I reckon this app by far the best one in terms of dealing with your journeys when you are in unfamiliar cities.When I was in London, I was using this app and I did get the most the out of it during my stay there.I am really happy to hear that its now available in my hometown, too which is Istanbul.I remember that I had requested it for my hometown.They have released the beta version recently.Thank you guys! We cannot really thank you enough! Keep up the good work!!!
