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.
Charles is a bloodthirsty train, and you need to destroy him.
Navigate a massive play area in your trusty old engine: These winding tracks are treacherous, so you'll need to plan each mission carefully. Be wary when traveling on foot, or switching the track's direction; Charles might be waiting for you.
Upgrade your train to fit your needs: Go looting or complete missions to find "Scraps", which can be used to turn your train into a death machine on wheels.
Get help from the townspeople: Help out the settlers in return for high powered weapons, and other items vital to Charles' destruction.
Fight Charles to the death: Complete the main questline, and summon Charles to a mortal duel. If you’ve gained enough strength, firepower, and skill, Charles may finally meet his match.
