Pick ASOTool if

- Works for agencies keeping one shared workspace per client app on Pro
Look elsewhere if
- Skip it if you want reviews, ad monitoring or download estimates, as it covers keywords and metadata only
- Watch out: Google Play popularity is always an estimate, since Google publishes no search volume
- Tight if you're staying free, as Free allows 10 searches a day, 1 app and 10 saved keywords, with no Optimize
- Not for you if you want yearly billing, as Pro is sold monthly only
- Watch out: the 7-day trial takes a card at checkout, and there are no integrations or API on record

- Works for people tracking thousands of App Store keywords who want one flat yearly price
Look elsewhere if
- Skip it if your app is on Google Play too, as the pages read only cover Apple's App Store
- Not for you if you work on Windows or in a browser, as it runs only on Macs with macOS 14 or later
- Watch out: ranks only update while the app is open on your Mac, and a license covers one Mac at a time
- Tight if you stay free, since the free version tracks 10 keywords without popularity or difficulty
- Watch out: billing is yearly only at $108, and suggestions come from Astro users' searches, so niche apps may get few

Key features
ASOTool
- Keyword discovery
- Start from a keyword, an app name or a store link and expand through store autocomplete into related terms, each scored for popularity and difficulty.
- Marked estimates
- App Store popularity comes from Apple Search Ads where Apple publishes a figure; modelled values, including every Google Play term, are marked with a ~.
- Rank tracking
- Ranks are read from live search results in the storefront you pick, with 7, 30 and 90-day change and a history that shows gaps on unmeasured days.
- Optimize
- Reads the live listing and proposes a title, subtitle and keyword field within each store's character limits, scored against your keyword list. Pro only.
- Team workspaces and export
- Pro adds shared workspaces with email invites; keywords, scores and rank history export to CSV, and a workspace downloads as JSON.
Astro
- Popularity and difficulty scores
- Popularity comes from Apple Ads; difficulty is Astro's own estimate of how hard it is to reach the top 10. Both need the paid license.
- Daily keyword rank tracking
- Keywords are re-checked every 24 hours while the app is running, with position changes and a day-by-day ranking chart.
- Keyword suggestions
- Lists keywords an app ranks or has ranked for, drawn from searches made by all Astro users, so new or niche apps may get few suggestions.
- Competitor keywords
- Paste a competitor's App Store link to see the keywords it ranks for in a chosen store, sorted by popularity and difficulty.
- Ratings across stores
- A ratings view sums ratings from every country's App Store, with daily changes, per-store counts and a chart over time.
- MCP server (beta)
- A local MCP server, switched on in Settings, lets AI assistants such as Claude, Cursor and VS Code Copilot query Astro's data.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
