Iphoneduo
In short
The iPhone Duo is Apple's first foldable smartphone, released on 23 October 2026. It was announced at an Apple Park event on 9 September 2026 alongside the iPhone 18 series.
In plain words
It is a mobile phone with a screen that can fold in half. This allows the device to be compact when closed but provides a larger display when opened.
A simple example
You can fold the phone to fit it into a small pocket, then unfold it to watch a film on a much larger screen.
Why it matters
This marks Apple's official entry into the foldable phone market. It changes how users interact with mobile multitasking and screen space.
Easy to mix up
Do not confuse it with the iPhone 18 Pro, which uses a traditional rigid screen design.
