kav
An ad-free, account-free transit app for Android. The map and timetable are on the phone, so stops, lines and the map work with no signal.

Could you build this?
Partial While an offline mobile transit UI is straightforward to build, packaging and indexing massive offline GTFS transit schedules and vector map data (like OSM) for performant on-device routing without server connectivity requires non-trivial offline graph algorithms.
What it would actually take: The app needs an Android stack (Kotlin/Jetpack Compose or Flutter) with embedded MapLibre/Mapbox for offline vector tiles (MBTiles), combined with an embedded SQLite/Spatialite database or custom graph structure for GTFS transit data. The hardest technical challenge is implementing efficient offline transit routing algorithms (such as Connection Scan Algorithm or RAPTOR) and graph compression directly on a constrained mobile device. Building this requires expertise in offline GIS systems, transit routing graph optimizations, and Android memory management.
