Zoom and These Microsoft Apps Now Optimized for iPhone Duo

Over the weekend, the video calling app Zoom was updated with iPhone Duo optimization. On the device's large inner display, users can now see shared content such as the host's desktop and other participants on a call at the same time.

In addition, four Microsoft apps were updated with iPhone Duo optimization today: Word, PowerPoint, Excel, and OneNote. Microsoft Outlook was already optimized for the device since it launched, but Microsoft Teams has yet to be.

Apps built with the iOS 27.1 SDK or later are fully optimized for iPhone Duo. These apps extend to fill the entire outer and inner displays on the device, with toolbars and tab bars appearing vertically below the status bar.

Apps built with the iOS 26 SDK or earlier run on iPhone Duo, but they appear in the center of the inner display, leaving lots of empty space.

In the App Store, optimized apps have a "Made for iPhone Duo" label on the device.
