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.
ASA’s Sailing Challenge (for iPhone/iPad) includes six fun, easy-to-use modules that unlock the mysteries of sailing. Learn Points of Sail, Apparent Wind, Sail Trim, Tacking and Jibing, Rules of the Road, and Docking. Then, put it all together when you sail around a course against the clock in the Sailing module.
Sailing Challenge combines the most innovative thinking in the digital education field with ASA’s experience in teaching sailing to create a game that lets players climb aboard, take control of the tiller in one hand and the mainsheet in the other, and sail off on a virtual sea of fun. When the ASA says the fun starts here, we really mean it!
