A Picsew alternative
built for the App Store, not the timeline.

Picsew is great at the thing it's good at — stitching long screenshots on iPhone. For producing actual App Store screenshots at full resolution, in multiple device sizes, across multiple locales, Mockly is built for the workflow: real 3D device meshes in Metal, AI translation, and direct upload to App Store Connect.

About Mockly

Questions

FAQ

What is the best Mac alternative to Picsew for App Store screenshots?
Mockly is a native Mac alternative to Picsew built specifically for App Store screenshots. It renders real 3D device models in Metal at any output resolution, supports AI translation across locales, and uploads directly to App Store Connect — a workflow that's awkward to do from a phone-side stitching app.
Does Mockly render real 3D device models?
Yes. Mockly uses Apple's Metal framework to render real 3D device meshes — iPhone, iPad, and Mac — at the angle, lighting, and resolution you set. The output is true device-shaped, not a flat overlay.
Can Mockly translate screenshot text for App Store localisations?
Yes. Built-in AI translation generates localised variants of your screenshot text so you can ship the same screenshot set across multiple App Store locales in one pass.
Is Mockly a subscription?
No. Mockly is a one-time Mac App Store purchase — no recurring fee.
