If your app is the same across multiple device sizes and localizations, simply provide the highest resolution screenshots required. For iPhone, screenshots for 5.5-inch devices (iPhone 6s Plus, iPhone 7 Plus, iPhone 8 Plus) are required. For iPad, screenshots for 12.9-inch iPad Pro (2nd generation) are required.
Screenshots for iPhone XS Max are optional. These screenshots will scale down for iPhone XR, iPhone XS, and iPhone X, and will display with rounded corners.
Screenshots for 12.9-inch iPad Pro (3rd generation) are optional. These screenshots will scale down for 11-inch iPad Pro, but not for older iPad devices, and will display with rounded corners.
App previews will scale down in the same way.
For details on how to upload screenshots, see Upload app previews and screenshots in App Store Connect Help.
Go to your app’s version page on App Store Connect, and click on Media Manager. If you’ve previously added 5.5-Inch Display screenshots, uncheck “Use 5.5-Inch Display,” and drag in your customized screenshots for the appropriate device size. For additional details, see Add screenshots and previews for other device sizes and localizations in App Store Connect Help.
If you’ve already added your 5.5-Inch Display screenshots, you can toggle between localizations at the top right of your app’s version page. Choose the localization you’d like to update, uncheck 5.5-Inch Display screenshots used for your primary localization, and drag in your own custom screenshots for that locale. You can also do this from the Media Manager page. For additional details, see Add screenshots and previews for other device sizes and localizations in App Store Connect Help.
App previews are optional short videos that showcase what’s great about your app to help customers make an informed decision about downloading your app. Customers can watch app previews, which generally feature device-captured footage of your app, directly from your product page in the App Store. Each app can have three app previews for each supported device size and App Store language. To learn more, such as how to create an app preview, see Show More with App Previews. For technical specifications, see App Preview Specifications.
No, 6.5-inch display screenshots don’t cascade down to earlier device sizes due to differences in the aspect ratio and the variation in layout for apps optimized on iPhone X and later devices. For additional information, see Upload app previews and screenshots or Screenshot specifications.
