The short version
- Split View lets you use two apps side by side on iPhone Duo.
- StandBy works on either display without charging.
- The 7.6-inch inner display provides room for multitasking when the phone is open.
iOS adapts content as you fold, turn, or flip the phone.
What iPhone Duo does in each pose (pick a pose)
Pose picker: choose Landscape, Portrait, Seated, Standing or Closed to see what iPhone Duo does in each pose, from Split View app pairs to StandBy without charging.
The inner and outer displays share a consistent aspect ratio, so more of your content fills the screen whether the phone is open or closed.
Landscape: Pair apps with Split View
With iPhone Duo open in Landscape, move an app to one side of the inner display, then launch a second app on the other. Split View brings side-by-side use of two apps to iPhone for the first time.
You can also open two windows of the same app, such as Safari for comparison shopping. You can quickly swap between apps and save pairs of apps to come back to later.
Portrait: Type and keep a video above another app
Portrait gives you a wider keyboard for comfortable typing.
You can pin a video to the top and keep watching while using another app.
Seated: Set the viewing angle with controls below
Set iPhone Duo down in Seated to watch a show or follow a workout.
The controls sit on the bottom, keeping them within easy reach while you watch.
Standing: Use StandBy without a charger
Set iPhone Duo down and it enters StandBy on the outer or inner display. StandBy can turn the phone into a bedside clock, a photo frame, or a hub for widgets.

The new Calendar and Weather faces join Clock and Modular. The Photos face supports Shared Albums. Every face offers deeper customization, with new colors, fonts, and complications.
Closed: Reach side controls on the outer display
The 5.4-inch outer display supports one-handed use. Essential controls move to the side for easier reach, leaving more vertical space for apps.
