Nidbuss

Nidbuss is an app for displaying real time data for public transport in Norway. From version 3.0 Nidbuss uses data from the national Entur service, which now makes it possible to support over 50 000 stop places and multiple transport types all across the country.

Nidbuss is especially useful for commuters. Just add the stop places you usually travel from, then filter out unwanted routes, so only the ones you are using are visible.
