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.
COBISS Plus is a mobile app that allows you to access and search the library catalogue, view information about materials and their availability for loan at libraries included in the COBISS system. The app also allows you to search specialised databases and university portals.
In COBISS Plus, users who have created a COBISS account and added a library membership can:
- reserve materials
- borrow e-books and audiobooks
- request materials for interlibrary loan and cancel such requests
- view items checked out at their library and renew loan periods, cancel reservations, or return e-books early
- renew their membership
- view and pay outstanding fees
- view their loan history
Registered users can add records of interesting materials to their favourites or shelves, save search requests, set a default library for searching, set the number of search results displayed, specify the default library membership in their COBISS account, etc.
Users who are not yet members of the library can also join the library.
