Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

About this app
Text from the App Store listing.
Grandpa always was a little eccentric. A fantastic engineer, he was always buried in his work, always coming up with new ideas and inventions that as a child held you wide-eyed in awe.
Now, after many years, you return to the house that holds so many fond memories for you, with a promise from Grandpa to show you something truly amazing. You can't even begin to imagine what it could be!
It's a dark and stormy night as you arrive at Grisly Manor. The rain beats down hard, lightning flashes in the sky as the sound of thunder fills your ears. You already feel a little creeped out, but when you make your way inside, the house is curiously empty. Grandpa is nowhere to be found!
But his presence is everywhere.
Familiar objects have been re-engineered to create puzzles for you. Clues abound, and as each puzzle is solved, the solution to others present themselves. As well as new puzzles, of course.
Grandpa obviously spent a lot of time making sure that nobody could solve the myriad of puzzles strewn about the house. Nobody but you, his favorite grandchild...
