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.
The Government of the Grand Duchy of Luxembourg has developed a mobile app, called ' LU-Alert ', to alert the population in case of an emergency and share information about risks by smartphone. The app supplements the alert system operated by the Government and forms part of a general approach for increasing public awareness and understanding of risks and protective measures.
The app enables the Government to broadcast alerts about major incidents, natural hazards or imminent danger. It allows users to be alerted by a notification on their smartphone in the event of a situation that affects public safety. It is possible to choose types of risks / proximity / places of interest settings to display personalized alerts.
As a preventive measure, information on appropriate behavior to adopt and the various emergency response plans are also available via the app.
