iPhone Duo screenshots required from April 2027
App Store Connect accepts iPhone Duo screenshots now, and they become required for App Store submissions in April 2027.
The details
- Sizes: 1398 × 2034 for the outer display and 2007 × 2853 for the inner display, in portrait (landscape swaps them).
- Apple's screenshot specification ties the requirement to apps built with the iOS 27.1 SDK or later. The App Store Connect release notes of 5 and 15 October 2026 say any app or game submitted from April 2027 will need them.
- Apps that provide iPhone Duo screenshots get a badge on the product page saying the app is optimized for iPhone Duo.
What to do
- Keep screenshot source files editable so you can produce Duo frames.
- Test your app's layout on both Duo displays before capturing.
- Plan the screenshots into a release before April 2027.
