App screenshots / preview video
The swipeable images and short muted video on your product page: captioned, device-framed shots that sell the app before anyone installs.

What it is
Screenshots are not screenshots. They are captioned posters built around a screen capture: a short benefit headline, a device frame or a full-bleed crop, and a background color that matches your brand. Apple calls the video an 'app preview' (up to three, 15 to 30 seconds, autoplaying muted); Play calls it a promo video and also wants a 1024x500 feature graphic.
Your first assets carry almost all the weight, because a browsing person forms an opinion before they ever open the product page. How many show up, and where, is not one fixed number: Apple can surface up to three assets in search depending on your orientation and how the listing is placed, and Play's search presentation varies by surface and device. Build as if only the first two get seen, so put the single clearest benefit on panel one, the second-best on panel two, and treat the rest as the reward for a swipe. Caption in outcomes ('Scan a receipt in two seconds'), never in UI labels ('Dashboard').
Gotchas: the preview autoplays with sound off, so it has to read silently, and Apple requires app previews to be captured from actual device screen recordings, not motion-graphics fakery. Upload the largest required iPhone size and Apple scales the rest; Play wants its own set. And whatever you do, keep captions clear of the notch, the status bar, and the home indicator.

Build 6 finished App Store screenshot posters for my app: [paste description]. Use these inputs only: my raw screen captures [attach files], my logo and brand assets [attach files], and my type family and hex colors [paste]. Do not invent, redraw, or embellish any UI that is not in the captures I gave you. For each panel give me the caption (6 words maximum, benefit not feature), which capture it frames, and the layout: caption above or below, device frame or full-bleed crop, background color, and one highlight element (arrow, badge, or zoomed detail). Panels 1 and 2 must stand alone, since they may be all anyone sees. Export the set at [exact pixel dimensions for my required iPhone display size], plus a separate iPad variant at [exact dimensions] and a Google Play set at [exact dimensions] with a 1024x500 feature graphic. Keep captions clear of the notch and home indicator. Then script a 20-second silent app preview using the same order of beats, cut only from real device screen recordings.
