## What it does

The skill covers three jobs: auditing the icon you have, applying design rules, and setting up a test. The audit scores five areas out of 10 each — clarity at 60×60px, contrast in light and dark mode, differentiation from competitors, simplicity, and brand alignment. Fifty points total.

Design guidance is blunt. Two elements maximum. No text. The silhouette has to read at a glance. A category table walks through common visual patterns, from productivity to meditation, and points at where to break from them. There is also a designer brief template: three concepts at 1024×1024px, each mocked up inside a search results context before you commit.

For testing, it maps out Product Page Optimization in App Store Connect and Store listing experiments in Play Console. Change one variable per test — background color, mark style, dark versus light. The skill suggests at least 1,000 impressions per variant and a significance threshold of p < 0.05. With low traffic that takes a while, so fixing obvious icon problems by hand first is the cheaper move.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill app-icon-optimization -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/app-icon-optimization/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/app-icon-optimization/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill app-icon-optimization -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/app-icon-optimization/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill app-icon-optimization -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/app-icon-optimization/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install appeeky/aso-skills app-icon-optimization
```

2. **Manually: put the files in place**
- File: `.github/skills/app-icon-optimization/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill app-icon-optimization -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/appeeky/aso-skills --path skills/app-icon-optimization
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/app-icon-optimization/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill app-icon-optimization -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/appeeky/aso-skills/tree/HEAD/skills/app-icon-optimization/SKILL.md

## When to use it
- score a current icon against five criteria and get a total out of 50
- pick a background color that holds up in both light and dark mode
- stand apart from the top competitor icons in your category
- run an icon A/B test in App Store Connect or Play Console
- write a designer brief for three concepts tested at 60×60px

## Example prompts
- Audit my app icon against the app-icon-optimization checklist and tell me what to fix first
- Help me set up Product Page Optimization to test three background colors for the icon
- Write a designer brief for a meditation app icon — competitors are purple and blue

# App Icon Optimization

You help design, audit, and A/B test app icons to maximize tap-through rate (TTR) — the percentage of users who tap your app after seeing it in search results or browse.

## Why the Icon Is Your Most Impactful Asset

The icon is the **first thing users see** in search results — before the title, rating, or screenshots. A compelling icon can lift TTR by 20–40% with no other changes. In browse/charts, it's often the only visual element competing for attention.

## Icon Design Principles

### 1. Simplicity at Small Size

Icons render at 60×60pt (iPhone search results). At that size, detail disappears.

- Maximum 2 elements
- No text (illegible at small sizes; Apple discourages it)
- Strong silhouette recognizable at a glance
- Test at 60×60px before finalizing

### 2. Color Contrast Against the App Store Background

The App Store has a white/light background (light mode) and dark background (dark mode).

- High contrast on both modes
- Avoid white icons — they disappear in light mode
- Avoid very dark icons — they disappear in dark mode
- Consider adding a subtle shadow or border on your icon background

### 3. Category Visual Language

Match and differentiate from your category norms:

| Category | Common patterns | How to stand out |
|----------|----------------|-----------------|
| Productivity | Blue, clean, minimal | Warmer colors, bolder marks |
| Health/Fitness | Green, orange, energetic | Premium dark, sophisticated |
| Finance | Blue, green, conservative | Bold, distinctive mark |
| Games | Bright, characters, action | Premium/dark if competitors are loud |
| Social | Round shapes, soft colors | Sharp, distinctive if feed is soft |
| Meditation | Purple, blue, calm | Unexpected contrast color |
| Photo/Video | Gradient, camera | Single strong mark |

**Rule:** Look at your top 20 competitors' icons. Then design to be immediately distinguishable.

### 4. Recognizable Mark
