This is a personal time tracking app that I created for myself. More background at my blog and Hacker News.
You can try it out by installing an APK from the releases page. Please open a GitHub issue if you're having problems.
All data is saved to a chronofile.tsv file on your device. This app is 100% offline and never accesses the internet - no ads, no telemetry, nothing.
I used this project to learn Kotlin and relearn Android development before I began work on the Duolingo app, which is now 100% Kotlin!
