HarmoTuner
Music
Free · Designed for iPad. Not verified for macOS.
HarmoTuner is a tuner and metronome designed for tuning with other players and finding a more natural, resonant pitch together.
In addition to single-note pitch detection, HarmoTuner lets you choose a target chord and see where each chord tone should sit for a just-intonation sound. You can adjust the reference pitch, temperament, input sensitivity, and lock sensitivity to match your practice setup.
The built-in metronome supports BPM, meter, and subdivision settings, so you can check pitch and practice tempo in one app.
Audio analysis is performed on device. HarmoTuner does not save recordings or send audio data outside your device.
