Travel & navigation apps on iPhone Duo
Of the 19 popular travel & navigation apps we track on the US App Store, 7 are confirmed to fill iPhone Duo’s inner display, including Lyft, United Airlines and Google Maps. 12 still show black bars or unused space, including Uber, Expedia and Waze Navigation & Live Traffic.
Maps on a larger, squarer screen show far more context. Ride-hailing and booking apps typically only need the outer display, so black bars on the inner display matter less here.

Questions
Which travel & navigation apps work on iPhone Duo?
All of them run on iPhone Duo. Of the 19 we track, 7 are confirmed to use the whole inner display: Lyft, United Airlines, Google Maps, Booking.com, Airbnb and Flighty.
Do travel & navigation apps have black bars on iPhone Duo?
12 of the 19 we track show black bars or unused space today, including Uber, Expedia, Waze Navigation & Live Traffic, Lime and onX Hunt. Apps built with the iOS 26 SDK or earlier run in a phone-sized window on the inner display until the developer ships an update built with the iOS 27.1 SDK. On the outer display they look normal.
Do travel & navigation apps work on iPhone Duo’s outer display?
Yes. The 5.4-inch outer display works like a regular iPhone screen, so every app runs there at normal phone size.
