From Giacomo Balli:
Finding a cab in Florence has never been this easy!In many cities, you can simply spot a cab, hail and it pulls over for you (just think of Madrid or New York City).In Florence instead, you have either call or go to one of the designated cab stands. This might obviously be a tough situation for anyone who's not local.Everything is solved thanks to this simple app. The database with all the spots where cabs "wait" is already bundled. Thanks to the GPS built-in your iDevice, it will automatically display the closest one to you on a map along with hours of service and details to get there.If you don't feel like walking you also have the numbers to call a taxi to come pick you up wherever you are.There is no way of making it easier!
