Which one is for you
Pick ASOTool if
- Fits if you're an indie developer researching keywords for both stores on a small budget
- 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
Pick RespectASO if
- Fits if you're an indie iOS developer who wants keyword research without a subscription
- Makes sense if you'd rather keep your research data on your own Mac
Look elsewhere if
- Skip it if you ship on Google Play, as it researches the iOS App Store only
- Not for you if you want Pro on an Intel Mac, Windows or Linux, as it needs Apple Silicon and macOS 12 or later
- Watch out: Pro's AI tools need your own paid LLM key or a local model, whose speed depends on your Mac
- Watch out: Pro is one payment that doesn't renew, business purchases are final, and the price shows in local currency

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.
