Apple has updated its Apple Support app to add support for the iPhone Duo and iOS 27.1, which the Duo ships with. The app now displays properly on the iPhone Duo's wider screen and can be used alongside other apps in Split View.
iPhone Duo reviews went live today, and poorly sized apps have emerged as a recurring complaint among reviewers. Apps that have not been updated for the iPhone Duo are letterboxed, showing thick black bars on each side of the screen.
Apple will continue adapting its apps for the device, and plenty of third-party iPhone Duo app updates are expected in the coming weeks. Any major change to screen size results in early hiccups, but a few months from now, app compatibility with the iPhone Duo should be largely fixed.
Apple Support is Apple's dedicated app for troubleshooting device issues and looking up support documents. It is a free download from the App Store.
