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 'YO YO Endurance Test' provides an important instrument for determining the level of physical efficiency of an athlete.
The physical capacity is evaluated quickly and easily by placing two cones spaced 20 meters each other.
The athlete has to run at full speed from one cone to another and then return again on the first cone. This path must be repeated for six times without any break, and get the split times every time the athlete passes on the first cone.

This application will track all the split time and at the end will be calculated two parameters that determine the outcome of the test. More these values are low and better will be the athlete's performance.

Basically the final result is given by a mathematical formula that processes the delta between the averages of the last two split times and the first two split times and thereby the athlete's ability to maintain its maximum speed for a certain period of time.

The second value obtained on completion of the test, is the first result considering also the total time of the test.

The 'YO YO Endurance Test' can be used to determine the level of athletic in all sports (football, running, basketball, volleyball, cycling, tennis etc.)
At the end of the test you can get for each athlete the final result (eg. "Above average" or "Poor") and the Vo2Max estimate
