Föli is a free Android app developed by iQ Payments that simplifies the process of buying and using public transport tickets in the Turku region. The app offers a range of ticket options, including single, day, and multi-tickets for adults and children, as well as long-distance and other cities' local bus tickets. It also provides the option to top up travel cards such as Season, Value, and Tupla.

One of the standout features of Föli is its "Best Price Ticket" option, which calculates the cheapest fare based on your travel distance. The app also offers a mobile season ticket for adults, which eliminates the need for a physical travel card. Additionally, Föli provides current traffic announcements and news, as well as route planning and timetables. The app can be used without registering an account, but for full access to all features and payment methods, users can sign in with Google or create a user account.
