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.
Rassel – Pocket Shaker transforms your iPhone to a shaken percussion instrument. Just pick up the device and shake it. This initial version comes with four different instruments: Egg, Shaker, Tambourine and Bells. Just swipe the screen to change between them.
Unlike similar apps, Rassel is based on a unique audio rendering engine that accounts for continuous velocity changes based on how the sampled instruments are agitated. The device’s gyroscope is directly mapped to this velocity which makes any movement sound the way a real instrument would. We’ve tried to fine-tune the app to be as lifelike as possible, both in sound and handling response. We think we got pretty close.
Features:
- Instruments: Egg, Shaker, Tambourine and Bells
- Choose between loose, normal or tight setting
- Loudness boost option
