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.

If you're not sure what to do with this app,
try recording the word "Famima" and then playing it in reverse.
(By the way, Famima (short for FamilyMart) is a Japanese convenience store chain.)

Appreciate your reviews.
If you haven't already and you like the app,
please leave a review.
Your feedback is valuable to me!

If you're experiencing difficulty with recording, try restarting your device.
If you're using headphones, ensure they are connected *correctly*; this may resolve the issue.
If not, you could give me an email via App Support → Scroll down to Contact.

Thanks!
