A free iPhone mockup puts your app screen in an iPhone frame with a background and a short headline. This page also covers a mockup iPhone the other way around: same frames, same export. The file comes out at 1320×2868 (6.9") or 1242×2688 (6.5"), which are sizes App Store Connect accepts. No signup and no watermark.
Drop in a raw capture, pick an iPhone frame or go frameless, and write one headline per screen. The set stays aligned so the first screenshot and the last one look like one listing.
The iPhone mockup is rendered in your browser. The image is not uploaded. You download a zip and upload it yourself in App Store Connect.
Apple asks for a 6.9" screenshot set for iPhone apps. This tool exports 1320×2868, one of the portrait sizes Apple accepts for that display. If you are not supplying 6.9" screenshots, the 6.5" class is the fallback, and this tool exports 1242×2688 for it.
Apple also accepts 1290×2796 and 1260×2736 for 6.9", and 1284×2778 for 6.5". Those sizes are not exported here. The full table, including iPad, is at https://freeappscreenshots.com/app-store-screenshot-sizes.
