An Android app for cyclists who plan one-way bike routes and need to take a train home.
Import your GPX route, and the app discovers train stations along your path. When you're ready to head home, it shows the best options: which station to ride to, how long you'll wait, and when you'll arrive home.
The app currently uses Deutsche Bahn (DB) as the default transit provider via the public-transport-enabler library. DB covers German domestic and many international connections. The library supports 50+ European transit providers — adding a provider selection is planned for future versions.
- Import GPX routes (share from Komoot or any cycling app)
- Automatic discovery of train stations along your route
- "Take me home" — see upcoming stations with cycling time, wait time, and connections
- Search for nearby stations anywhere on the map
- Detailed connection info with intermediate stops and changes
- Navigate to any station via your preferred map app
- Download map tiles for offline use
- Configurable transport types (Deutschlandticket: regional trains, S-Bahn, U-Bahn, tram, bus)
- Optional ICE/IC/EC connections
- Configurable minimum wait buffer and maximum wait time filter
