Yes, you can use the SBB Mobile app without a SwissPass in 2026, but your experience will be slightly different. The app allows you to create a "guest" login or a standard account where you can purchase individual point-to-point tickets, Saver Day Passes, and "Supersaver" tickets using a credit card or Apple Pay. You do not need the physical red SwissPass card to show your ticket; the app generates a QR code that conductors scan directly from your screen. However, having a SwissPass login (even without the physical card) is highly recommended because it saves your personal data and travel preferences, making the "EasyRide" check-in/check-out feature much smoother. If you are a tourist, you can use the SBB app to display your Swiss Travel Pass or to purchase the "Half Fare Card" which is then stored digitally in the app. The only "catch" is that for certain discounted tickets, you must be able to prove your identity, so you should always carry your physical passport alongside your digital app-based ticket. The SBB app remains the gold standard for European transit apps in 2026, offering real-time platform changes and "walking speed" navigation for every station in Switzerland.
