A to B is the fastest way to see Danish transit schedules. The app includes schedules for busses, trains, and ferries for all of Denmark so it's always fast and works offline. The schedules are automatically updated when you're online and they're the same ones used by rejseplanen.dk.
See departures between two stops or all departures from a particular stop. If you're at a stop the app automatically shows the next departures. Save bookmarks for the schedules you use most often so you can access them with a single click – and because they're stored directly on the phone you can see them right away, you don't have to wait for them to be fetched over the internet.
Note: A to B is a new app so there may be bugs initially. But it's free so give it a try anyway!
