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.

* Differences between this version and the Pro version: The Pro version offers more advanced features such as song recording, tuning, multiple instrument sounds, background and string color settings, and a metronome. The Follow Play songs in both versions are identical and are released simultaneously.
iGuzheng's innovative "Follow Play" feature allows even complete beginners to effortlessly play professional Guzheng pieces!
Guzheng is a Chinese plucked zither that dates back to 500 B.C. It is rich in playing techniques. The performer plucks the strings with his right-hand fingernails, while his left-hand fingers apply pressure to the strings to execute vibratos, slides, and other embellishments , as well as occasional plucking techniques.
iGuzheng supports many playing techniques, like an acoustic Guzheng:
- Playing techniques for Right Hand:
Pluck, Glissando, Tremolo (Shake/摇指), Automatic Tremolo, Overtone
- Playing techniques for Left Hand:
Pitch Slide, Small Vibrato, Big Vibrato, Tap Pitch (Dian Yin – 点音)
Main Features:
√ Follow Play: iGuzheng's original "Follow Play" feature combines Guzheng playing symbols with string positions to provide real-time playing prompts, allowing even complete beginners to effortlessly play professional Guzheng pieces!
** Supports setting to follow only the right-hand part or both hands!
** When following only the right-hand part, iGuzheng will automatically play the left-hand part for you!
** Can be set to automatically play left-hand pressing actions: pressed notes, glissando, vibrato, etc.
[Appendix] Meanings of various lines in Follow Play:
