TAD Île-de-France Mobilités is an on-demand transport system that operates only on reservation, complementing other existing lines such as buses and trains. This service is funded and implemented by Île-de-France Mobilités and currently covers five sectors. The easy-to-use application allows users to book their trips in real-time, up to a month in advance, and consecutively for 30 days.

The TAD Île-de-France Mobilités app has several features that make it convenient for users. Users can learn about the service, book their trips to get around all the stops, indicate their favorite journeys and save them in the app, manage their reservations by modifying and/or canceling them in real-time, and evaluate their trip. By booking their trips as early as possible, users can have a maximum of proposals corresponding to their research and therefore a larger choice to make the reservation of their choice.

Overall, TAD Île-de-France Mobilités is a dynamic and flexible transport system that offers users a convenient and efficient way to travel around the five sectors it currently covers.
