You don’t need Photoshop or Figma to ship App Store and Google Play screenshots. Here’s the step-by-step workflow with AppScreenStudio.

Step 1: capture the raw screens

On iOS, use the Simulator (Xcode → Window → Devices and Simulators → ⌘ S). On Android, use Android Studio's Device Manager or run adb exec-out screencap -p > screen.png.

Step 2: pick a template

Browse the template library and pick one that matches your app's category. Don’t over-think it — the template is a starting point, not a constraint.

Step 3: drop in your captures

Drag-and-drop your raw captures into the editor. Each device slot accepts an image; the editor smart-fits them inside the device frame.

Step 4: edit headlines and colors

Replace the placeholder headline with one short, benefit-led line per screenshot. Pick a brand color from the palette or paste a hex.

Step 5: export

Hit the export button. AppScreenStudio outputs every required iPhone and iPad size (or Android phone / tablet) at the exact dimensions Apple and Google expect.

Step 6: upload

Drag the exported PNGs straight into App Store Connect or Play Console. They’ll pass validation on the first try.
