Swapping Backdrops in a Flame Endless Runner Without Tanking Frame Rate

Muhammad Aamir Yameen — Wed, 15 Jul 2026 06:50:08 +0000

20 unique environments sounds like an asset-loading and memory nightmare for a game that's supposed to run smooth on low-end Android devices.

The approach: How backdrops are loaded/swapped as the road scrolls — lazy loading vs. preloading, how you avoid a hitch when the environment changes, any texture/asset budget you set per scene.

Performance notes: Real frame-time numbers if you've profiled this, and what you'd do differently on a device with less headroom.

Capture-first, organize-never: the design bet behind Thinkora

Muhammad Aamir Yameen — Tue, 14 Jul 2026 11:24:28 +0000

Every note app I've built or used eventually failed the same way: it asked the user to maintain a system. Folders to sort, tags to apply, a workflow to keep alive. That upfront cost is where retention dies.

With Thinkora, I made the opposite bet: minimize capture latency, make organization optional.

🎤 Voice capture — speak, and it's a note/task instantly
🔥 Streaks — a lightweight habit loop
☀️ Morning Brew — a generated daily brief
🗓️ Smart calendar with holidays built in
✅ Notes, tasks, reminders, rich text, folders & tags (if you want them)
Stack: React Native, Android-first (rich editor, voice, Notifee), context-based state with local persistence, in a clean core / services / components / screens layout.

Do you think "organize later" scales, or does entropy always win?

One thing I didn't expect to spend so much time on while building NitroRush: Traffic Escape — the scenery.

Muhammad Aamir Yameen — Tue, 14 Jul 2026 10:13:54 +0000

It's an endless racer, so technically players could stare at one road forever and the game would still "work." But 20 hand-painted backdrops later, I think it mattered. Pine forests, cherry blossoms, northern lights — small visual variety turned out to change how long people actually stay in a run.

Curious if other devs have data on this: does environmental variety measurably affect retention in endless-runner genres, or is it just a nice-to-have?

Building an Adaptive Difficulty System for a Flutter/Flame Endless Racer

Muhammad Aamir Yameen — Fri, 10 Jul 2026 09:56:42 +0000

Endless racers live or die on pacing. Too easy and players get bored; too hard and they bounce after one run. A fixed difficulty curve fails because it can't tell a first-timer from someone who's run this track 200 times.

The approach: Track a rolling average of how far the player gets before crashing, and expose a difficulty multiplier that scales within a bounded range so the game never gets punishingly hard or trivially easy. Walk through why you picked that floor/ceiling.

Object pooling for endless spawns: Traffic, hazards, and power-ups never stop spawning in an endless runner — allocating a new object every spawn is a garbage-collection problem waiting to happen. Show the reuse pattern instead of allocating fresh instances.

Combo system as a risk/reward lever: Most obstacle games punish proximity. This one rewards it — near-misses stack a multiplier. Explain the design reasoning: this is what turns a dodge-em-up into something replayable.

What shipped, what didn't: Ghost replay made it in. Something else didn't — and why. Trade-offs are the useful part of a post like this.

I built Thinkora — a note app that captures your thoughts before they escape

Muhammad Aamir Yameen — Thu, 11 Jun 2026 07:52:39 +0000

We've all lost a good idea to bad timing. You think of something brilliant mid-commute, tell yourself "I'll write it down later," and — gone.

I kept hitting that wall, so I built Thinkora, a thought-capture app for Android.

The idea

Most note apps assume you'll sit down and type. But ideas don't wait for a keyboard. Thinkora is built around speed of capture:

🎤 Voice capture — speak, and it becomes a note or task instantly
🔥 Streaks — a light habit loop to keep you showing up daily
☀️ Morning Brew — a generated daily brief so you start focused
🗓️ Smart calendar — with holidays baked in
✅ Notes, tasks, reminders, rich text, folders & tags
The stack

Built with React Native, with platform-specific work on Android for the rich editor, voice, and notifications (Notifee). State lives in a context layer with local persistence, organized in a clean core / services / components / screens structure.

Try it / tell me what breaks

It's live on Android. I'd love feedback from other devs — especially on the capture flow:

What's your current setup for capturing ideas on the go?

The features I refused to build into my productivity app — and why

Muhammad Aamir Yameen — Thu, 04 Jun 2026 08:45:31 +0000

When I started building Thinkora — my all-in-one Android productivity app — almost every piece of advice I got was the same: add social features.

"Add streak sharing."
"Add a public profile."
"Add a leaderboard for habits."
"Add a feed."

The argument was always engagement. Social features make users return more often. They give the product a viral coefficient. They turn the user's progress into your distribution.

I shipped Thinkora with zero of them. Here's the reasoning, and the engineering trade-offs that came with it.

The decision rule

Every feature in Thinkora has to answer one question: does this make the user more honest with themselves, or less?

Social features fail that test almost without exception. The moment a user's habit log becomes visible to others, the log stops measuring the user's behavior and starts measuring the user's self-presentation. People skip the bad days in the journal. They round up the workout. They quietly remove the failed goal.

This is fine in the abstract. It is fatal in a tool whose value depends on accurate self-tracking.

What this changed in the architecture

Once you commit to no social features, a lot of engineering becomes simpler:

No user identity service. The app does not require an account to function. There is no concept of "your user ID" being meaningful to anyone but you.
No content moderation. Nothing the user writes is ever shown to another user, so there's nothing to moderate.
No follow graph. No notifications service tied to other users. No reporting flows.
No public CDN for user content. Notes, habit logs, mood entries — none of it leaves the device unless the user opts into cloud sync, and even then it's encrypted and only readable by them.
The local-first architecture and the no-social-features stance reinforce each other. Each one is harder to walk back once it's wired into the foundation, which is exactly the point — values that live in code, not in policy, survive a business pivot.

The trade-off I knowingly accepted

Without social features, growth is slower. There is no viral loop. Every user has to be earned individually through word of mouth, content, and trust.

I made my peace with that. The kind of user who would have arrived through a streak-share notification was never going to be the kind of user this app is for.

The kind of user it's for found us because they were tired of being performed at by their own tools.

Why I built the evening reflection feature before the morning planner

Muhammad Aamir Yameen — Wed, 03 Jun 2026 07:02:25 +0000

When I was planning the feature set for Thinkora — my all-in-one Android productivity app — I made a counter-intuitive call early on: I built the evening reflection screen before I built the morning planner.

Every competitor leads with the morning. Day starts with a dashboard, a planner, a "what's important today" prompt. The morning is loud, feature-rich, dopamine-coded.

The evening, in almost every productivity app, is empty. The day ends in the same dashboard it started in. No closure. No review. Nothing.

This always felt backwards to me. So I tested a hypothesis.

The hypothesis

Users who reflect at night retain more of the next day's plan than users who plan harder in the morning.

This isn't a controlled study — it's a pattern from beta testing. But the signal was strong enough to commit to: testers who used the evening reflection screen for 7+ days showed measurably higher task-completion rates the following week, regardless of how much time they spent planning in the morning.

Reflection was the leading indicator. Planning was the lagging one.

The implementation: Daily Pulse

Daily Pulse is deliberately tiny. Three free-text fields:

What worked today?
What didn't?
What do you want to carry into tomorrow?
That's it. No mood slider. No streak counter. No required tags. No notification if you skip it. No "you broke your 14-day chain" red badge.

The implementation rules I locked in early:

It must be skippable without guilt. The day a productivity app starts shaming you for missing reflection is the day reflection becomes performative.
It must take under 90 seconds. If it takes longer, you stop doing it on hard days — which are the days it matters most.
It must surface answer #3 in the next morning's Morning Brew. Reflection without continuity is journaling. Reflection that influences tomorrow is a system.
The engineering bit

Daily Pulse writes to a local-first WatermelonDB table. The previous night's "carry forward" is read by Morning Brew on the next sunrise (using device local time, not server time — important for travelers).

There is no server roundtrip. There is no analytics event on the content. The only telemetry I collect is "feature opened" and "feature submitted" — never what was written.

Why this matters past my app

If you're building anything habit-shaped, the reflex is to over-engineer the entry point: more inputs, more taps, more configurability. The actual leverage is almost always in shrinking the loop and making the next-day continuity tight.

People don't stick to systems because the system is comprehensive. They stick because the system feels light on a bad day.

Daily Pulse is the lightest thing in Thinkora. It's also one of the most-retained.

The feature in my app that nobody asked for — and everyone uses

Muhammad Aamir Yameen — Mon, 01 Jun 2026 08:08:12 +0000

I shipped a feature in Thinkora that no user ever requested. It's now one of the top three most-used features in the app.

It's called Idea Resurfacing.

The thesis is simple: most note-taking apps optimize for capture and search. Almost none optimize for re-discovery. But the failure mode people actually hit isn't "I can't find my note" — it's "I forgot I had a note." Those are different problems with different solutions.

How it works under the hood:

Notes are tagged automatically (via existing manual tags + lightweight on-device keyword extraction).
A daily job scores each older note against the user's recent activity (recent tags, recent searches, recent task topics).
Notes above a threshold surface as a small card in Morning Brew with: "You wrote this 7 months ago — feels related to today."
Design decisions worth flagging:

This runs on-device. Notes never leave the device for resurfacing. (Local-first is non-negotiable for journal-style content.)
It is not a push notification. It is opt-in surfacing inside an existing screen. The cost of a wrong suggestion should be near-zero — closing a card, not silencing a notification.
There is a "not relevant" tap that down-weights similar suggestions. No model training, just per-user score decay.
Result: usage that quietly beats features I spent 5x as long building. The lesson I keep relearning — the best features address problems users haven't named yet.

I built one Android app to replace the five I was juggling. Here's what's inside Thinkora.

Muhammad Aamir Yameen — Mon, 25 May 2026 07:44:01 +0000

Notes, tasks, habits, mood and AI insights — local-first, no subscription wall, designed for people who are tired of productivity theater.

The 5-app problem

A year ago, my productivity system had quietly become its own full-time job. Notes lived in Notion. Tasks lived in Todoist. Habits in Habitica. Mood in Daylio. My calendar talked to none of them. Every Sunday night I spent 40 minutes copy-pasting between tools just so Monday felt manageable — and by Wednesday the whole stack was out of sync again. I didn't have a productivity problem. I had a productivity-app problem. So I started building the app I actually wanted: one calm Android app that respects my attention, works offline, and doesn't charge 90 dollars a year to track a habit. That app is Thinkora.

What I wanted instead

Three rules, written on a sticky note above my desk while I built it. One: one app, one home screen. If I need a second app to make the first one useful, I've already lost. Two: local-first, private by default. My journal is not a growth metric. Three: no subscription wall on the basics. Streaks and notes are not a premium feature. Everything in Thinkora is built around those three rules.

The feature set, told as a day

Morning — Morning Brew and Today Card. You open the app and get a one-screen briefing: weather, what's actually due today, the habits you're trying to hold, and a gentle quote. No 14-widget dashboard. Just here's today, in one glance.

Throughout the day — capture and plan. Notes with rich text, voice memos, sketches, document scanning (with OCR) and PDF export. Tasks with sub-tasks, tags, attachments, reminders and recurring schedules. Eisenhower matrix and time-blocking to turn a wish-list into a real day. Pomodoro timer and built-in time tracking when you actually need to sit down and do the thing.

Evening — Daily Pulse, habits and mood. Habit tracker with habit stacks (after coffee, meditate), streaks, badges and streak rewards. Mood journal with AI-powered insights (Gemini) — patterns surfaced gently, not gamified. Daily Pulse to close the day honestly: what worked, what didn't, what to carry forward.

Weekly and monthly — reports, recap, share cards. A calendar heatmap that finally makes showing up visible. Goals with milestones and shareable progress cards. A Year-in-Review recap on your Thinkora birthday — because you deserve to see your year.

The AI layer (and why it's opt-in)

Thinkora uses Google's Gemini for the AI features. Mood insights — pattern detection across your journal, not just a chart. Smart timing — surfacing reminders when you're statistically most likely to act on them. Idea resurfacing — old notes brought back at the right moment instead of dying in a list. All of it is opt-in. You can bring your own API key, use Thinkora AI, or turn it off completely. The app works fully without AI; the AI just makes it quieter and smarter.

The boring-but-important stuff

Local-first storage (WatermelonDB). The app works fully offline. Your content lives on your device. Optional cloud sync for when you want it, off by default. App lock and biometric support. No selling of content. No analytics on your notes. Just anonymous, aggregated usage to fix bugs. Free with a single banner ad — no paywall on streaks, notes, tasks, habits or mood.

What's next

The next few releases focus on deeper widgets and persistent tray controls, more habit-stack templates, shared lists for couples or small teams, and calmer notifications (smart batching, focus windows). I publish what I'm working on as I go. If you want to shape it, the fastest way is to use it and tell me what's missing.

The 5-app problem
A year ago, my "productivity system" had quietly become its own full-time job.

Notes lived in Notion. Tasks lived in Todoist. Habits in Habitica. Mood in Daylio. My calendar talked to none of them. Every Sunday night I'd spend 40 minutes copy-pasting between tools just so Monday felt manageable — and by Wednesday the whole stack was out of sync again.

How I built a free productivity app that replaces 5 subscriptions

Muhammad Aamir Yameen — Sun, 10 May 2026 09:52:02 +0000

I was paying $42/month for productivity apps. Notion, Todoist, Habitica,
Daylio, Forest. Five different cloud accounts, five separate UI patterns,
and not one of them knew when Eid was.

So I built Thinkora — a free, on-device productivity app that combines
all five into a single daily loop. This is what I learned building it
and what's working in production.
