HabitKit

HabitKit is a habit tracking app designed to help users form new habits or break old ones. It allows users to track their progress using beautiful tile-based grid charts on a customizable dashboard. The app also offers features like habit creation, a calendar for managing past completions, an archive for temporarily removing habits from the dashboard, and import/export functionality for data backup. Additionally, HabitKit is privacy-focused, as it does not require sign-in and keeps all data on the user's phone without using any external servers or cloud services.

I'm Sebastian, 30 years old and from Germany. After finishing university, I spent three years working as a Software Engineer. But I always had this dream of starting a small company to create and release my very own apps. So, I took a leap of faith, quit my job for a year, and started building those apps. My first one, a workout tracking app called Liftbear, didn't quite take off, but I learned a ton in the process. Then came my second app, HabitKit, which turned out to be way more popular! I'm super excited with how it's doing right now.

I came up with HabitKit because I wanted to improve my life and create some healthy habits. So, I got to work on the app and while building it I began tracking my progress in various aspects of my life, like weightlifting, running, reading, and a bunch of mental health-related activities. The cool grid-based visualization of my progress in the app totally made a difference for me, and I just knew I had to share this opportunity with others.

So far, I've managed to publish two apps which have brought in a total revenue of ~$6k. With a monthly recurring revenue of ~$500, I've seen more than 12k app downloads, showing that things are moving in the right direction. Plus, I've managed to build a community on Twitter, with 3.7k followers and counting!

Since my project ideas centered around mobile user experiences, I naturally gravitated towards Flutter. I had a blast with the developer experience, and it let me quickly build apps for both iOS and Android using just one codebase. Plus, the package ecosystem is super solid, and there are plenty of great learning resources out there. Without a doubt, I'd pick Flutter again for any future mobile app projects.

As I stated before, I would definitely choose Flutter over another framework again. I rarely encountered problems while developing with it. I experienced some kind of lag and animation jank on iOS devices, but there were some great resources available on how to counter this problems. I would wish that the Flutter team would focus their ongoing efforts on the mobile platforms and not spread out too much (like supporting web for example). But all in all, it's a great framework!
