String Tuner — Guzheng, Guqin & Chromatic Tuner + Metronome

String Tuner is a precise, easy-to-use tuning app made for traditional Chinese string instruments, with a full chromatic tuner and a practice metronome in one place. Pluck a string, watch the dial settle, and your instrument is in tune in seconds. No account, no sign-up, and your sound never leaves your device.

FOUR TOOLS IN ONE APP

• Guzheng tuner — 21 strings and five common tunings (D, G, C, F, A). Auto mode detects the string you pluck; manual mode lets you tune one specific string.
• Guqin tuner — 7 strings and three classic tunings: Standard (F), Slow 3rd string (C) and Tight 5th string (B♭).
• Chromatic tuner — full-range pitch detection for any instrument, with adjustable A4 calibration.
• Metronome — 10–208 BPM, tap tempo, time signatures, subdivisions (quarter, eighth, triplet, sixteenth), accent on the first beat, four click sounds including a spoken count, and a sleep timer.

MADE FOR EVERYDAY PRACTICE

• Cents-accurate readout — see at a glance whether a string is flat, sharp or in tune, with a plain "tighten / loosen" hint right on the dial.
• Reference tones — play the target pitch of any string before you tune it by ear.
• Temperaments — equal temperament and Pythagorean tuning for guzheng; equal, Pythagorean and just intonation for guqin.
• Sensitivity control — raise it to catch soft plucks, lower it in a noisy room.
• Remembers your setup — A4 reference, sensitivity, selected tuning and metronome settings are saved automatically.
• Layouts for every player — landscape and portrait instrument views, plus home-screen shortcuts that jump straight to a tool.

A METRONOME THAT KEEPS GOING

Set your tempo and the metronome keeps time while you practice, even with the screen off or another app open, thanks to background playback and its notification. The sleep timer stops it automatically after 1 to 360 minutes.

PRIVATE BY DESIGN

• Microphone audio is analyzed on your device in real time and then discarded — nothing is recorded, saved or uploaded.
• No account and no personal data collection.
• Tuning and metronome work without an internet connection.
• The microphone is listed as optional hardware: the app still installs on devices without one, and the metronome keeps working if you decline the permission. (Tuning needs the microphone.)

FREE EDITION

The Free edition is supported by banner and interstitial ads from Google AdMob. If you prefer a completely ad-free app, look for String Tuner Pro.

Strings, pitch and rhythm — one small app for all of it. Happy practicing!
