aso.best reads your competitors' App Store keywords from Apple's own numbers, and it is built by a developer who needed it himself

Most ASO tools sell you a search volume number that nobody outside the company can check. aso.best takes the opposite position. Its maker, Primož, says every number is either Apple's own popularity score or arithmetic on it, and when Apple has nothing, the tool shows a dash. That is a small promise, but in a category full of confident guesses it is the kind that makes you trust the rest of the screen.

The headline feature is the competitor read. You paste the app ranking above you, wait a couple of minutes, and get the phrases it ranks for, with difficulty, its position, and a flag on phrases that can only be coming from its hidden 100-character keyword field. From there you can track your own positions daily across both stores and edit your listing in multiple languages.

Who it suits

Indie developers and small studios who do their own ASO and have balked at enterprise pricing. The free tier is enough to read a few competitors and see if the data is useful. Paid plans are modest and organised around what you are trying to do, and agencies get a tier with seats, client PDFs and branded reports. If you live in Claude or Cursor, the MCP server means you can ask keyword questions in a chat.

The best way to start

Start on the free plan and point it at the one app sitting just above you in search. A competitor read takes a couple of minutes, and the phrases flagged as likely hidden keyword field terms are the fun part: strong hints, drawn from ranking behaviour, about what that rival quietly decided to target. Pick the handful worth chasing, add them to tracking, and check the morning numbers for a week. If you already work in Claude or Cursor, the MCP server on paid plans turns those same questions into a quick chat.

Honest numbers, a friendly price, and the maker himself answering the email.
