The four iPhone Duo sizes
App Store Connect accepts 2007 × 2853 and 2853 × 2007 for the inner display, and 1398 × 2034 and 2034 × 1398 for the outer display. All four are in Screen Studio Kit's Canvas list, under iPhone, and they count as one App Store requirement.
Dedicated iPhone Duo screenshots are optional for now. From April 2027 they are required for apps built with the iOS 27.1 SDK or later, so Preflight shows a note about them until then, with an Add iPhone Duo inner button.
- Inner portrait: 2007 × 2853.
- Outer portrait: 1398 × 2034.
- Landscape uses the same dimensions reversed.

Use captures made for the Duo
Each page shows the same capture at every size in the project, and the Duo's inner display is much wider than an iPhone screen. Your iPhone screenshots would be cropped, so make the Duo set in its own project with captures taken on the Duo or at its size.
Click Add Screens, then Import screenshot files, and choose your captures: the first goes into the frame, and each further capture gets a new page with the same layout. Type each page's headline in the Inspector.

Fold the phone on each page
Select the phone to choose a finish, Night Sky or Star White, and how far it is open: Flat, Open book, Half open, or Closed, or drag the Hinge slider to any angle from 0° to 180°. Each page keeps its own hinge angle, so the phone can open a little more on every page of the set.
Apply appearance copies the finish, shadow, and rotation to every page and keeps each page's hinge angle.

Show your app on the outer display
A closed phone shows its outer display. Click Import outer image under Fold to show your app there; with no image, the outer display stays off and Preflight warns about it. On a portrait canvas the closed phone lies sideways, so use a landscape outer capture, 2034 × 1398.
Every language can have its own outer display image. After you add a language, the Fold section offers Import outer image for that language; until you do, the default image is used.

Export the inner and outer sizes
Add iPhone Duo outer from the Canvas list to export the same pages at 1398 × 2034. At that size the automatic frame is the folded phone, showing each page's own capture.
Open Export, untick the sizes you don't need, choose a folder, and click Export images. The PNG files have the size in their names, such as 01-screenshot-1-en-phone-2007x2853.png.

Made on your computer
Screen Studio Kit makes the screenshots on your computer. Your captures are not uploaded unless you publish to a store yourself, and no AI is involved.
