# App Description Writer

Generate compelling App Store descriptions that convert browsers into users.

## When This Skill Activates

- User needs to write initial App Store description
- User wants to improve existing description
- User is preparing for a major update
- User asks about promotional text or What's New

## Information Gathering

Before writing, ask about:

1. **App Basics**
   - What does the app do? (one sentence)
   - Who is it for? (target audience)
   - What problem does it solve?

2. **Key Features**
   - Top 3-5 features
   - What makes it unique vs competitors?
   - Any awards or recognition?

3. **Social Proof**
   - Number of users/downloads (if impressive)
   - Notable reviews or press mentions
   - Any partnerships or integrations?

4. **Tone**
   - Professional / Casual / Fun / Technical?
   - Brand voice keywords?

## Output Format

Generate all three text types:

### 1. Promotional Text (170 characters)
- First thing users see
- Should create curiosity or urgency
- Can be updated without app review
- Good for seasonal/sale messaging

### 2. Full Description (4000 characters max)
Structure:
```
[Opening Hook - 1-2 sentences, problem/benefit focused]

[Key Features with emoji bullets]
• Feature 1 - benefit
• Feature 2 - benefit
• Feature 3 - benefit

[Social Proof paragraph - optional]

```

## Best Practices

### Do's
- Lead with the biggest benefit
- Use short paragraphs (2-3 lines max)
- Include relevant keywords naturally
- Use emojis sparingly for scannability
- End with clear call-to-action
- Mention if there's a free trial/tier

### Don'ts
- Don't start with "Welcome to..."
- Don't use ALL CAPS excessively
- Don't mention prices (they change)
- Don't claim "#1" or "best" without proof
- Don't mention competitors by name
- Don't include URLs (they're not clickable)

## Examples

### Promotional Text Examples

**Productivity App:**
```
Transform chaos into clarity. The task manager that adapts to how YOU work.
```

**Weather App:**
```
Know before you go. Hyperlocal forecasts down to your street corner. ⛅️
```

**Finance App:**
```
Your money, finally making sense. Budgeting that doesn't feel like homework.
```

### Description Opening Examples

into organized action plans in seconds.
```

## Localization Tips

When localizing descriptions:
- Don't just translate—adapt to cultural context
- Research local competitors' descriptions
- Adjust feature emphasis by market
- Use native speakers for review
- Consider character limits in other languages (German expands ~30%)
