ButterKit

Native macOS studio to create, translate and publish App Store screenshots

Capture straight from Xcode

One click grabs a screenshot from the Xcode Simulator Device Hub and imports it as a new artboard, so you can iterate on designs as fast as you can build.

Fastlane and folder sync

Link a folder of images — for example a Fastlane or UI-test output directory — and your artboards update automatically whenever new localizations land.

Real 3D device frames on Metal

Place screenshots inside high-resolution 3D devices, rotate them to any angle and pan across artboards for panoramic backgrounds, all rendered smoothly up to 120fps.

Translation for App Store languages

Localize screenshots and app metadata into the full set of App Store Connect languages from one artboard, with designs staying in sync across languages.
