Per-keyword competitor analysis includes up to 25 competitors, with ratings, review velocity, market age, publisher diversity, and tier analysis. It uses publicly available metadata, ratings, and reviews from Apple App Store and Google Play. ASOStacks also offers an MCP connector for Claude, and says no API keys are needed.

ASOTrendHQ
ASOTrendHQ organizes public Apple App Store and Google Play information into tools for keyword, ranking, category, and competitor research. Users can investigate iOS and Android keywords from available United States search observations, filtering by phrase, observed rank, or modeled difficulty. Keyword shortlists can be saved in a browser and exported as CSV with supporting evidence. Competitor analysis compares collected keyword footprints to identify terms for further investigation. Historical ranking movement is displayed from collected data, with a recommendation to validate it against store-console results. Popularity, difficulty, search volume, traffic potential, and opportunity scores are model estimates from public store data, not official Apple or Google metrics. Records show their own refresh timestamps, while collection schedules differ. Coverage and rankings vary by app, country, and time; jobs may be delayed, incomplete, or temporarily unavailable. The service is free during active development, every feature is currently free, and no credit card is required. It is an independent project unaffiliated with Apple or Google.
