Which one is for you

Pick AppStoreSpy if

  • Fits if you're hunting for app niches from install and revenue figures
  • Works for sales teams building lists of app developers to contact

Look elsewhere if

  • Tight if you browse a lot, as plans cap app views a day at 100, 1,000, 10,000 and 50,000
  • Pricey if you need the niche finder and keyword analysis, which start at Pro, $79 a month on yearly billing
  • Skip it if you research the App Store, as the Chrome extension works on Google Play only
  • Watch out: the pricing table lists API credits on every plan, but the API page says it's Business-only
  • Not for you if a team shares it, as extra users and CSV export come only with Business, $159 a month billed yearly

Pick ASOTools if

  • Fits if you're an indie developer who wants keyword research on both stores without paying
  • Works for checking a rival's keywords and download trend before a launch

Look elsewhere if

  • Watch out: the site says all features are free, but its terms still describe paid subscriptions
  • Tight if you work in markets beyond 46 countries, as that's where keyword data stops
  • Watch out: data is refreshed daily only for popular charting apps and apps you add to your account
  • Skip it if you research the App Store in your browser, as the extension works on Google Play only
  • Not for you if you need integrations or an API, as none is on record

    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.
