# ASOMaster

> ASOMaster is a desktop app (macOS 13+, Windows 11 beta) for App Store and Google Play optimization, made by Cressu OÜ (Tallinn, Estonia). It checks keyword ranks in 54 App Store and 53 Google Play markets, in each market's own language; shows real popularity from the user's Apple Ads or Google Ads account next to its own estimates of volume and difficulty; drafts, compares, localizes (49 languages) and publishes store listings; pulls store analytics; sends rank alerts by app notification, Slack or email; runs its AI features on the user's own Claude Code, Codex, OpenCode, Ollama or Anthropic API key; and includes an MCP server so AI agents can drive the app. Data stays on the user's computer. ASOMaster Pro costs €15.99 per month or €49 per year plus VAT.

Key facts:
- Volume and difficulty are estimates modelled from store search results; "popularity" is real data from Apple Ads / Google Ads or an imported file, shown separately.
- Publishing writes a new App Store Connect version or a Google Play edit only when the owner starts it; it never submits for review.
- One license key works on 2 computers; the app works offline up to 7 days between license checks.
