# How to Generate App Store Backgrounds with Claude

Claude streamlines App Store background creation as a multi-step terminal workflow. Generate backgrounds, upscale to exact device resolutions, and create a cohesive visual series through iterative conversation. Claude maintains a color story across your entire screenshot set because the full series is designed in one continuous session.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Describe the background: "Generate a clean gradient background for a fitness app with subtle geometric patterns"
3. Claude creates the background image using text_to_image
4. Upscale for retina: "Upscale this to 2x resolution for App Store requirements"
5. Generate a set: "Create 5 unique backgrounds for each screenshot in the series"

## Example Prompt

```
Generate 5 unique App Store screenshot backgrounds for a meditation app. Calming, soft gradients with nature-inspired abstract elements. 1290x2796 resolution for iPhone 15 Pro Max.
```

## Tips

- Use upscale_image to hit the exact pixel requirements for each device
- Ask Claude to maintain a color story that progresses across the screenshot set
- Generate backgrounds for both iOS and Android aspect ratios in one session
