Apple Opens App Submissions for Foldable iPhone Duo, Launching October 23

Apple announced on Monday, October 5, 2026, that its first foldable iPhone, the iPhone Duo, will be available to customers starting October 23, 2026. Developers can now submit their optimized applications to the App Store. The company requires developers to rebuild their apps using Xcode 27.1, which supports the new device. Starting in April 2027, all new app submissions must include screenshots specifically for the iPhone Duo.

The iPhone Duo, unveiled on September 9, 2026, features a 7.6-inch internal screen and a 5.4-inch external screen for one-handed use when folded. Both screens offer a 120Hz refresh rate and a peak brightness of 3000 nits. The device is powered by the A20 Pro processor and has a dual-battery system, offering up to 31 hours of video playback on the internal screen and 44 hours on the external screen. Apple claims its wired fast charging can restore 50% battery in about 20 minutes, though these figures have not been independently tested.

The phone includes a dual rear camera system with a 48-megapixel main sensor and a 48-megapixel ultrawide sensor with 2x zoom. It also has a 12-megapixel front camera and an under-display camera for the internal screen. The chassis is made of titanium and has an IP68 water and dust resistance rating.

Apple highlighted that the large internal screen enables split-screen multitasking, such as browsing the web while using Siri. The full functionality of the device will be realized in updated applications, which is why Apple linked the submission deadline to the launch date. The company has not specified how un-updated apps will perform.

Pricing in the United States starts at $1999 for the 256GB model. In Israel, the 256GB model is expected to cost 8199 shekels, with higher prices for larger storage options. Pre-orders begin on October 16, with the device rolling out to 70 countries and regions on October 23 and an additional 28 regions on October 30.
