Description

ButterKit
ButterKit helps app developers reach more users faster. Quickly create stunning screenshots for the App Store; capture straight from Xcode Simulator, edit with 1-click templates and 3D devices, localize to all 39 App Store Connect languages, and upload/export. It’s fast and private with no accounts or ads. Apple M1 or newer is recommended for best performance (Intel works too).

KEY FEATURES
• App Store Screenshot Design Studio: pro typography, gradient tools, and precise 3D device controls (style, bezel, rotation, scale)
• Professional Templates: designer-built layouts make screenshots look polished in minutes
• Capture from Xcode Simulator: pull your app screenshots directly from Xcode Simulator into photorealistic 3D devices
• Automatic Translations: use built-in translations for 20+ languages, or bring your own OpenAI API key to translate to all 39 supported ASC languages (Pro feature)
• Automatic App Store Connect Uploading and Batch Image Exports
• Built for Real Workflows: infinite canvas, keyboard shortcuts, undo/redo, file saving, custom fonts, gradients, and style presets.
• Mac-native, Metal-accelerated: buttery-smooth editing with a realtime 3D renderer and lifelike iPhone, iPad, and Mac device frames.
• Private by Design: all core features run on-device. Optionally use your own API keys for additional translation options (Pro feature)

BUILT FOR DEVS & DESIGNERS
ButterKit streamlines the full pipeline from capture, edit, translate, and export - so you spend time refining your product, not wrangling artboards.

REALTIME 3D, ZERO WAIT
Rotate, frame, and light photorealistic devices in a GPU-powered viewport. What you see is what you ship: responsive, precise, and smooth.

LOCALIZE IN MINUTES
Translations automatically respect typographic rules and constraints, keeping captions readable and aligned across all localizations.

PRO FEATURES
• Available as a one-time purchase or subscription
• Remove "Made with ButterKit" watermark
• Publish metadata directly to App Store Connect
• Unlock OpenAI API usage for translations to all 39 App Store Connect languages

What's new

  • Version: 1.7.21
  • Updated:
  • • New: Delta Translation — ButterKit now tracks which text blocks changed and only re-translates those. More predictable results, lower token usage. No more re-translating your entire project because you fixed a typo.
    • New: Preview Navigation — Dedicated left/right buttons + keyboard arrow support in the Preview window. (thanks David M)
    • New: "Delete artboards?" confirmation modal to prevent accidental deletion. (thanks Discord crew)
    • New: Toast notifications after translation so you know when it's done.
    • Fix: Device Overflow alignment — Multi-panel exported images no longer misalign. (thanks u/habitoti)
    • Fix: Device Overflow + rounded corners now appears correctly in the editor.
    • Fix: Preview spacing now more closely matches the actual App Store layout.
    • Fix: issue where some projects would open with a non-interactive ghost artboard containing locked text. Projects affected by this condition will now initialize correctly.
    • Fix: you can now properly multi-select and make batch updates in the Localization Panel (e.g. to change Translation Provider for many languages).
