About Screenshot Lab

Why we built this

Every indie developer knows the pain: you've spent months building a great app, and now you need App Store screenshots. So you open Figma, start searching for templates, manually type captions you hope will work, and spend hours aligning device frames pixel by pixel. For each new version. For each localization. Multiply that by the number of apps you maintain.

We built Screenshot Lab because developers shouldn't need to be designers to have great screenshots. And more importantly, screenshots shouldn't be based on guessing — they should be based on data about what actually works in your app's category.

What Screenshot Lab does

Screenshot Lab is a native macOS app that brings AI intelligence to App Store screenshot creation. Instead of starting from a blank canvas, it researches your competitors, analyzes their screenshot strategies using computer vision, and generates ASO-optimized captions tailored to your app and market.

The app uses Apple's Vision framework for OCR analysis of competitor screenshots and Google's Gemini AI (via Firebase AI Logic) for caption generation and localization. Everything runs in a native SwiftUI interface built for macOS 14+.

What it's not (yet)

We believe in being transparent about where we are:

  • Mac-only — No Windows, Linux, or web version. We're focused on doing one platform really well.
  • 5 templates — Compared to 20-30+ from some competitors. We're adding more, but quality over quantity.
  • iOS/App Store only — No Google Play or Android support currently.
  • New product — Launched in February 2026. Some competitors have years of polish.

We acknowledge these limitations because we think honesty builds better products and better relationships with users.

The technology

Screenshot Lab is built with SwiftUI and SwiftData. AI features use Google Gemini through Firebase AI Logic, with Firebase App Check for security and Firebase Authentication for session management. Screenshot analysis uses Apple's Vision framework for on-device OCR. All project data is stored locally on your Mac.
