Uniframe is a native macOS app for designing App Store screenshots and device mockups. Place a real device in 2D or 3D, drop a screenshot into its screen, add captions, and export at the exact sizes each store requires. It runs entirely on your Mac.

Put the screenshot inside a real device.

Uniframe includes 47 device frames: 27 3D models and 20 2D bezels, covering iPhone, iPad, Mac, Apple Watch, Android phones and tablets, laptops, desktop displays and gaming handhelds. The screenshot stays pixel-accurate inside the glass.

  • Pose and light each 3D model separately.
  • Run one device across two artboards for a panorama.
  • Mix 2D and 3D devices in one project.

A real design canvas

Artboards, layers and properties in one window.

Lay out a full screenshot set side by side. Every device, image and caption is a layer you can select, adjust and reorder.

Start from a preset for the store you are designing for, or set a custom size.

Apple Intelligence

Backgrounds and captions without leaving the layout.

Generate backgrounds through Image Playground, and write or rewrite captions, while you work on the layout. Both run on your Mac.

These features need Apple Intelligence. The rest of Uniframe works without it.

Localization

One project, every language.

Add a language and the captions switch with it. Write the caption text for each locale, then export every language and every size together.

Export

Every size, in one pass.

Export the whole set at the dimensions each destination requires, correctly named. Store guidance warns you about problems and never blocks the export.

Formats: PNG, JPG, WebP, HEIC, TIFF, PDF, SVG and PSD. PSD and SVG files keep their layers and are never flattened.
