This app provides information about public transportation routes in Rome and other cities worldwide. Besides, it’s the only one recommended by the local transportation authority (ATAC).
When it comes to buses and trams, the app can provide real-time information (based on GPS data) on vehicle arrivals at any stop. For the subway, it provides estimated arrival times of the next metro trains.
Moovit is ideal for planning trips using any type of public transportation, including regional lines operated by Trenitalia. It can be used directly in web browsers, without the need to download the app. However, it is recommended to install it anyway for a significantly better user experience.
