T-mobilitat is the official application of the Barcelona ATM for public transport travel and validation. This app allows users to buy and upload transport tickets, plan their trips with the best possible routes, and check the status of the network in real-time. It also provides alerts and notifications of possible alterations or incidents in the network, thanks to the integration of the application with the transport control center.

One of the unique features of this app is that users with a mobile phone with NFC technology can use their phone as a virtual card to access public transport without the need for a physical card. Additionally, users can buy their transport tickets and load them on their T-Mobility Card just by bringing it to their phone. Users can also check the status of their card and their titles and manage their data and profile.
