Type your app's name and up to three things people would search for. This checks where you actually rank in the App Store right now, and reads your listing against the fields Apple indexes.
Live against Apple's public Search API. No signup, no key, nothing stored. It also tells you the six things it cannot see - starting with the one that matters most.
Live App Store search ordering for the storefront you picked, at the moment you asked. A rank is not a download - it is the chance of one.
Read from the fields Apple publishes. Severity 1 is most urgent.
Named rather than quietly dropped. The first one is the biggest on-page lever on iOS, and no external tool can read it - including the ones that charge for it.
Every app ranks first for its own name. That number feels like proof and measures nothing: the only people typing it already know you exist.
The search that matters is the category one - the words somebody types when they have the problem and have never heard of you. That is where a new app is usually nowhere, and it is invisible from inside App Store Connect, which reports the traffic you got rather than the traffic you were never in the running for.
Most ASO advice starts at step three, because that is the part you can see without data.
This reads what Apple publishes. It cannot see your 100-character keyword field, your subtitle, your installs, your conversion rate, or anything at all on Google Play. Those need App Store Connect access, which needs a key only you can issue. A public API produces evidence about the outside of your listing. The inside needs your login.
