Start here — it depends on one thing.

Whether your app is already on the App Store changes what we can measure. Pick the one that's true and you'll get the right thing — not a form that can't answer you. Either way it's free, and either way you can just read the data without filling anything in.

Is your app already on the App Store?

Live = we can measure your reviews. Not live = we can only tell you about the category you're about to enter. Both are free; they're different products.

App Store link

Any App Store link works — we read the numeric ID out of it.

Your email

We send the link here. No password, no account, no newsletter.

Instant if we already have your app — we refresh the tracked set daily, so most requests are answered immediately.
Otherwise within a few hours, not instantly. The crawl runs on a schedule. We'd rather say that than show you a spinner that's lying.
Counts and short functional phrases only — we never redistribute review text, usernames, or avatars.
