Apple says more than 100,000 apps built for the iPhone Duo are now live on the App Store. That milestone comes two weeks after the foldable went on sale on October 23. MacRumors confirmed with Apple that the figure counts apps built with the iOS 27.1 SDK or later.
Those are the apps that fill both of the Duo’s displays properly. For anyone switching from Android, though, the more useful question is which everyday apps still aren’t there. Several of Google’s own apps are on that list.
Susan Prescott, Apple’s Vice President of Worldwide Developer Relations, gave the figure in a statement reported by MacRumors and The Verge:
“Today there are well over 100,000 apps built for iPhone Duo already live on the App Store, and thousands of optimized apps are being added to the store each day.”
Google’s Apps Are Among the iPhone Duo Holdouts
As of MacRumors’ check, Google Docs, Google Sheets and Google Slides weren’t optimized for the iPhone Duo. Google Home and YouTube Music were missing too. If your work and home life run through Google Workspace, that’s a real gap on a phone built around a bigger screen.
Microsoft’s picture is mixed. Apple cited Excel, Word, PowerPoint and OneNote as recently optimized, per MacRumors. Yet Microsoft Teams and Microsoft Authenticator were still on MacRumors’ not-optimized list. Payment apps Venmo and PayPal were also absent, along with Duolingo, Starbucks and Bluesky.
Developers can push updates at any time, so some of these may change quickly. On the device itself, the Made for iPhone Duo badge in App Store listings shows which apps are ready.
What Apple’s 100,000 Figure Actually Counts
The count is based on which SDK an app was built with. Apps on the iOS 27.1 SDK get full optimization. Apps on the iOS 27 SDK fill most of the inner screen but avoid the status bar. Anything on the iOS 26 SDK or earlier runs centered, with black space on both sides.
That context matters. MacRumors notes the App Store carries millions of apps, so 100,000 is a small slice. And an app rebuilt on a newer SDK isn’t necessarily one a developer has redesigned around a two-screen layout. Other recent examples Apple cited include Zoom, Goodnotes, Halide Mark III, Etsy, NBA and NHL.
Other iPhone Duo Updates
- Apple Pencil: iOS 27.2 added Apple Pencil (USB-C) support on the iPhone Duo, per MacRumors
- Developer outreach: Apple says it has run more than 50 in-person workshops in 19 cities
If you bought a Duo and the app gaps are a dealbreaker, note that the standard return window for launch-day buyers closed on November 6.
