Bus / train schedules at your fingertips and wrist! (Android+Wear operating system, both apps are in BETA) This app allows you to consult line schedules, save favorite lines, find the nearest stops and navigate to any line with maps.
You can also search for any stop in the selected city and find out which lines pass through a stop, in addition to the first available time and the direction of the trip.

Requires an Internet connection.

Currently it only supports static data (GTFS static). Realtime data (GTFS realtime) is made available by transport companies only for some cities and is being implemented.

The RSS feed on line alerts is only available for some cities since they have not been made public by all transport companies.
