Mentrick
- Android app
- On Google Play
20 mind games for one phone: solo brain training, party games where you pass the phone around and magic tricks to impress your friends. It's free, has no ads and needs no account.
What I built
- I rebuilt the whole app for version 6, with a new design system, and doubled the games from 10 to 20.
- Version 5 users update in place: DataStore keys, game IDs and the launcher alias still match, and a unit test reads a real version 5 DataStore file.
- The app is split into 33 Gradle modules, one feature module per game, with convention plugins in build-logic.
- Baseline Profiles ship in release builds, and a cold-start Macrobenchmark compares startup with and without them.
- Play Games Services with 25 achievements and 7 leaderboards.
- Per-app language for English, French and Arabic.
