Transito

Transito is a FOSS data-provider-agnostic public transportation app that let's you route between locations using openly available public GTFS feeds. The app lets you check departure times for stops & perform routing calculations offline / right on your phone (e.g. no network calls once data is initially fetched). See details at the project respository here and the app userguide here .

Provides routing results in both step & map view formats

Browse stops from GTFS feeds data, see departure, and select stops to route to/from (offline)

Allows searching for POIs via Nominatim (requires network connection)

Allows switching between using different individual GTFS feeds or using multiple feeds in combination

Simple configuration system & algorithm tunables
