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.

* 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:

Vertical line – Represents a "chord line," commonly used for major plucks, minor plucks, and chords.

Wavy line – Represents a "glissando line," commonly used for ornamental notes, glissando, double thumb, heavy thumb, etc.

Fine dashed line – Represents a "note group." All notes connected by fine dashed lines form a note group, which may consist of common fingering combinations (alternating thumb and middle finger, four-note patterns, etc.), grace notes, triplets, arpeggiated chords, rhythmic patterns, etc.

Horizontal thick dashed line – Represents a "tremolo line," indicating the start and end times of the tremolo.

√ Full 21 strings.

√ Automatically play "Shake" technique (自动摇指) when you move your touch on the string horizontally.

√ Smart snapping to the correct pitch grid when moving the pitch slider.

√ "Dian Yin" Effect (点音/Tap Pitch) : tap the pitch slider after plucking a string to create the "Dian Yin" sound effect.
