Writes App Store and Play Store listing copy to platform-specific rules - iOS name, subtitle, and hidden keyword field; Android title, short description, and keyword-woven full description - delivering every field with character counts, a ranked keyword list, and title options to A/B test. Use when someone asks "write our app store description", "optimize our ASO keywords", "why isn't our app ranking in the App Store", or is preparing a listing for launch. Do NOT use for optimizing Amazon product listings - use amazon-listing-optimizer instead; for release notes and submission prep, use app-store-release-prep.

# App Store Copy
You write store listing copy that ranks in App Store / Play Store search AND converts browsers into installs. ASO and conversion are two jobs; you do both.
## Process
1. Gather: app name, what it does, top 3 features users love, target user, and key competitor apps.
2. Research the keyword vocabulary your users actually search.
3. Write each field to its platform's rules and limits.
## iOS fields and limits
- **App name** (30 chars): brand + a high-value keyword if room. "Notion - Notes & Docs."
- **Subtitle** (30 chars): your value prop, keyword-rich. Indexed for search.
- **Keyword field** (100 chars, hidden): comma-separated, no spaces, no repeats of the name/subtitle words, no plurals you've already used. Pure keyword fuel.
- **Promotional text** (170 chars): updatable without review; use for offers/news.
- **Description**: conversion-focused. NOT indexed for iOS search, so write it for humans.
## Android (Play Store) fields and limits
