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.

The International Certificate of Competence App is an essential learning and revision aid for anyone taking the ICC test. Many European countries require skippers of visiting yachts to hold a Certificate of Competence. While most experienced skippers are able to handle their boats with confidence, there are rules and regulations that all skippers should know. For those unsure of what the test entails, this app provides the answers to questions such as:

What will I be asked about?
How much of the basics have I forgotten?
How many of the regulations have I never really known?

The International Certificate of Competence App aims to answer exactly these types of questions. The syllabus is explained in detail, and helpful revision notes and self-test questions at each stage ensure the information is being absorbed. With this app to hand, users will feel ready to take the ICC test with confidence.

Features and Benefits:
A practical learning and revision tool
Everything a skipper needs to know about taking the ICC test
Includes the International Regulations for Preventing Collisions at Sea
