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 the second in the "pilot helper" series is aimed at helping you out with all those pesky acronyms and contractions.
This application is for professional and private Pilots. It is a compact search tool used to help with NOTAM / Weather Contractions (Acronyms) either inflight or on the ground.
On the Ground this app helps you interpret complex NOTAMs and un-decoded METARs/ TAF’s / Area Forecasts, etc..
As a pilot you often review your NOTAMS again in the air when close to your destination as a reminder, it is impractical to go looking up contracts at this stage of the flight but this app makes that simple.
Simply type in the first few characters of the contraction and the list will narrow down showing you the definition you need to understand the information you have.
E.G. if looking for the meaning of "PAEW" you just type in part of the contraction "pa" and you will see the list narrow down to similar contractions with the definition adjacent to it in this case “Personnel and Equipment Working”.
What’s new
Release notes for the latest version, as written by the developer.
New Feature to allow contractions to be feedback to the app community
