The app guides you through the urban jungle with step-by-step navigation, tells you when to get off or change trains, and gives you smart tips on your route. For example, the app shows you if you need to get on the train from the front or back, to shorten the transfer time later. In a foreign city, significant minutes and a lot of running are saved at the train station.
If you wish, you can also set up daily commutes and receive push notifications about route updates. The only drawback: so far, the application in Germany is only available in large cities and large parts of the Ruhr area.
