Questions

Which apps work on iPhone Duo?

Every iPhone app runs on iPhone Duo. On the 7.6-inch inner display, 111 of the apps we track are confirmed to fill the screen; apps built with the iOS 26 SDK or earlier show black bars until they’re updated.

How can I tell if an app is made for iPhone Duo?

Apple shows a “Made for iPhone Duo” badge on App Store product pages for optimized apps. This list also uses developers’ release notes, the iPhone Duo screenshots on App Store listings, and the SDK each app is built with.

Why do some apps still have black bars?

Apps built with the iOS 26 SDK or earlier run in a phone-sized window on the inner display. The bars go away once the developer releases an update built with the iOS 27.1 SDK.
