Apple adds ‘Made for iPhone Duo’ label to the App Store
Key points
- Apple will label apps that are optimized for the iPhone Duo with a "Made for iPhone Duo" badge in the App Store.
- To earn the label, developers must build their app with the iOS 27.1 SDK or later.
- Optimized apps fill the entire inner display, with the toolbar placed vertically below the status bar.
- Apps built with the iOS 27 SDK fill most of the inner display but still avoid the status bar on the right edge.
- Apps built with the iOS 26 SDK or earlier run on the iPhone Duo but sit in the center of the inner display with empty space on each side.
Summary
(AI)
This is an official Apple announcement, made in a press release that highlights apps optimized for the iPhone Duo. It is not a rumor or a leak.
The label follows from how the foldable’s inner display treats apps built at different times. Apps update to the new layout as developers rebuild them with a newer SDK, so the badge marks a gradual process rather than a single switch. MacRumors reports that more apps are being optimized every day and points owners to the App Store’s updates menu to catch them. The coverage does not say how many apps carry the label yet.
