Apple’s new iPhone Duo turns the interface on its head

Apple's introduction of the iPhone Duo marks a significant shift in brand strategy by embracing foldable technology and a vertical user interface, which challenges traditional design principles. This innovation not only enhances user experience by maximizing screen space but also reinforces Apple's commitment to intuitive design, ensuring that long-time users feel comfortable with the changes.

FastCompany: Not only is Apple going foldable with its new iPhone Duo , its user interface is going vertical too. The iOS 27 operating system for the iPhone Duo takes advantage of the foldable smartphone’s new form factor with user interface changes designed for the phone’s larger display. That meant turning parts of the iPhone’s longtime UI on its head.

The change not only maximizes screen space, but it puts major controls closer to the user’s thumb, helpful for a phone that folds out longer than it is tall. The controls stay in the same location whether the phone is open or closed. Apple said Wednesday at the iPhone Duo’s unveiling that it had to adjust every app’s layout and reconsider long-standing iPhone design principles because of the new vertical UI.

[Image: Apple] The larger screen also allows for showing two different home screens at once when it’s unfolded, or even two different apps. For an app like Email, full-screen mode shows both the inbox and messages at the same time. The iPhone Duo is also the first iPhone to support the Apple Pencil.

Despite the changes, Apple said it designed the new system to feel natural and familiar. The UI for the phone might be on a different axis, but it’s meant to be intuitive for longtime iPhone users.
