Built with Expo, Redux Toolkit, React Navigation, Axios, react-native-maps, and Firebase Realtime Database. The app runs in **demo mode** until you add Firebase credentials. Simulated buses still move on the map so you can try Search, Live Map, and bus details without a backend. ## Run the app ```bash npm install npx expo start ``` Scan the QR code with **Expo Go SDK 54** (this project targets SDK 54). Google Maps tiles on Android need `EXPO_PUBLIC_GOOGLE_MAPS_API_KEY`. iOS Expo Go uses Apple Maps; Google Maps on iOS needs a development build. ## Optional: live Firebase feed 1. Copy `.env.example` to `.env` and fill in your Firebase web config plus a Google Maps API key. 2. In Firebase, enable Realtime Database. For local development only, rules can be: ```json { "rules": { ".read": true, ".write": true } } ``` Do not ship open rules to production. 3. Seed routes, then start the GPS simulator: ```bash npm run sim:seed npm run sim:run ``` The simulator updates 4 buses every 4 seconds on two corridors: - **107 Remera – Masaka** via Mulindi - **305 Kimironko – Nyabugogo** via Amahoro Stadium, Chez Lando, and Kacyiru ## Try it Search **Remera → Masaka** or **Kimironko → Nyabugogo**. Open Live Map, tap a bus marker, and (optional) watch a bus for a local notification when it is about 5 minutes from your stop. ETA v1 is straight-line (haversine) distance divided by speed (~25 km/h if missing). Route-polyline distance is left for v2.
