Zoom and several Microsoft Office apps have been updated to take advantage of the iPhone Duo's large inner display, MacRumors reports, a sign that third-party support for Apple's first foldable is starting to broaden.
According to MacRumors, Zoom received its update over the weekend. On the Duo's inner screen, the app can show shared content, such as a host's desktop, next to the other call participants instead of forcing everything into a single view. Microsoft updated Word, PowerPoint, Excel and OneNote on Monday, November 2. Outlook, the report notes, has been optimized since it first launched. Microsoft Teams has not yet received the same treatment.
What "optimized" means
MacRumors explains that apps built with the iOS 27.1 SDK or later are fully optimized for the Duo. They fill both the outer and inner displays, and their toolbars and tab bars sit vertically below the status bar. Apps built with the iOS 26 SDK or earlier still run on the device, but they appear in the middle of the inner display with a good deal of unused space around them.
Optimized apps also carry a "Made for iPhone Duo" label in the App Store, which gives buyers a quick way to see which of their apps make full use of the foldable screen.
Why it matters
The iPhone Duo went on sale on October 23 in more than 70 countries, and demand has outpaced supply: Apple CEO John Ternus said on the company's earnings call that shortages have no end date in sight, according to MacRumors. For people who do get a Duo, software support is a large part of the experience. A foldable with a bigger inner display is most useful for work-style apps, such as video calls with shared screens and document editing, and those are the categories Zoom and Microsoft have now addressed.
Apple's own product page presents the Duo's inner display as a central part of the device, but the platform's value will depend on developers rebuilding their apps for the new layout. Microsoft's Office apps and Zoom are among the most widely used productivity tools, so their updates may encourage other developers to follow.
The report does not say when Teams will be updated, and neither Microsoft nor Zoom has been quoted on future plans for the Duo in the material reviewed. Cupertino News will follow further developer updates as they appear.
