aso.best
aso.best is a free App Store Optimization (ASO) keyword research tool that derives its data directly from Apple's App Store and Google Play rankings. It focuses on revealing the actual phrases apps rank for, including the hidden keyword field that is not visible on store listings. The platform provides competitor keyword analysis, daily position tracking, visibility scores, and a listing editor for translating and editing App Store Connect and Google Play metadata across languages. The service includes a natural-language assistant that can run tools from a sentence, an MCP server for use inside Claude, Cursor, and Codex, and agency-oriented features such as seats, client PDFs, and API access. It also offers a suite of free tools for keyword insights, competitor finding, niche analysis, top charts, movers, market index, algorithm changes, character limits, and a keyword field builder. aso.best is positioned as a practical, data-driven alternative for ASO professionals who want to work from the stores' own numbers rather than estimates. Its public audit pages and visibility score make it easy to share app performance with stakeholders, while daily tracking covers positions, ratings, and reviews on both major mobile app stores.
