Apple's first folding iPhone, the Duo, has a 7.6-inch unfolding screen, and within a week several major apps including Instagram, Threads, Slack and Google updated to properly support its larger display and vertical layout. Full compatibility requires developers to target the iOS 27.1 SDK. The device launches seven years after Samsung's original Galaxy Fold, with an IP68 rating and a largely concealed crease thanks to its display design and matte nanotexture screen.

Apple's upcoming iPhone Duo will require developers to recompile apps for iOS 27.0 just to fill the device's larger inner screen, with iOS 27.1 needed to access the Duo's new tab bar and other custom UI elements. Apple chose not to let iPad apps with resizable layouts run on the Duo, opting instead for a purpose-built interface exclusive to the new hardware.

Apple is preparing to give developers new tools to optimize their apps for the upcoming iPhone Duo, which is expected to ship next month alongside iOS 27. Until then, most third-party apps will only reach partial compatibility with the device's larger foldable display, while apps using custom toolbar designs will need extra work to fully adapt.
