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.
This app is designed to help you learn and differentiate the shades in meaning and usage between synonyms and antonyms
For example: ability and capability are synonyms. However, there is fine distinction between them. If you have an ability, it means you know how to do something. If you have a capability, it means you have the power to do something. Buying uranium gives a country capability of making nuclear weapons, but first they need scientists with the ability to do the work.
Each word will be explained in details with information about usage and origin.
You "alleviate" your pain, but "assuage" your unpleasant feeling.
If you are preparing for GRE, GMAT, SAT, ACT, IELTS, TOEFL, etc. this app will be very useful to you. It helps you to expand your vocabulary and improve your reading skills.
