I Used Google's Gemini CLI to Build My App, and It Blew My Mind

I’ve been a software developer for a while now, and I’ve always been fascinated by the process of building something from scratch. But let’s be honest, it can be a real grind. There are days when you’re just staring at your screen, trying to figure out why your code isn’t working. And then there are the tedious tasks, like setting up boilerplate code or trying to understand a new codebase.

That’s when I decided to try something new. I had been hearing a lot about Google’s new Gemini CLI, and I was curious to see if it could help me with my project. I have to say, I was blown away. I don't need Claude, Cursor, or any of that other noise anymore (at least with no cost :P).

The Gemini CLI is like having a super-intelligent assistant right in your terminal. I started by giving it access to my project and I ask it questions in plain English, and I was able to build DetoxEar in a fraction of the time it would have taken me otherwise. I was able to focus on the creative aspects of the app, like the user interface and the user experience, while the Gemini CLI handled the tedious tasks.

So, what is DetoxEar?

It's a mobile app for iOS and Android that helps you be more mindful of your headphone usage. It runs in the background, and when you've had your headphones on for too long, it sends you a gentle reminder to take a break. It also has a dashboard where you can see your daily and weekly usage stats, so you can get a better understanding of your listening habits.

I built DetoxEar because I was worried about my own hearing. I was spending hours every day with my
headphones on, and I knew it wasn't good for me. I wanted an app that would help me be more aware of my listening habits, and I couldn't find anything that did exactly what I wanted. So, I decided to build it myself.

How Gemini Helped Me Build It

The Gemini CLI was instrumental in the development of DetoxEar. For example, I needed to set up a local database to store the user's session data. I had never worked with SQLite in a NativeScript app before, so wasn't sure where to start. I asked the Gemini CLI, and it generated the entire database.service.ts file for me. It even included the code for creating the tables, inserting data, and querying the data.

I was also able to use the Gemini CLI to help me with the UI. I wanted to create a dashboard that would show the user their daily and weekly usage stats. I asked the Gemini CLI to create a chart that would visualize the data, and it generated the code for the chart using the @nativescript-community/ui-chart library.

The Future of App Development

I’m convinced that AI is the future of app development. Tools like the Gemini CLI are going to make it possible for anyone to build an app, regardless of their technical skills. It’s going to level the playing field and lead to a new wave of innovation.

If you’re a developer, I highly recommend checking out the Gemini CLI. It’s still in its early days, but it’s already incredibly powerful. And if you’re looking for a way to be more mindful of your headphone usage, be sure to check out DetoxEar.
