You can now display up to 10 screenshots on your product page on the App Store for iPhone, iPad, Apple Watch, and Apple TV, to show customers more of your app’s experience.
The increase will be helpful for applications with extensive functionality that can't be shown off in just five screens.
Use images captured from your app’s UI to visually communicate your app’s user experience. You can feature up to ten screenshots on your product page. Depending on the orientation of your screenshots, the first one to three images will appear in search results when no app preview is available, so make sure these highlight the essence of your app. Focus each subsequent screenshot on a main benefit or feature so that you fully convey your app’s value.
