A free, open source designer for App Store and Play Store screenshots, feature graphics and app preview videos. It runs in your browser/desktop: no account, no upload, no watermark, no paid tier, no server at all. Pick a template, drop in your app screens, and export every size both stores accept, including MP4 app previews conformed to exactly what App Store Connect wants. An optional AI agent builds the whole listing from your raw screenshots. Desktop apps for Windows, macOS and Linux.
Most screenshot tools want a subscription or an account. Artboard Studio is free and open source, and runs entirely in your browser. Lay out artboards, drop in device mockups (iPhone, Android, tablet, desktop, or your own frames), place your screenshots, add text and shapes, then export PNGs at the exact sizes Google Play and the App Store require. Projects save to your browser's IndexedDB, so nothing leaves your machine and there's no sign-up.
