NewAppScreenStudio

AppScreenStudio is an online tool for taking screenshots of the App Store and Google Play Store. The most troublesome step for developers when launching an app is to package the original screenshots into promotional images with titles, phone frames and backgrounds, and export them in several sizes.

It provides 44 sets of ready-made templates. Each set is a complete set of store screenshots. The title, layout, device frame and background are all matched. Just drag your application screenshot into it and change the text. Most templates are free, and some advanced templates require Pro. Once done, export all the sizes required by the two stores with one click. What is relatively new is that it supports MCP, which allows AI agents such as Claude Code, Codex, Cursor, and Gemini CLI to directly help you design screenshots.

The official website shows that more than 9,300 developers have used it. It is free to start and no card is required. Suitable for independent developers and people doing app store optimization.
