App Description Writer

Generate compelling App Store descriptions that convert browsers into users.

When to Use

  • 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?
  1. Key Features
  • Top 3-5 features
  • What makes it unique vs competitors?
  • Any awards or recognition?
  1. Social Proof
  • Number of users/downloads (if impressive)
  • Notable reviews or press mentions
  • Any partnerships or integrations?
  1. 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]
 
[How it works - brief explanation]
 
[Call to action]
 
[Support/contact info]

Thank you for your feedback!

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

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%)
