The app tracks your location. All you have to do is enter your desired destination in the "Search" tab of the app and choose the one that suits you best from the proposed connections.
If you click "Buy ticket" in the "Bookings" tab of the KVV.mobil app, you will be directed to the ticket selection page where you can adjust the ticket type, the area of validity and the starting point.
If you have a BahnCard, you can activate the ticket discount in the booking process using a toggle.
Immediately after the purchase, you will receive your ticket directly in the app.
