Which one is for you

Pick AppSigma if

  • Fits if you work in Claude, ChatGPT or Cursor and want App Store ranks inside it
  • Works for small teams tracking up to 10 iOS apps on one $19.99 plan

Look elsewhere if

  • Skip it if you have an Android app, as Google Play isn't covered
  • Tight if you're staying free, since the free plan tracks 1 app and 5 keywords in one market
  • Watch out: paid plans list unlimited keywords, but daily positions are described as covering up to 500 per app
  • Watch out: only monthly prices are shown, with no discount for paying yearly
  • Pricey if more than 3 people need access, since 10 team members means Pro at $49.99 a month

Pick ASO.dev if

  • Fits if you spend a lot of time in App Store Connect and want bulk edits across localizations
  • Works for developers tracking large App Store keyword lists without per-keyword limits

Look elsewhere if

  • Skip it if your keyword work is on Google Play, as its ASO analytics is listed as not yet available
  • Not for you if you want it in a browser, as there's no web app, only installed apps
  • Tight if you want time to try it, as the trial lasts 3 days
  • Tight if you're an agency, as Indie isn't meant for agencies and keeps 30 days of data with no export
  • Watch out: every plan is per seat, Console has no keyword tracking, and the API is in alpha

    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.
