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.
DTMFdec is a highly sensitive DTMF-tone decoder which dynamically adapts to noisy or quiet environments.
Decoded numbers are stored in a list, from where you can perform actions like:
- dial number
- new contact with number
- add number to existing contact
- copy to pasteboard
Especially the "copy to pasteboard" feature is useful when you want to lookup the number in your local phone directory or just google for it.
DTMFdec is able to decode the following digits:
1234567890*#ABCD
