Anyone shipping an iPhone or iPad app can use AppScreen in a browser tab to put together the screenshots for its App Store page. Rather than editing slides one by one, you work on a single wide strip: place your captures, set them inside device frames, add captions, and let a phone or a sentence cross over between neighbouring slides. When the layout is done, the strip is cut into separate images ready for upload. Presets give you a place to begin. The editor is free to try. Paying $9 once unlocks Pro, which brings iPad frames, pattern exports, files kept on your own disk, no cap on projects, plus an agent/MCP hookup. Built by Stewan Silva (@stewones).
