the years.

Technically, it worked.

But something was missing.

People understood what I had built.

Very few understood why I built it.

That realization completely changed how I approached the redesign.

I Never Wanted to Build Just Another App Portfolio

FlagoDNA never started with a business plan.

There wasn't a pitch deck.

There wasn't venture capital.

There wasn't even a goal to start a company.

I simply wanted to solve problems I experienced myself.

One application became another.

Each project taught me something—not only about software engineering, but about how technology quietly shapes the way people think, communicate, focus, and even practice their faith.

Eventually, I realized I wasn't just building applications anymore.

I was slowly building a philosophy.

The Real Problem Was Never Missing Apps

For years, I believed people simply needed better software.

Eventually, I realized something much bigger.

The real problem wasn't the lack of applications.

It was the digital environment surrounding them.

Modern software often competes for attention.

Notifications interrupt focus.

Advertisements become business models.

Personal data becomes a product.

Algorithms encourage people to stay longer instead of helping them leave sooner.

I didn't want FlagoDNA to become another company optimizing for engagement.

I wanted to build technology that respected people.

A Different Philosophy

That realization became the foundation of every product I build.

Before adding a feature, I ask a simple question.

Does this respect the user?

That question influences everything.

Does this feature really need an account?
Does it need an internet connection?
Are we collecting information we don't actually need?
Is this notification necessary?
Does this make life simpler—or noisier?

Those questions eventually became the principles behind FlagoDNA.

Privacy First.
No Ads.
No User Tracking.
No Selling Personal Data.
Respect Human Attention.

Technology should quietly support people—not manipulate them.

Why the Homepage Changed

The redesign wasn't about making the website prettier.

It was about telling the right story.

Previously, visitors arrived and immediately saw products.

Now they first see the mission.

Then the beliefs.

Then the principles.

Only after understanding those things do they discover the products.

Because Quran Today, HadisKu, Hijri Today, and every future project are not the story.

They're the proof.

They exist because they share the same philosophy.

Looking Beyond Individual Applications

Another reason for the redesign was to communicate where FlagoDNA is heading.

Many people naturally see FlagoDNA as an Android app developer.

That isn't wrong.

But it isn't the complete picture anymore.

The long-term vision is much broader.

FlagoDNA is gradually building a privacy-first digital ecosystem for Muslims.

Applications are only the beginning.

In the future, that ecosystem may include trusted AI, launcher experiences, shared infrastructure, developer tools, and other technologies that help Muslims embrace modern technology without sacrificing their faith, personal privacy, or attention.

Building for the Long Term

Many technology companies optimize for growth.

More engagement.

More impressions.

More advertisements.

More data.

I believe there is another way.

If someone opens one of my applications, accomplishes what they came to do, and then puts their phone away—that's success.

Technology shouldn't compete with life.

It should quietly support it.

More Than a New Website

Looking back, I don't think the previous website was bad.

It simply reflected an earlier stage of FlagoDNA.

Back then, I was focused on showing what I had built.

Today, I'm equally focused on explaining why it exists.

The redesign marks an important shift.

Not from one design to another.

But from presenting products to communicating a mission.

I hope that when someone visits FlagoDNA today, they don't simply think,

"This developer builds Android apps."

Instead, I hope they leave understanding something much more important.

FlagoDNA is building technology that respects faith, protects personal privacy, and values human attention.

Explore the New FlagoDNA

If you've followed my work over the years, thank you.

And if this is your first time hearing about FlagoDNA, welcome.

I invite you to explore the new website and discover the mission, beliefs, products, founder story, and long-term vision behind everything we're building.

I'd genuinely love to hear your thoughts.

Every conversation, suggestion, and piece of feedback helps shape what FlagoDNA becomes next.

The Story Behind Quran Today, the Ad-Free Quran App I Built for Myself

Cahyanudien Aziz Saputra — Fri, 17 Jul 2026 04:17:27 +0000

Why I stopped looking for an "Islamic super app" and built the simplest Quran app I could open every single day

(formerly known as FastiQuran)

I didn't build Quran Today because I thought the existing Quran apps were bad.

Quite the opposite. Many of them are genuinely excellent.

I built it because I was looking for a different kind of Quran reading experience — a free Quran app, with no ads, and no extra steps standing between me and actually reading.

It Started With Something Simple

I only had two Quran apps on my phone. Both are among the most popular on the Play Store, and honestly, they deserve to be.

They're packed with features. Prayer times, qibla direction, daily duas, dzikir, tafsir, translations, recitations from dozens of qaris, worship reminders, and a long list of other supporting tools.

I never saw that as a flaw.

The problem was on my end.

I realized that almost every time I opened one of those apps, I was only trying to do one thing.

I wanted to keep reading the Quran. Nothing more.

I never opened the qibla compass. I rarely checked prayer times. I almost never touched the extra features — features that were, honestly, very well made.

All I wanted was one simple experience.

Open the app. Return to the last verse. Read. Done.

Over time, it started to feel like Quran apps were quietly turning into Islamic super apps — while all I wanted was a quiet, digital mushaf.

I Wasn't Looking for More Features

So I started asking myself a question. If my needs were this simple, why did the apps I used keep getting more complex?

More menus. More screens. More things to click through before I could actually start reading.

Even the app size kept growing, carrying capabilities that might be useful to someone, somewhere — but that I almost never used.

I began to think that maybe I didn't need a more complete app.

What I actually needed was an app that was more honest about its one real purpose: helping someone read the Quran.

About Gamification

There's one more thing I kept coming back to.

Lately, more and more apps lean on gamification. Reading streaks. Badges. Stats. Daily targets. Notifications reminding you not to lose your progress.

I understand the reasoning. As someone who builds apps myself, I know these mechanics genuinely increase engagement.

But the more I sat with it, the more I felt that the Quran occupies a different kind of place in someone's life.

A person's relationship with the Quran isn't a relationship between a user and an app. It's a relationship between a servant and the word of their Lord.

I personally don't think that relationship needs to be propped up by numbers. It doesn't need to be protected by the fear of breaking a streak. It doesn't need to feel like a game you're supposed to win.

If today I read one page with real presence of heart, that's already enough. If tomorrow I read less, my relationship with the Quran still isn't something a graph can measure.

Plenty of people genuinely like gamification, and there's nothing wrong with that. I just know I'm not one of them.

So I Decided to Build It Myself

That's where Quran Today was born.

Not out of a desire to build something more impressive. Not because I thought I could build the "best" Quran app out there.

I just wanted to build the app I myself would want to open every day.

The principle was simple:

When you open the app, it takes you straight back to your last read verse.
No friction before you start reading.
No feature that exists just because "every other app has it."
No ads.
No tracking of reading habits.
No streaks.
No virtual rewards.

I wanted an app that, once opened, barely feels like it's there at all. Because the focus was never meant to be the app.

It was always meant to be the Quran.

Building It Turned Out to Be Harder Than It Sounded

The first version of Quran Today was built in Flutter. It shipped. It launched successfully.

But the results were unremarkable. About five hundred people installed it.

At first, I was disappointed. I wondered if I'd just built yet another version of something that already existed hundreds of times over.

After sitting with that for a while, though, I realized the idea wasn't the problem. How I built it was.

The user experience wasn't mature enough. A lot of the design decisions hadn't actually solved the problem I originally set out to solve.

That's when I made a fairly drastic call. I rebuilt everything from scratch.

Not just a new tech stack — I restructured almost the entire foundation of the app. The codebase was simplified to be easier to maintain and extend. The interface was redesigned over and over until it finally felt natural to use.

I spent a surprising amount of time on questions that seemed small.

What's the most comfortable way to switch between surahs? Does the app even need a home screen? Should the surah list fill the whole screen, appear as a panel, or just be a simple dialog? How should verses be displayed — as cards, like modern apps do, or flowing continuously, like a mushaf?

Questions like these ended up taking far more time than writing the code itself.

There Were Moments I Wanted to Quit

Not every day felt good.

Some nights I closed my laptop not because the work was done, but because my head was simply too full.

Sometimes I'd think, "Is any of this actually worth it?"

I think almost anyone who's ever built something alone has had that moment.

But every time that question came up, I kept coming back to the same answer.

If an app like this didn't exist yet, then I'd build it. And if it turned out that I was the only one who ever used it, that would be fine too — because I built it for myself in the first place.

I've Made Peace With That Possibility

Quran Today may never become the number one Quran app.

It may never have millions of users. It may never go viral.

And I'm genuinely at peace with that.

I'd rather have an app I actually open every single day than one that's wildly popular but has lost the reason it was built in the first place.

If it turns out other people are also looking for a calm, simple, distraction-free way to read the Quran, I'll be genuinely grateful. It would mean I'm not alone in wanting this.

Why the Name Changed

The app was originally called FastiQuran.

That name came from an idea about speed. Fast to open. Fast to use. Fast to get back to reading.

But the longer I worked on it, the more I realized that name only explained how the app worked. Not why it existed.

Eventually I landed on two words that felt much closer to the real purpose.

Quran Today.

Because in the end, this app was never really about speed. Never about technology. Never about how many features it had.

It just wants to be ready, whenever someone wants to come back to the Quran — today.

Today. At the exact verse they left off. Without friction. Without pressure. Without needing to be anything more than someone who reads the Quran.

I don't know if Quran Today will ever become a big app.

But I know one thing.

Tomorrow morning, when I want to read the Quran again, this is the app I'll open.

And maybe that's the best reason Quran Today exists at all.

If you're also looking for a calm Quran app — no ads, no account, no streaks making you feel guilty for missing a day — Quran Today is free to download on Google Play. No hidden costs, no premium tier. Install it once, and every time you open it, you're right back at the last verse you read.

Quran Today: Ketika Saya Memutuskan Menghapus Semua yang Tidak Penting

Cahyanudien Aziz Saputra — Thu, 16 Jul 2026 18:41:53 +0000

Bagaimana jika aplikasi Al-Qur'an tidak mencoba melakukan segalanya?

Bagaimana jika ia hanya membantu kita membaca?

Selama bertahun-tahun saya menggunakan dan mencoba banyak aplikasi Al-Qur'an.

Sebagian memiliki fitur yang sangat lengkap. Ada dashboard, statistik, tantangan membaca, gamifikasi, akun, sinkronisasi cloud, hingga berbagai menu yang terus bertambah.

Semuanya bagus.

Namun suatu hari saya bertanya pada diri sendiri.

Apakah saya benar-benar membutuhkan semua itu ketika ingin membaca Al-Qur'an?

Jawaban saya ternyata sederhana.

Tidak.

Saya hanya ingin membuka aplikasi, lalu langsung membaca.

Berawal dari FastiQuran

Sebelum bernama Quran Today, aplikasi ini dikenal sebagai FastiQuran.

Awalnya proyek ini hanyalah eksperimen pribadi.

Saya mencoba membuat pengalaman membaca yang lebih sederhana dibanding aplikasi Al-Qur'an pada umumnya.

Seiring waktu, saya mulai menyadari bahwa arah aplikasinya semakin jelas.

Bukan menjadi aplikasi dengan fitur paling banyak.

Melainkan menjadi aplikasi yang paling nyaman digunakan untuk membaca.

Karena itu saya memutuskan mengganti namanya menjadi Quran Today.

Nama baru ini lebih mencerminkan tujuan utamanya.

Membaca Al-Qur'an hari ini.

Dan melanjutkannya lagi besok.

Saya Menghapus Banyak Hal

Saat mengembangkan Quran Today, saya justru lebih sering menghapus daripada menambahkan fitur.

Saya menghapus hal-hal yang menurut saya mengganggu proses membaca.

Saya bertanya berulang kali.

Apakah fitur ini benar-benar membantu seseorang membaca Al-Qur'an?

Jika jawabannya tidak jelas, saya memilih untuk tidak menambahkannya.

Semakin sedikit langkah yang harus dilakukan pengguna sebelum mulai membaca, semakin baik.

Tidak Ada Dashboard

Ketika membuka Quran Today, Anda tidak akan menemukan halaman beranda.

Tidak ada kartu informasi.

Tidak ada statistik.

Tidak ada menu yang harus dilewati.

Aplikasi langsung membawa Anda kembali ke ayat terakhir yang dibaca.

Bagi saya, layar terbaik adalah layar yang membuat pengguna segera membaca.

Privasi Bukan Fitur Tambahan

Saya percaya membaca Al-Qur'an adalah aktivitas yang bersifat pribadi.

Karena itu Quran Today dibuat dengan prinsip yang sederhana.

Tidak perlu akun.
Tidak perlu login.
Tidak ada analytics.
Tidak ada pelacakan.
Tidak ada iklan.

Seluruh progres membaca, bookmark, daftar hafalan, dan pengaturan tetap berada di perangkat pengguna.

Saya tidak ingin mengetahui kapan seseorang membaca Al-Qur'an.

Saya juga tidak ingin mengumpulkan data yang sebenarnya tidak saya perlukan.

Gratis Selamanya

Quran Today tidak memiliki langganan.

Tidak ada fitur premium.

Tidak ada iklan.

Semua fitur tersedia sejak pertama kali aplikasi dipasang.

Saya ingin setiap orang dapat menikmati pengalaman membaca yang sama, tanpa harus membayar untuk membuka fitur tertentu.

Dibangun Ulang dari Flutter ke Kotlin

Salah satu keputusan terbesar selama pengembangan adalah memindahkan proyek ini dari Flutter ke Kotlin Native menggunakan Jetpack Compose.

Keputusan ini tidak mudah.

Artinya saya harus menulis ulang hampir seluruh aplikasi.

Namun hasilnya sepadan.

Rendering teks Arab menjadi lebih baik.

Scrolling terasa lebih halus.

Integrasi Android menjadi lebih alami.

Dan saya memiliki kontrol yang lebih besar terhadap performa aplikasi.

Dibuat oleh Satu Orang

Quran Today tidak dibuat oleh sebuah tim besar.

Tidak ada desainer.

Tidak ada product manager.

Tidak ada investor.

Saya mengerjakan semuanya sendiri.

Mulai dari desain antarmuka, pemrograman, optimasi database, terjemahan, hingga halaman website dan dokumentasi.

Perjalanannya memang lebih lambat.

Tetapi saya menikmati setiap prosesnya.

Saya Berharap...

Saya tidak berharap Quran Today menjadi aplikasi Al-Qur'an terbesar.

Saya hanya berharap ketika seseorang ingin membaca Al-Qur'an, aplikasi ini tidak menghalangi niat baiknya.

Ia cukup membuka aplikasi.

Dan langsung membaca.

Kalau suatu hari ada seseorang yang berkata,

"Saya jadi lebih sering membaca Al-Qur'an karena aplikasi ini."

Mungkin itu sudah menjadi pencapaian terbesar bagi saya.

Ingin Mencobanya?

Quran Today adalah proyek independen yang saya bangun seorang diri dengan satu tujuan sederhana: membuat pengalaman membaca Al-Qur'an menjadi lebih nyaman, lebih tenang, dan tanpa gangguan.

Jika menurut Anda filosofi tersebut menarik, silakan mencobanya.

Masukan, kritik, maupun saran akan sangat berarti untuk membantu Quran Today menjadi aplikasi yang lebih baik.

Terima kasih telah menggunakan Quran Today.

Semoga aplikasi kecil ini bisa menjadi teman dalam perjalanan membaca Al-Qur'an, satu ayat demi satu ayat.

Dari Satu Pertanyaan Ibu, Sebuah Aplikasi Digunakan di Berbagai Belahan Dunia

Cahyanudien Aziz Saputra — Fri, 26 Jun 2026 13:10:51 +0000

Terkadang sebuah aplikasi tidak lahir dari ide startup.

Ia lahir dari seseorang yang kita sayangi.

Saya tidak pernah memiliki rencana membuat aplikasi kalender Hijriah.

Tidak ada business plan.

Tidak ada riset pasar.

Tidak ada target unduhan.

Semuanya berawal dari satu percakapan sederhana dengan ibu saya.

Sebuah Pertanyaan yang Sangat Sederhana

Suatu hari ibu saya berkata,

"Besok Ayyamul Bidh ya? Sekarang sudah tanggal berapa Hijriah?"

Saya menyadari sesuatu.

Kalender Masehi ada di mana-mana.

Di ponsel.

Di laptop.

Di jam tangan.

Di kalender dinding.

Tetapi kalender Hijriah sering kali harus dicari terlebih dahulu, padahal banyak ibadah bergantung padanya.

Puasa Ayyamul Bidh
Puasa Arafah
Awal Ramadan
Hari Raya
Bulan-bulan Haram
Dan berbagai momen penting lainnya

Saya berpikir,

"Kalau ibu saya mengalami kesulitan ini, mungkin banyak orang lain juga mengalaminya."

Saya Hanya Ingin Membantu Ibu

Saat mulai membuat Hijri Today, saya tidak pernah berpikir tentang monetisasi.

Saya hanya bertanya kepada diri sendiri:

Apakah ibu saya bisa menggunakannya?
Apakah tampilannya cukup sederhana?
Apakah tanggal Hijriahnya mudah dibaca?
Apakah beliau bisa langsung mengetahui hari ini tanggal berapa?

Kalau semua itu terjawab, berarti aplikasi ini sudah berhasil.

Setelah Selesai...

Saya mengunggahnya ke Google Play.

Dengan keputusan yang sangat sederhana.

✅ Gratis
✅ Tanpa iklan
✅ Tanpa langganan
✅ Tanpa pembelian dalam aplikasi

Saya tidak meminta siapa pun untuk mengunduhnya.

Saya juga tidak menjalankan kampanye pemasaran.

Saya hanya menekan tombol Publish.

Lalu melanjutkan hidup seperti biasa.

Sampai Suatu Hari...

Beberapa waktu kemudian saya mulai membuka statistik Google Play Console.

Awalnya saya hanya melihat jumlah unduhan.

Lalu perhatian saya beralih ke daftar negara.

Bukan hanya Indonesia.

Ada India.

Pakistan.

Mesir.

Nigeria.

Somalia.

Malaysia.

Arab Saudi.

Inggris.

Amerika Serikat.

Dan masih banyak negara lainnya.

Saya sempat berhenti beberapa saat.

Bagaimana mereka bisa menemukan aplikasi kecil yang dibuat seseorang dari Indonesia?

Hari Ini

Berikut beberapa negara dengan jumlah pengguna aktif terbesar saat saya menulis artikel ini.

Negara	Pengguna
🇮🇩 Indonesia	298
🇮🇳 India	284
🇵🇰 Pakistan	278
🇪🇬 Mesir	215
🇳🇬 Nigeria	134
🇸🇴 Somalia	99
🇲🇾 Malaysia	87
🇬🇧 Inggris	84
🇸🇦 Arab Saudi	83
🇺🇸 Amerika Serikat	59
🇪🇹 Ethiopia	49
🇨🇮 Pantai Gading	46
🇰🇪 Kenya	44

Dan masih banyak pengguna dari negara-negara lainnya.

Yang Membuat Saya Bersyukur

Yang paling membuat saya bersyukur bukanlah angka unduhannya.

Bukan pula jumlah negara yang tercatat.

Tetapi membayangkan bahwa seseorang di Pakistan...

atau Mesir...

atau Somalia...

sedang membuka aplikasi yang awalnya saya buat hanya untuk membantu ibu saya.

Saya tidak mengenal mereka.

Mereka juga tidak mengenal saya.

Namun kami dipertemukan oleh sebuah aplikasi sederhana.

Saya Tidak Mengejar Validasi

Banyak orang bertanya mengapa aplikasi saya gratis.

Mengapa tidak dipenuhi iklan.

Mengapa tidak dibuat berlangganan.

Jawaban saya sederhana.

Sejak awal saya memang tidak membangunnya untuk itu.

Saya hanya ingin membuat sesuatu yang berguna.

Kalau suatu hari seseorang bisa menjalankan ibadah dengan lebih mudah karena aplikasi yang saya buat, rasanya itu sudah cukup berarti.

Pelajaran yang Saya Dapat

Saya belajar bahwa tidak semua karya harus dimulai dari masalah yang besar.

Kadang justru dimulai dari pertanyaan yang sangat dekat.

"Masalah apa yang sedang dialami orang tua saya?"

Ketika kita menyelesaikan masalah yang nyata, sering kali ternyata ribuan orang lain mengalami masalah yang sama.

Sebelum Hidup Ini Selesai

Saya tidak tahu berapa lama lagi saya bisa terus membuat aplikasi.

Tetapi saya berharap, sebelum hidup ini selesai, saya pernah meninggalkan sesuatu yang benar-benar bermanfaat bagi orang lain.

Tidak harus menjadi perusahaan besar.

Tidak harus menjadi aplikasi nomor satu.

Tidak harus dikenal banyak orang.

Cukup menjadi alat yang membantu seseorang.

Kalau suatu hari ada seseorang di belahan dunia lain yang mengetahui tanggal Hijriah hari itu melalui aplikasi yang awalnya saya buat untuk ibu saya, maka saya rasa perjalanan ini tidak sia-sia.

Aplikasi Kasir Gratis yang Jujur: Kenapa KasirCepat Berbeda dari Aplikasi POS Lainnya

Cahyanudien Aziz Saputra — Thu, 11 Jun 2026 03:34:05 +0000

Warung dan toko kecil Indonesia layak mendapatkan software yang tidak mengeksploitasi mereka.

Kalau kamu pernah mencoba aplikasi kasir digital untuk warung atau toko kelontong, kamu mungkin sudah familiar dengan rasa frustasi ini:

Produk ke-31 tiba-tiba terkunci. Riwayat transaksi bulan lalu hilang. Aplikasinya tidak bisa dipakai waktu internet mati. Dan di suatu hari, kamu membaca privacy policy-nya — dan menemukan bahwa data penjualan tokomu bisa "dianalisa dan dilisensikan ke pihak ketiga."

Ini bukan skenario hipotetikal. Ini adalah praktik nyata yang dilakukan banyak aplikasi kasir populer di Indonesia hari ini.

KasirCepat hadir sebagai jawaban atas masalah ini.

Apa Itu KasirCepat?

KasirCepat adalah aplikasi POS (Point of Sale) offline-first yang dirancang khusus untuk warung, toko kelontong, kios pasar, dan usaha kecil di Indonesia.

Tersedia di tiga platform:

Android (Google Play Store)
Windows (Windows 10/11)
Linux (Ubuntu, Debian, Fedora)

Gratis selamanya untuk 1 perangkat — tanpa batas produk, tanpa batas transaksi, tanpa iklan.

Masalah yang Coba Diselesaikan

Sebelum bicara soal fitur, penting untuk memahami mengapa KasirCepat dibuat.

Mayoritas aplikasi kasir di pasar hari ini dibangun dengan model bisnis yang pada dasarnya bertentangan dengan kepentingan pengguna kecil:

1. Paywall yang agresif
Setelah memasukkan 30 produk, kamu dipaksa berlangganan. Ini bukan fitur premium — ini fitur dasar yang sengaja dikunci.

2. Data yang hilang tanpa izin
Riwayat transaksi dihapus otomatis setelah periode tertentu. Bagi pemilik toko kecil, data ini adalah catatan bisnis mereka yang paling berharga.

3. "Offline mode" yang palsu
Banyak aplikasi mengklaim bisa digunakan offline, tapi sinkronisasi dan login tetap butuh koneksi internet. Di area dengan sinyal tidak stabil — yang sangat umum di Indonesia — ini adalah masalah nyata.

4. Privasi data yang dipertanyakan
Data transaksi tokomu — produk apa yang laku, jam berapa ramai, berapa margin keuntunganmu — adalah data bisnis yang sangat berharga. Beberapa aplikasi memperbolehkan data ini dianalisa dan dijual ke pihak ketiga.

KasirCepat membangun solusi dari nol dengan filosofi yang berlawanan: tokomu, datamu, kendalimu.

Fitur Utama KasirCepat

🛒 Kasir (POS) yang Cepat dan Simpel

Alur transaksi dirancang untuk kasir yang memegang HP saat toko ramai:

Cari produk dengan ketuk atau scan barcode langsung dari kamera
Tambah ke keranjang, stok berkurang otomatis
Pilih metode pembayaran: Tunai, Transfer, QRIS, atau Utang
Kembalian dihitung otomatis
Tombol cepat nominal Rp 10.000 – Rp 1.000.000
Print struk thermal (58mm/80mm) atau kirim via WhatsApp

Satu layar. Satu alur. Langsung bisa dipakai tanpa training.

📦 Manajemen Produk Lengkap

Nama, harga jual, harga modal, dan stok
Scanner barcode langsung dari kamera HP
Foto produk dari kamera
Kategori produk custom
Notifikasi stok menipis
Import/Export produk via CSV (kompatibel Excel)

📋 Riwayat Transaksi yang Tidak Pernah Dihapus

Ini adalah salah satu komitmen paling penting KasirCepat: riwayat transaksi tidak pernah dihapus otomatis.

Filter berdasarkan hari ini, 7 hari, atau bulan ini. Lihat total pendapatan dan laba bersih. Edit atau hapus transaksi (stok otomatis kembali). Cetak ulang struk kapanpun.

⚙️ Backup & Export Data

Backup data lokal dengan password
Restore kapanpun dari file backup
Export CSV transaksi dan produk
Export PDF laporan penjualan
Import produk dari CSV

Offline-First: Bukan Fitur, Tapi Arsitektur

Ini adalah perbedaan fundamental yang perlu dipahami.

Sebagian besar aplikasi kasir memiliki "mode offline" sebagai fallback — artinya, sistem utamanya tetap bergantung pada koneksi internet, dan offline hanya diaktifkan saat koneksi terputus.

KasirCepat dirancang sebaliknya: offline adalah mode utama. Data tersimpan sepenuhnya di perangkatmu. Tidak ada data transaksi yang dikirim ke server KasirCepat — titik.

Untuk pemilik toko yang menggunakan beberapa perangkat (misalnya HP kasir dan laptop owner), sinkronisasi dilakukan lewat WiFi toko — tanpa internet, tanpa akun cloud.

Paket Harga yang Transparan

Paket	Harga	Untuk Siapa
Free	Rp 0 selamanya	Toko dengan 1 perangkat
Pro	Rp 129.000/tahun	Toko dengan beberapa kasir/perangkat
Cloud+	TBD (belum tersedia)	Multi-cabang (opsional di masa depan)

Paket Free mencakup POS penuh, produk dan transaksi tidak terbatas, riwayat lengkap, laporan harian, dan backup/restore lokal.

Paket Pro menambahkan fitur multi-device via WiFi lokal, auto print struk, scanner barcode USB/Bluetooth, dan laporan yang lebih lengkap.

Yang penting: fitur gratis tidak akan pindah ke Pro. Ini bukan janji marketing — ini komitmen produk yang tertulis jelas.

Untuk Siapa KasirCepat Cocok?

KasirCepat paling cocok untuk:

Warung dan toko kelontong yang ingin mencatat transaksi digital tanpa ribet
Kios pasar dengan koneksi internet yang tidak stabil
Toko dengan 1-3 kasir yang butuh sistem multi-perangkat tanpa biaya cloud
Pemilik usaha kecil yang peduli dengan privasi data bisnis mereka
Kasir pemula yang butuh UI simpel dan bisa langsung dipakai

Filosofi di Balik Produk

Ada satu kutipan dari halaman produk KasirCepat yang cukup menggambarkan filosofinya:

"Kompetitor membangun kasir untuk investor mereka. Kami membangun kasir untuk tokomu."

Ini bukan sekadar tagline. Keputusan produk mereka — dari arsitektur offline-first, data yang tidak pernah meninggalkan perangkat, sampai fitur gratis yang tidak dikunci — semuanya konsisten dengan filosofi ini.

Di industri SaaS yang sering mengutamakan growth metric di atas pengalaman pengguna, pendekatan ini terasa menyegarkan.

KasirCepat Officially Launches: Free Offline-First POS for Indonesia's Small Businesses

Cahyanudien Aziz Saputra — Wed, 10 Jun 2026 04:27:55 +0000

Surakarta, Indonesia — June 2026 — Flagodna today announced the official launch of KasirCepat, a free offline-first point-of-sale (POS) application designed specifically for small businesses, market stalls, street vendors, and micro enterprises across Indonesia.

Built with a simple principle — a cashier system should continue working even when the internet does not — KasirCepat aims to provide a practical alternative to cloud-dependent POS solutions that may become difficult to use in areas with unstable connectivity.

Built for Real Business Conditions

Many small businesses across Indonesia operate in environments where internet access is not always reliable. Yet most modern POS systems assume a constant online connection.

KasirCepat was developed with a different approach.

Rather than relying on remote servers for daily operations, the application stores business data locally on the user's device. Sales transactions, inventory management, product catalogs, reports, and customer records remain accessible even when the internet is unavailable.

This offline-first architecture ensures businesses can continue operating without interruptions caused by network outages.

Designed Around Simplicity

The goal of KasirCepat is not to become the most feature-packed POS system on the market.

Instead, it focuses on helping merchants complete everyday transactions quickly and efficiently.

Core capabilities include:

Product and inventory management
Barcode scanning
Real-time stock tracking
Automatic cash change calculation
Multiple payment methods
Thermal receipt printing
Digital receipts via WhatsApp
Daily sales and profit reports
CSV import and export
Backup and restore functionality

The application is designed to remain lightweight, responsive, and easy to learn for first-time users.

Privacy-First by Design

Flagodna believes business owners should retain control over their own data.

For that reason, KasirCepat is designed so that day-to-day business operations do not depend on external servers.

Transaction records, inventory data, and business information remain under the merchant's control.

This approach helps reduce reliance on third-party services while providing a more transparent experience for users.

Available Across Multiple Platforms

KasirCepat is available on:

Android
Windows
Linux

Businesses can choose the platform that best fits their workflow while maintaining access to their data through built-in backup and restore functionality.

For users who require multi-device operation, KasirCepat also supports local WiFi synchronization, allowing devices to communicate directly within the same network without requiring cloud infrastructure.

A Genuinely Free Tier

Unlike many POS solutions that impose transaction limits, product limits, or advertising, KasirCepat offers:

Unlimited products
Unlimited transactions
No advertisements
No mandatory subscription

The objective is simple: provide accessible business software that small businesses can adopt without unnecessary barriers.

A Message from the Founder

"Many POS systems are designed around the assumption that internet access is always available," said Mochammad Zuhri, Founder of Flagodna.

"KasirCepat was built with a different assumption: merchants should be able to continue selling regardless of network conditions. Technology should support business operations, not become another dependency."

About KasirCepat

KasirCepat is an offline-first POS application developed by Flagodna for small businesses, market stalls, retail stores, and micro enterprises in Indonesia.

The software focuses on speed, simplicity, privacy, and user control while providing essential tools required for daily business operations.

Availability

KasirCepat is available now.

141 Jam Membangun Aplikasi Kasir yang Tidak Terlihat Seperti Excel

Cahyanudien Aziz Saputra — Tue, 09 Jun 2026 14:29:10 +0000

Saya tidak pernah berencana membuat aplikasi kasir.

Kalau beberapa tahun lalu ada yang bilang saya akan menghabiskan lebih dari 141 jam membangun aplikasi POS, mungkin saya akan tertawa.

Namun semuanya berubah setelah saya melihat bagaimana banyak aplikasi kasir digunakan di dunia nyata.

Bukan saat dipresentasikan.

Bukan saat dipromosikan.

Bukan saat ada demo yang sudah disiapkan dengan rapi.

Melainkan saat benar-benar digunakan untuk bekerja.

Dan yang saya lihat membuat saya tidak nyaman.

Tampilannya seperti Excel yang dipaksa menjadi aplikasi.

Kolom di mana-mana.

Tabel memenuhi layar.

Tombol kecil berjejer tanpa prioritas.

Menu bertingkat.

Laporan yang lebih menonjol daripada transaksi.

Grafik yang terlihat mengesankan tetapi jarang disentuh.

Saya melihat beberapa aplikasi kasir dan terus memikirkan satu pertanyaan:

Siapa sebenarnya yang menggunakan aplikasi ini?

Karena yang saya lihat bukan akuntan.

Bukan analis data.

Bukan orang yang duduk delapan jam di depan monitor.

Yang saya lihat adalah pemilik warung.

Penjual gorengan.

Pemilik toko kelontong.

Pedagang kecil yang harus melayani pembeli, menerima barang, menghitung stok, menjawab telepon, dan menyelesaikan banyak hal sekaligus.

Mereka tidak membuka aplikasi untuk menganalisis data.

Mereka membuka aplikasi untuk menyelesaikan transaksi.

Semakin saya melihat, semakin saya merasa ada sesuatu yang terbalik.

Banyak software modern terlihat hebat saat dipresentasikan.

Dashboard penuh grafik.

Statistik.

Insight.

Analitik.

Animasi.

Integrasi.

Semuanya terlihat mengesankan.

Tetapi saya mulai bertanya:

Apakah semua ini benar-benar membantu pengguna?

Atau hanya terlihat bagus saat dipresentasikan kepada investor, manajer, atau calon pelanggan?

Karena semakin lama saya mengamati, semakin sering saya menemukan pola yang sama.

Software dibuat dengan fokus pada apa yang bisa ditambahkan.

Bukan pada apa yang bisa disederhanakan.

Padahal pengguna tidak membeli kompleksitas.

Mereka membeli kemudahan.

Kebutuhan mereka sebenarnya sederhana.

Cari barang.
Masukkan jumlah.
Terima pembayaran.
Selesai.

Empat langkah.

Tidak lebih.

Namun entah bagaimana empat langkah sederhana itu sering berubah menjadi antarmuka yang terasa seperti sistem administrasi perusahaan besar.

Saya tidak mengatakan semua aplikasi kasir buruk.

Saya hanya merasa banyak di antaranya dibangun dari perspektif yang berbeda dengan penggunanya.

Lalu muncul pertanyaan yang terus mengganggu saya.

Bagaimana jika aplikasi kasir berhenti mencoba menjadi segalanya?

Bagaimana jika ia hanya fokus menjadi kasir yang baik?

Bukan yang paling lengkap.

Bukan yang paling canggih.

Bukan yang paling banyak fitur.

Hanya menjadi alat yang membantu orang menyelesaikan pekerjaannya.

Cepat.

Jelas.

Tanpa membuat pengguna berpikir terlalu banyak.

Pertanyaan itu terus muncul sampai akhirnya saya memutuskan untuk membangun sendiri jawabannya.

Jawaban itu saya beri nama KasirCepat.

Saya memulai dari prinsip yang sangat sederhana.

Offline bukan fitur tambahan.

Offline adalah fondasi.

Internet mati bukan kejadian langka.

Terutama bagi banyak usaha kecil di Indonesia.

Jika aplikasi berhenti bekerja ketika koneksi hilang, maka aplikasi tersebut gagal menjalankan tugas utamanya.

Karena transaksi tidak menunggu sinyal kembali.

Speed lebih penting daripada efek visual.

Saya berkali-kali membuang ide yang sebenarnya terlihat menarik.

Animasi.

Efek transisi.

Komponen tambahan.

Bukan karena semuanya buruk.

Tetapi karena setiap tambahan memiliki biaya.

Dan biaya itu dibayar oleh pengguna dalam bentuk waktu.

Satu layar, satu tujuan.

Saya tidak ingin pengguna membuka halaman transaksi lalu harus mencari tombol yang dibutuhkan.

Saya tidak ingin pengguna merasa tersesat.

Setiap layar harus memiliki tujuan yang jelas.

Sesederhana mungkin.

Ada alasan lain yang lebih personal.

Saya muak melihat software yang terasa dibuat untuk dipresentasikan.

Bukan untuk digunakan.

Dashboard yang indah belum tentu nyaman digunakan setiap hari.

Grafik yang keren belum tentu membuat transaksi lebih cepat.

Fitur yang panjang belum tentu menyelesaikan masalah.

Kadang yang dibutuhkan pengguna hanyalah sesuatu yang bekerja.

Dan terus bekerja.

Tanpa membuat hidup mereka lebih rumit.

141 jam. Tiga minggu. Dua hari demam.

Kalau dihitung, angka itu sebenarnya tidak terlalu istimewa.

Banyak orang menghabiskan waktu lebih lama untuk membangun sesuatu.

Tetapi bagi saya, angka itu menyimpan cerita yang berbeda.

Karena tidak ada investor yang menunggu.

Tidak ada perusahaan yang memberi tenggat waktu.

Tidak ada tim besar yang mendorong pekerjaan ini maju.

Hanya saya.

Laptop.

Dan keyakinan bahwa masalah ini layak diselesaikan.

Dua hari di antaranya saya bahkan sedang demam.

Saya masih ingat membuka laptop sambil berpikir bahwa mungkin saya seharusnya beristirahat.

Tetapi setiap kali menutup layar, pikiran itu kembali lagi.

Mengapa pekerjaan sederhana harus terasa rumit hanya karena software yang digunakan?

Pertanyaan itu terdengar kecil.

Tetapi justru pertanyaan kecil seperti itulah yang membuat banyak produk lahir.

Sebelum KasirCepat, ada banyak hal yang tidak berjalan sesuai rencana.

Interview yang gagal.

Email yang tidak pernah mendapat balasan.

Proyek yang selesai dibangun tetapi hampir tidak mendapat perhatian.

Mungkin sebagian besar pembuat produk independen pernah mengalami fase seperti itu.

Fase ketika kita mulai mempertanyakan apakah semua usaha yang dilakukan benar-benar berarti.

Saya juga pernah berada di titik itu.

Dan mungkin sesekali masih berada di sana.

Tetapi KasirCepat terasa berbeda.

Karena untuk pertama kalinya saya tidak membayangkan angka unduhan.

Saya tidak membayangkan statistik.

Saya tidak membayangkan pertumbuhan pengguna.

Saya membayangkan seseorang membuka aplikasi ini sebelum tokonya buka.

Menggunakannya sepanjang hari.

Lalu menutup tokonya tanpa harus berdebat dengan aplikasi yang ia gunakan.

Gambaran itu terasa jauh lebih nyata daripada grafik apa pun.

Pada akhirnya, ini bukan cerita tentang aplikasi kasir.

Ini cerita tentang rasa hormat terhadap waktu pengguna.

Tentang keyakinan bahwa software seharusnya membuat pekerjaan lebih mudah, bukan lebih rumit.

Tentang keberanian untuk menghapus sesuatu ketika tidak diperlukan.

Tentang memilih kesederhanaan ketika kompleksitas terlihat lebih mengesankan.

Dan mungkin, tentang keyakinan yang agak keras kepala bahwa hal-hal kecil tetap layak diperjuangkan.

Bahkan ketika tidak banyak orang yang memperhatikannya.

Jika ada satu hal yang ingin saya capai.

Saya tidak ingin membuat aplikasi kasir terbesar.

Saya tidak ingin membuat aplikasi kasir paling canggih.

Saya hanya ingin membuat aplikasi yang membantu seseorang bekerja sedikit lebih mudah hari ini dibanding kemarin.

Kalau itu berhasil terjadi, maka 141 jam, tiga minggu, dan dua hari demam terasa seperti harga yang layak dibayar.

Coba KasirCepat

KasirCepat adalah aplikasi kasir offline untuk UMKM Indonesia.

Tersedia untuk Android, Windows, dan Linux.

Gratis digunakan.

Tanpa batas transaksi.
