Guqin Tuner Pro

Guqin Tuner Pro is a paid tuner for the seven-string guqin. There are no ads, subscriptions, or in-app purchases. Only the verified standard tuning, zhengdiao, is included. Its open-string relation is about C–D–F–G–A–C–D. Absolute pitch varies by instrument, strings, and school. Target pitches are calculated from the A4 you set (415–466 Hz, 440 Hz by default) and are a tuning guide, not a claim of one historical pitch. Other traditional tunings will be added only after their pitches are checked against reliable sources. On the Tuner tab the needle shows flat, in tune, or sharp. Tunings shows how the seven strings relate to zhengdiao. Sounds plays a soft reference tone. Audio is analysed live on your device and is never recorded, saved, or uploaded. For iPhone, iPad, and Mac.
