A lightweight, privacy-focused Android app for checking real-time transit data.
Built with OSMDroid, it clusters nearby stops on a map and shows live predictions when you tap on a stop.
Key Features
- Real-time bus arrivals (currently for the DC area only, powered by WMATA API)
- Clustered map of stops using open-source tiles (no Google Maps)
- Colorblind-friendly marker icons
- Minimal permissions (no tracking or accounts)
Tech Stack
- Kotlin
- OSMDroid for map rendering
- osmbonuspack for clustering
- Retrofit for WMATA API calls
Current Status
- Feature-complete MVP
- No ads, no analytics
- Clusters and predictions working
- Preparing for v0.1 release
Planned Enhancements
- Tap-to-zoom refinement on clusters
- Save last viewed map region
- Save favorite stops
- Optional fallback to schedule data if real-time API fails
- Screen-reader-friendly list view
- Localizations to common DC Area languages and others as requested
Privacy This app does not collect or transmit any personal data. It does not use your location at all - map position is entirely user-selected.
