Saarfahrplan is the official app of the Saarland transport association, offering a mobile routing platform and an integrated saarVV online shop for convenient purchase of mobile tickets. It provides real-time routing information for stops, addresses, points of interest, and current locations. Users can purchase specific tickets online, view departures and arrivals for stops, and access a map displaying stops. The app also offers traffic information, connection alarms for updates, and the option to add connections to calendars or share them via email or SMS.

Saarfahrplan requires access to device location services, navigation, and calendar functions for planned rides. Users can adjust privacy settings within the app. A live internet connection is necessary for routing information, and while personal data isn't sent to central servers, timetable accuracy isn't guaranteed.
