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.

FANCY FEATURES YOU’LL WANT TO BRAG ABOUT TO YOUR FRIENDS
Audiobooks HQ even does neat tricks like adjusts the speed, slows down or speeds up playback in 40 increments (without affecting pitch!), and even sets a sleep timer when it's time for bed.
BONUS: ACCESS 109,000 EPISODES OF OLD TIME RADIO, TOO!
It's the best radio dramas of the 1930's, 1940's, 1950's and more. Because what's modern technology without a little old-school entertainment?
