Three layers
Apple first. Then what we measure. Then what we calculate.
Straight from Apple.
From your App Store Connect and Apple Ads accounts, and from the public App Store. We show it as it is.
- Downloads, revenue, conversion
- Ratings and reviews
- Apple Ads campaigns
- Competitor texts, screenshots, prices
Checked by us. Every day.
We search the App Store ourselves and read the results. What you see really happened in App Store search.
- Your rankings
- The top apps per keyword
- Which words find your app
- Rank history
Our own models.
Built on the two layers above and checked against Apple's own numbers. Always marked, never hidden.
- Popularity, when Apple has no number
- Difficulty
- Downloads per keyword
- Chance and visibility scores

Our promise
Honest numbers. No guesswork sold as fact.
No made-up search volumes
Apple doesn't publish search counts. So we don't invent them.
No bought data
No phone panels, no tracking SDKs. Only Apple and the App Store.
Calculated means marked
If our model made a number, the app tells you.
Checked against Apple
Our models are compared with Apple's real numbers, again and again.
Why our recipe stays private.
Our models took a lot of work. They are what makes Fermium100 more than a guess. So we show you where every number comes from, not how we cook it.
