The app allows you to:
- automatically center the map on the user's current location
- display all stops on the map
- search for a line and stop
- display upcoming departures based on the current bus location
- display upcoming departures based on timetables (if the bus doesn't transmit its location or the service isn't running yet)
- add stops to favorites
- set a shortcut to a favorite stop on your phone's desktop
- other

WhenBus was created by goEuropa, a Poznań-based company that creates solutions for public transport passengers exclusively based on free and open source code, thus guaranteeing application development and providing support from a community focused on open-source projects.
The OneBusAway software used in WhenBus is used in implementations in countries such as the United States and Finland. goEuropa participated in the development and configuration of this system.
