AppScreen Studio, CoreData Studio, and PriceLocus streamline screenshots, data debugging, and pricing so releases ship faster.

If you’re an indie developer, marketing agency, or UI/UX designer, you know the struggle: you’ve finally finished building your app, but now Apple needs pixel-perfect marketing screenshots for every single device size. Add localization into the mix, and you’re suddenly staring down hours of manual resizing in tools like Figma or Photoshop.

AppScreen Studio — Design Once, Sync Everywhere

Enter AppScreen Studio. Built specifically for macOS, this native app is designed to completely streamline your app submission workflow, boost your ASO (App Store Optimization), and increase your click-through rates — all without requiring a design degree.

  • Design Once, Sync Everywhere: With the smart “Sync to All” feature, you simply design your master screenshots (for example, on the 6.9” display) and the app instantly scales and adapts them for 6.5”, 5.5”, iPads, and Macs.
  • One-Click Localization (45+ Languages): Auto-translate all text layers into over 45 languages with a single click and manage them all inside a single project.
  • Massive, Up-To-Date Device Library: Photorealistic devices, clean clay mockups, or minimal flat styles — with instant access to the newest Apple ecosystem hardware.
  • Lightning Fast & Native to macOS: Built with SwiftUI, with a rebuilt editing engine for buttery-smooth 4K editing, automatic local saving, and full offline support.
  • Pro-Level Polish, Zero Friction: “Magic Gradient” backgrounds, native macOS Emoji picker integration, and full Dark Mode support.

Best of all? It offers a generous free tier allowing up to 3 project screenshot generations per month!

CoreData Studio — inspect your app’s data layer

CoreData Studio is a native macOS viewer and editor for CoreData and SwiftData stores: open a store, inspect the schema, browse tables, and make safe, deliberate edits — plus an ER diagram visualizer for your data model.

PriceLocus — price for every market

PriceLocus optimizes your App Store pricing across 175 regions using Purchasing Power Parity (PPP), so a price that feels right in San Francisco also converts in São Paulo.

You shouldn’t have to spend a week creating marketing assets after spending months writing code. These tools handle the heavy lifting of App Store Connect requirements so you can focus on shipping.
