I am living in Milan as an expat. This is the only app I use to get around the city on the public transport system. It has maps, stops and routes ( very important because with bus in Italy, you dont usually find he return station just across the street, sometimes it can be 3 blocks away as with bus 61 in the center) for all, bus tram and metro. It even has GPS Tracking. Absolutely fantastic.
