Overview
- Apple started selling the iPhone Duo on Friday, October 23, 2026, with a Japanese starting price of ¥364,800.
- The phone opens to a 7.6-inch display that Apple says gives roughly 1.5 times the screen area of the iPhone 18 Pro Max and measures about 12 cm by 16 cm when unfolded.
- The Duo supports split-screen operation for two apps at once and a half-open, propped position that lets users take hands-free calls.
- Launch-day scenes at the Apple Store in Ginza showed early adopter interest with customers queuing before opening and buyers citing video, gaming and multitasking as appeals.
- Analysts and reporters note Apple’s entry could revive a sluggish foldable market by offering mainstream app and software support for the larger form factor, which will be important to watch as real-world app behavior is tested.
