Troms Billett (ny) is a free mobile app developed by Troms Fylkestrafikk that allows you to purchase tickets before boarding public transport in Tromsø. The app is valid for buses, express boats, and ferries provided by Troms Fylkestrafikk.

One of the key features of Troms Billett is that it automatically suggests a ticket for the zone you are in, based on your exact position in the foreground, which is why it requests access permission to your device's location services. However, if you prefer to turn off location services, you can still manually state where the ticket should apply.

The app also has other useful features, such as the ability to update period tickets with control codes and today's image, purchase tickets and upgrades via a foreground service, receive notifications for available tickets, and confirm purchase of tickets using biometric hardware. Troms Billett also allows you to view network connections, which is useful for immediate error messages if the network is down.

Overall, Troms Billett is a convenient and reliable way to buy tickets for public transport in Tromsø.
