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.
RIA DigiDoc is an application that allows you to digitally sign documents, verify the validity of digital signatures, encrypt and open, save and share files on mobile devices using the Estonian ID card, NFC, mobile-ID and Smart-ID. Encryption / decryption via RIA DigiDoc only works with an Estonian ID-card via NFC. Containers with the .ddoc, .bdoc .asice and .cdoc extensions are supported.
With the RIA DigiDoc application, you can check the information and validity of ID card certificates and change PIN and PUK codes. The “My eIDs” menu displays the ID card owner’s data and ID card validity information. This information is only visible when the ID card is connected.
