Apple’s first foldable iPhone, the iPhone Duo, did not get off to the smoothest start when it came to app support. Shortly after its launch, users began noticing interface issues with some popular apps, raising questions about how well existing iPhone apps would adapt to its unusual wider display. However, Apple now says that over100,000 apps have been optimised for the foldable.

Apple iPhone Duo gets over 100,000 optimised apps

According to a report by The Verge, Apple says developers have been quick to adapt their apps for the iPhone Duo’s foldable display. The device runs iOS 27.1, and its wider screen when unfolded requires developers to make changes to how their apps look and function.

Susan Prescott, Apple’s vice president of Worldwide Developer Relations, said the company has been encouraged by the response from developers since the device’s launch.

“It’s been wonderful to see how quickly developers have embraced iPhone Duo, and we’re grateful for their creativity and innovation,” Prescott said in a statement.

She also noted that the number of optimised apps on the App Store continues to increase, with developers releasing updates at a faster pace as more users get their hands on the foldable.

Apple’s reported 100,000-app milestone is a promising start for a device that introduces a different screen format to the iPhone lineup. However, the number alone doesn’t tell us how well these apps actually perform on the larger display.

Why some apps still struggle on the iPhone Duo

Despite the growing number of optimised apps, early experiences suggest that developers still have some work to do. Instagram, for instance, received attention after users noticed interface issues on the iPhone Duo, even though the app carried Apple’s “Made for iPhone Duo” label.

Instagram chief Adam Mosseri also acknowledged the challenges of adapting the platform to the foldable’s design, describing the device as a “bit of a tricky form factor”.

This highlights an important difference between making an app compatible with a new screen and actually delivering a good user experience. An app may technically support the iPhone Duo, but that doesn’t guarantee that its interface, navigation and features will feel natural when the device is unfolded.

With more developers working on updates every day, the experience should continue to improve. For now, Apple’s growing collection of optimised apps is a good sign, but the real test will be how consistently these apps work when users start relying on the foldable as their everyday smartphone.
