Problem solved by Screen Studio Kit
Put app captures in editable device frames
Add platform-aware phone, tablet, watch, and desktop frames to app-store screenshots without flattening the composition.
See it in the app
A focused workflow, on your computer.
Project editing and screenshot rendering happen locally. Store purchases and license checks use the platform store. A publishing dry run renders and checks the screenshots; with Direct API it also signs in to App Store Connect, Google Play, or Partner Center to check the app and its listings, and uploads nothing. Screenshots are uploaded only when you confirm.

The problem
Why the usual workflow gets in the way.
A baked-in phone mockup looks finished until the capture, frame, crop, or output size changes. Then the complete image has to be recreated.
The solution
How Screen Studio Kit handles it.
Screen Studio Kit treats device frames as editable scene layers alongside captures, text, images, shapes, and groups. Version 1.2 adds live Turn and Tilt controls, so perspective remains adjustable across outputs and is reproduced by native export.
Three short steps
From source to answer.
- 01
Import the source-resolution app capture.
- 02
Add the matching platform-aware frame.
- 03
Adjust and preview it across selected outputs.
