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.
David Stewart, Australia’s most renowned wildlife sound recordist, presents a unique bird call app that contains over 3800 high quality calls covering 725 species of birds. This comprehensive collection of bird calls is the result of over 40 years of sound recording and will be a valuable tool for anyone wanting to identify Australian birds.
The app contains a taxonomic and alphabetic listing of birds with the ability to switch between IOC 10.1 and Clements World taxonomies with a tap of a button.
There is a small thumbnail image for most species and a concise descriptive text for each species.
The calls display a map of the area that the sound was recorded and also an oscillogram representation.
We invite any comments or suggestions for this new and unique bird call app. We look forward to hearing from you at [email protected]
