Feature graphic
A 1024 × 500 banner image required by Google Play — not the App Store, which has no equivalent.
A feature graphic is a 1024 × 500 pixel banner that Google Play requires on every listing. It appears at the top of your Play Store page, is used when Google features an app editorially, and serves as the backdrop when a promo video is present.
People search for it alongside App Store terms constantly, so the useful thing to say is the plain one: the App Store has no feature graphic. There is no banner slot on an iOS listing. The closest equivalents are the app icon, which carries far more weight on iOS than most teams give it, and the first screenshot, which is what actually gets seen in search results.
If you ship on both stores, the mistake is treating the Play feature graphic as a resized iOS screenshot. It is a different job: a wide banner read at a glance, usually the app name plus one line, not a phone frame. Text near the edges gets cropped on some surfaces, so keep the important part centred.
Both stores agree on one thing here — no device frames containing store badges, no "Download now" calls to action, and no screenshots of the store inside the artwork.
