Those who pre-ordered the iPhone Duo should begin receiving their devices today. As Apple’s first ever foldable, the smartphone is capable of offering the same user experience regardless of whether it’s in its folded or unfolded state. That is, provided the app has been optimised for the new form factor. With this in mind, the tech giant is introducing a label for identifying apps that are compatible with the handset.

This label comes in the form of a “Made for iPhone Duo” badge, which is displayed on the app’s page on the App Store. Essentially, the badge lets users know whether the software will play nice with the phone’s unusual proportions. Supported apps should adapt to the different layouts, transitioning seamlessly from one screen to the other.
