Apple is adding a new “Made for iPhone Duo” badge to the App Store, giving users an easy way to identify apps that have been optimized for the company’s first foldable iPhone.
The new badge will appear on App Store product pages for compatible apps, with Apple also launching dedicated editorial collections highlighting apps and games designed to take advantage of iPhone Duo’s larger inner display and folding form factor.
Apple says optimized apps will be marked with the “Made for iPhone Duo” badge across the storefront beginning Friday, October 23, the same day iPhone Duo reaches customers.
The badge gives developers a visible way to show that their apps have been adapted for iPhone Duo rather than simply running in a compatibility layout. Apple previously opened App Store submissions for iPhone Duo-optimized apps, allowing developers to submit dedicated screenshots and assets for the new device.
Apple says developers have moved quickly to support the new form factor. Netflix, Prime Video, Paramount+, Slack, Zoom, Salesforce, Fantastical, Instagram and a growing number of other apps are being adapted to use the larger inner display, the device’s different folding positions and new multitasking capabilities.
The larger display also enables Split View multitasking on iPhone for the first time, allowing two apps to run side by side. Apple says Word and Outlook will also gain more desktop-like layouts on iPhone Duo in the coming weeks.
Developers can test their software using Xcode 27.1 and Device Hub, which can simulate iPhone Duo opening, closing, rotating and folding through its different supported positions. Apple says more than 2,000 developers have already attended over 50 iPhone Duo workshops in 19 cities worldwide.
The new badge should make it much clearer for buyers to see which apps are genuinely optimized for the foldable display as more developers release updates after launch. Apple also says additional iPhone Duo app updates will continue rolling out throughout the year.
iPhone Duo launches October 23, starting at $1,999 in the United States and £1,999 in the UK.
