Habit-tracking app with GitHub-style grids
Hi HN! After ~9 months of development, I published my very first app to the App Store. It's called Checker, a habit/goal-tracking app that uses GitHub-style calendar grids to visualize your progress. It's relatively simple for now but I'll be adding quite a few features in the coming months, like board color themes, Apple Health integration, more widget styles, etc. Hope you give it a try, and if you do, please let me know if you have any feedback.
In plain words
Checker is a habit and goal-tracking app that displays progress using GitHub-style calendar grids. Users can visualize their tracking patterns and consistency at a glance. The app is designed for anyone building or maintaining habits and currently offers basic tracking functionality. Planned features include customizable board color themes, Apple Health integration, and additional widget styles.

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
