iPhone Duo arrives October 23

Does it work on Duo?

See how every app looks on iPhone Duo’s inner display — full screen, partly adapted, or stuck with black bars.

Open it up

Every app runs. Not every app fits.

On the 5.4″ outer display, apps work like on any iPhone. Open iPhone Duo and the 7.6″ inner display shows each app one of three ways, depending on how recently it was rebuilt.

Black bars

Built with iOS 26 or earlier. Runs in a phone-sized window.

Partly adapted

Built with iOS 27. Fills more, with some space left over.

Full screen

Built with iOS 27.1. Edge to edge, often with new layouts.

Read the Readiness Report

Before launch, most apps are “not confirmed” — nobody outside Apple has an iPhone Duo yet. We only mark an app once there’s public evidence.

The apps everyone’s asking about.

Big names you’ll open on day one. We’ll update each one as soon as there’s evidence — or as soon as you tell us.
