The SBB Mobile app remains the undisputed "best" and official app for all public transport in Switzerland in 2026. It covers not just trains, but also buses, trams, boats, and even some cable cars. The app's standout feature is "EasyRide," which allows you to "check in" when you board and "check out" when you arrive; the app then calculates the cheapest possible fare for your journey automatically. It also integrates your SwissPass digital travelcards and offers "Supersaver" tickets for those booking in advance. For international connections into Switzerland, many travelers also use Trainline, but for the "last mile" accuracy of platform changes and real-time delay notifications within the Swiss network, the SBB app is the gold standard for residents and tourists alike.
