Apple’s iPhone Duo is set to debut with a 7.6-inch folding display and starts at a price point of $1,999.

It is Apple's first foldable smartphone, following the release of the iPhone 18 Pro lineup. The Duo runs on the A20 Pro chip, introducing an iOS experience optimized for the foldable hardware.

Preorders begin on October 16 and the phone becomes available in stores on October 23.

Unlike previous iPhones, the Duo uses Touch ID for biometric authentication. Apple has also incorporated Apple Pencil (USB-C) support, making the Duo the first iPhone with such functionality. The foldable design enables features like Split View, allowing two apps to run side by side, and supports up to 2TB of storage. The device has a 48MP Dual Fusion camera system supporting 0.5x, 1x, and 2x shooting, and up to 2x optical-quality zoom.
