I came down here to visit the military base. I live in Hamburg, Germany. I was on the wrong train and I could not find a schedule or a good map of the trains and routes to find my way back to the place at Niederrad where I had parked my car. I downloaded this app on the desperate hope it would help me find my way back to the Hauptbahnhof and then to the train station where my car was. The app did not give times and the map was hard to read and unhelpful. Eventually my wife who is German found the correct route and train back to Hauptbahnhof and two lines that went to where I parked, but the app had no times so I did not know which one would be there first or was better to take.
