Guzheng ´

Sweep your thumb across 21 real recorded strings and hear a guzheng answer.

Guzheng turns your iPhone into a 21-string Chinese zither you can actually play.

Every note is a real recorded sample, not a synth tone. Glide across the strings and you get the sweep that makes the guzheng instantly recognisable; press a string and the pitch bends the way it does on a real instrument.

EIGHT STRINGED VOICES Guzheng and Koto are free from the start. Unlock Zhuque, Qionghua, Zokuso and the Vietnamese Zither, or go Premium for Pipa and Banjo. Each one has its own sample set, not a filtered copy of the last.

BUILT FOR FINGERS Pinch the note column with two fingers to zoom in when you want fewer, wider strings, then scroll to the register you need. Jianpu numbers on every string tell you where you are.

FIVE BOARD STYLES Blue cloud, gold wave, ink cloud, crimson swirl and jade mist. Each is drawn in code so it stays sharp on any screen, and the body and side rail change colour to match. Add drifting petals and set how heavy the fall should be, or use a photo of your own as the board.

TUNE BY EAR OR BY METER The built-in tuning fork listens through the microphone and shows how far each string sits from pitch. A metronome with adjustable tempo and time signature keeps your right hand honest.

RECORD AND KEEP IT Capture what you play as MIDI, or record straight through the microphone. Rename, share, or import MIDI files from anywhere on your device and play them back on the board.

PLAY ALONG Import a backing track from a video in your photo library or an audio file in Files. The app pulls the audio out and plays it while you perform over the top.

Available in 18 languages. Premium is a single one-time purchase, not a subscription.
