iPhone Duo apps & games
Apple's first foldable iPhone — a 5.4″ outer display that opens into a 7.6″ inner display. Here's everything that's been adapted for it so far.
iPhone Duo is a book-style foldable: closed, it is a compact 5.4″ iPhone; open, it becomes a 7.6″ landscape canvas with a near-invisible crease. iOS 27 adds Split View for two apps side by side, moves toolbar controls to the side of the display, and nudges interactive elements away from the fold when the device is partly closed.

When does iPhone Duo come out?
Pre-orders open Friday, October 16, 2026 at 5 a.m. PT, and iPhone Duo is available from Friday, October 23, 2026 in the US and more than 70 other countries and regions.
Which apps are optimized for iPhone Duo?
Apple named Netflix, Zoom, Slack and Detail as apps already adapted for iPhone Duo. FoldHunt tracks those launch partners plus every app and game whose developer has adapted it in the iPhone Duo Simulator.
How big are the iPhone Duo screens?
The outer display is 5.4 inches (1398 × 2034 pixels, 460 ppi) and the inner folding display is 7.6 inches (1878 × 2670 pixels, 430 ppi). Both share the same aspect ratio, so content scales proportionally when you open the device.
How do developers test apps for iPhone Duo before launch?
Build with the iOS 27.1 SDK in Xcode 27.1 and run the iPhone Duo simulator in Device Hub, which can open, close, rotate and fold the device. See our simulator guide for a full checklist.
