GPXIT

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.

Transit Provider

Stations and connections come from Deutsche Bahn (DB) via the public-transport-enabler library. DB covers German domestic and many international connections. Where DB's coverage is weak, the app also asks the national provider for that place — Rejseplanen (Denmark), Resrobot (Sweden) or Traveline (Great Britain) — and merges the results. Which providers to ask is decided from coverage data by KPublicTransport.

Optionally (Settings → Transit data), the community-run Transitous service adds local transport in many more countries, e.g. trams and buses in France.

POI data

Shops, drinking water, toilets and bike repair come from OpenStreetMap, as one SQLite file per country or region (37 of them, where the transit providers have coverage). The Build POI Dataset workflow rebuilds them monthly and publishes them in the poi-data release; the app downloads the countries picked in Settings → Map & data and offers the missing ones when a route enters another country. Opening hours are evaluated on the device, including public and school holidays of the region.

Features

• 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
• Shops, bakeries, drinking water, toilets and bike repair along your route, with opening hours — offline, for the countries you choose
• 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

Building

Prerequisites

The project uses a Nix flake for a reproducible dev environment:

nix develop

Or if you have direnv: entering the directory auto-activates the shell.

The flake provides: JDK 21, Gradle, Android SDK (platform 37.0, build-tools 37.0.0).

Build variants

Variant	Description
fossDebug / fossRelease	FOSS build — uses Android LocationManager, no Google Play Services. F-Droid compatible.
fullDebug / fullRelease	Full build — uses Google Play Services for better location accuracy.

./gradlew assembleFossDebug       # FOSS debug APK
./gradlew assembleFossRelease     # FOSS release APK
./gradlew assembleFullDebug       # Full debug APK
./gradlew assembleFullRelease     # Full release APK

Privacy

• No tracking, no analytics, no accounts
• All data stays on your device
• Location is used only to show your position on the map
• Internet is used for map tiles (OpenStreetMap), transit queries (Deutsche Bahn; Rejseplanen, Resrobot or Traveline for places they cover; Transitous only if enabled) and downloading the offline POI data (GitHub)
