# FightRateRN

React Native Community CLI rebuild of FightRate. This app is **bare React Native only** and does not use Expo.

## Visual source of truth

The app follows the selected FightRate direction:

- `../FIGHTRATE_DESIGN_SYSTEM.md`
- Direction: `01 — Corner Instrument`

Do not reuse the deprecated Combat Lab/card-heavy direction.

## Current slice

Implemented in this first slice:

- Corner Instrument app shell.
- Continuous capture-first home screen.
- History, Sensor, and Insights screens.
- Centralized design tokens in `src/theme`.
- Reusable UI components in `src/components`.
- No Expo dependencies.
- Android `applicationId` aligned to `com.healthtracking.fightrate`.

Not implemented yet:

- Real BLE Magene H003 integration.
- SQLite/local persistence.
- Real timestamped workout chart data.
- Navigation library.

## Commands

```bash
npm install
npm run typecheck
npm run lint
npm test -- --runInBand
```

Run Metro:

```bash
npm run start
```

Run Android on a device/emulator:

```bash
npm run android
```

Build Android debug APK:

```bash
cd android
./gradlew assembleDebug
```

If Gradle reports `No Java compiler found`, point `JAVA_HOME` to Android Studio JBR:

```bash
export JAVA_HOME="/c/Users/Evandro/AppData/Local/Programs/Android Studio/jbr"
export PATH="$JAVA_HOME/bin:$PATH"
cd android
./gradlew assembleDebug
```

If React Native autolinking keeps a stale package after renaming Android package paths,
clean generated Gradle caches before rebuilding:

```bash
cd ..
rm -rf android/.gradle android/app/build android/build .gradle
cd android
./gradlew assembleDebug
```

Debug APK output:

```text
android/app/build/outputs/apk/debug/app-debug.apk
```
