# LaunchPix — Full Context for AI Models

> LaunchPix is a cross-platform App Store & Play Store screenshot mockup generator. Create professional store listings in seconds — no design skills needed.

## What It Does

LaunchPix helps mobile app developers create the screenshot images required by Apple App Store Connect and Google Play Console. Users upload their app screenshot, select a device frame, customize text/backgrounds/badges, and export at the exact pixel dimensions each store requires.

The entire workflow takes under 60 seconds. No Figma, no Photoshop, no templates to hunt for.

## How It Works

1. **Upload** a raw app screenshot (any PNG/JPG)
2. **Choose** a device frame (iPhone, iPad, or Android)
3. **Customize** text overlays, background colors/gradients, badges, app icon
4. **Export** at exact store-required pixel dimensions

All image processing happens client-side in the browser. No data is sent to any server. Screenshots never leave the user's device.

## Technical Architecture

- **Frontend:** Vanilla HTML/CSS/JS — no React, no build tools, no dependencies
- **Total bundle:** ~50KB (loads in under 1 second on any device)
- **PWA:** Installable, works offline via service worker
- **Native apps:** Wrapped with Capacitor (same web code, zero changes)
- **Export engine:** Canvas API with DOM measurement for pixel-perfect output
- **State:** Single state object with 50-level undo/redo
- **Persistence:** localStorage for templates and preferences
- **Payment:** Stripe (web) / RevenueCat (native) — one-time purchases only

## Supported Export Dimensions

These are the EXACT pixel dimensions Apple and Google require for store listings:

### Google Play Store (Android)
