This was the best $0.99 Ive ever spent. It saved me so much time in Paris as it made it extremely easy and fast to use the Metro. There is just one thing I hope the developers will do. When the route is displayed (in the list format) please add the name of the stop at the end of the line so that in the metro station it is easier to know which train to go to. For example, the yellow line 1 ends at either La Defense or Chateau de Vincennes. You need to know which one of these is the end of the route you are travelling in order to get on the right train. With this additional info it would be perfect!
