The app uses the Repository pattern to abstract data sources:
- Fetches data from Open-Meteo API
- Caches data in Room database
- Provides a single source of truth
WorkManager ensures weather data is updated every 6 hours:
- Respects device battery optimization
- Works even if the app is closed
- Requires network connectivity
