Raise Codey while you learn to code.
Pomodoro sessions, coding challenges, arcade games and pet-care systems in a local-first Android app.
English · Español
Code Tamagotchi turns programming practice into a pet-care loop. Study with Pomodoro, solve coding challenges, earn XP and Bytes, then use those rewards to keep Codey healthy, rested and evolving.
The app is built for Android with Kotlin, Jetpack Compose, Room, DataStore, Koin and WorkManager, with Codey rendered procedurally instead of imported as sprite PNGs.
The project screenshots live in capturas_de_pantalla/ and are shown here in their folder order.

The long README content was split into focused docs:
| Guide | Use it for |
|---|---|
| Getting Started | Build, install and run commands. |
| Gameplay | Pet loop, economy, themes and rewards. |
| Architecture | Stack, package map and app wiring. |
| Persistence | Room, migrations and DataStore. |
| Rendering | Codey, themes and widget rendering. |
| Testing | Unit, Robolectric, lint and screenshot tests. |
| Localization | Spanish/English resources and content. |
| Roadmap | Shipped features and next ideas. |
The older Spanish full reference is still available in documentacion.md.
The easiest contribution is adding or improving learning content:
- Add challenges for languages with smaller banks.
- Improve explanations in Codey's voice.
- Keep Spanish and English challenge entries synchronized.
- Report UI bugs with screenshots and device details.
- Suggest themes, wardrobe items or study rewards.
