How to Use Split View and App Pairs on iPhone Duo
The iPhone Duo's inner screen supports Split View in landscape, letting two apps run side by side. Users can create an app pair by tapping the divider, so the two apps launch together later, and can unpair by dragging the divider to an edge. The split is fixed at 50/50, unlike iPad multitasking.
The iPhone Duo is described as the first iPhone capable of displaying two apps simultaneously. On its 7.6-inch inner screen in landscape, users can place apps side by side, including two windows from supported apps such as Safari, Mail, Notes, and Files.
A saved app pair is created by tapping the divider between two open apps; afterward, opening either app also opens its partner. Dragging that divider fully to one side separates them. The split remains fixed at 50/50, and audio is limited to one app at a time.
This could affect iPhone Duo owners who multitask on mobile, especially people juggling messaging, maps, notes, or webpages. A fixed 50/50 split and single-app audio may shape how useful side-by-side work feels, while app pairs may reduce repeated setup. Developers and accessory makers may also need to consider landscape use and larger inner-screen workflows. Overall, it may make phone multitasking more routine without matching tablet flexibility.
