iPhone Duo launch: which apps are ready?

Pre-orders are open. iPhone Duo is in stores tomorrow, on October 23. Apps only use the whole inner display once they're rebuilt with the iOS 27.1 SDK. Apps built with the iOS 27 SDK fill most of it, and older ones open letterboxed, in a smaller window. This page tracks which apps are ready, from three sources kept strictly apart: what Apple says, what developers write in their release notes, and what owners report.

The most popular apps

201 of the 270 top apps on the US App Store have shipped an update since Apple began accepting iPhone Duo builds. 69 (26%) haven't, so they aren't built for the full Duo display yet.

Top Free, Top Paid and Top Grossing charts, as of October 22, 2026, excluding Apple's own apps. 9 mention iPhone Duo in their release notes. An update doesn't guarantee Duo support; owner reports confirm it.
