Bimba is an app which shows public transport timetables in multiple localities—cities, towns, regions, countries. Currently only Android version is available and choice of localities is limited.

But Bumba is also the whole system comprising a server, a client app, and the protocol. Currently, the only server implementation is szczanieckiej, the only client app is czwek. The protocol combining all parts is TRAFFIC.

Future of the project is described in the roadmap.
