See where your app really ranks.
AppSigma tracks your App Store keywords every day, watches your competitors, and turns your reviews into a to-do list. In a dashboard, over the API, or straight into your AI agent.
Free account to browse any app's data — tracking is part of the paid plans.
The actual keyword tracker — not an illustration.
keywords.daily
Track every keyword that matters — and the ones your competitor took.
Positions for up to 500 keywords per app, recorded daily after the 02:00 UTC crawl. Movers, best-ever positions, and popularity & difficulty scores on every row.
The keyword gap shows where a competitor ranks and you don’t — sorted by how winnable each keyword is, with the SERP top-5 inline so you see who you’re up against.

reviews.ai
Your reviews already tell you what to fix next.
AppSigma reads every review, classifies sentiment, and extracts the topics and keywords behind it — so “3.8 stars” becomes “24% of 1-star reviews are a billing bug.”
Every insight links back to the actual reviews, filtered in place. No sampling, no vibes — the whole corpus.
charts.history
Chart positions across every storefront.
Where your app sits in the top charts — overall and per genre — for every country, with 180 days of history and your releases marked on the timeline.
Ratings come with it: histograms per version, so you know whether the last update moved the needle or broke something.
api + mcp
The same data, one command away.
Everything in the dashboard is also a REST API and an MCP server with 21 tools. Point Claude, Cursor or any MCP client at it and your AI researches apps, reads reviews and pulls chart history on its own.
The demo key works without an account. A real key comes with 1,000 free credits — one credit is one row of data.

> what do the 1-star reviews of my competitor complain about?
