Öffi-Radar
Uses GPS to show which bus or train you are on, which departures are near you and when you will arrive.
Öffi-Radar answers many questions when the display is out of order again or the announcement is missing: Which line am I actually on? When will I arrive? Where am I? Do I have to rush to my connection, or is it too late anyway?
The app runs directly in your browser and only needs your location. There is nothing to install, but you can add it to your home screen.
Open it directly on your phone and do not forget to allow location access:
Features
All modes of transport in one app
Bus, tram, metro, S-Bahn, regional train and intercity in the same design. The filters at the top keep things clear.
Recognises your line
From the GPS points of your ride, the app works out your direction of travel and boarding point and shows the matching line. For unambiguous lines, the padlock 🔒 locks automatically.
Real-time, timetable or calculated
Times for the next stops come from real-time and timetable data. On the move, the app calculates its own estimate from your speed and route, so delays are accurate right away. You can switch the display mode at any time.
Connections at a glance
Tap an arrival time to see right away which departures there are at that stop and nearby. That way you know whether to hurry or whether the connection is gone anyway.
Useful even without a ride
Without tracking, the app shows the stops around you with the next departures and the walk to get there. You can also pick another stop or time, for example "When does my bus leave tomorrow morning?"
Install, share, 15 languages
