aso.best

aso.best is keyword research for App Store and Google Play developers, built on the stores' own numbers instead of modelled "search volume". Paste any competitor and in two minutes you see every phrase it ranks for, the popularity score Apple gives advertisers, first-page difficulty, and which phrases sit in its hidden keyword field. Follow your own apps and get positions, ratings and new reviews every morning. Then put the winning phrases straight into App Store Connect: name, subtitle and keyword field, edited per language with Apple's character counters. An assistant with 19 tools does all of this from a chat, and the same tools run as an MCP server inside Claude, Cursor and ChatGPT, free on every plan.
