Speedtest by Ookla- Check your iPhone Duo screenshotsLow
iPhone Duo is on sale now, and Apple added a screenshot size for it. From April 2027, Apple requires them for every app and game submitted, so your next update after that can't go out without them. The public App Store page doesn't show whether Speedtest by Ookla has them yet.
- → Run your app in the iPhone Duo simulator in Xcode, on both the outer display and the inner (unfolded) one, and fix any screen that stretches or leaves empty bars.
- → Take screenshots at 1398 × 2034 pixels for the outer display and 2007 × 2853 pixels for the inner one (landscape works too: 2034 × 1398 and 2853 × 2007).
- → In App Store Connect, open your next version, choose iPhone Duo under Previews and Screenshots, upload them, and submit the version. They go live with it.
- → Already added them? Then you're set.
