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.

Letterloop is a fun way to have a group newsletter without the work. You pick the questions for your group to answer, then Letterloop creates a fun and beautiful newsletter with everyone's replies. All you need is to do is invite your people!
How does Letterloop work?
We crafted a set of questions designed to spark fun and thoughtful replies. The questions range from updates about your week to thoughts on identity, life stories, and personal philosophies.
Each newsletter cycle, we'll suggest a few questions for you. You can always swap questions or add your own. Plus, members of your newsletter can ask their own questions that you can include too.
