PitchCompass 2 For iPhone and iPad
See pitch as you hear it.
Tune an instrument, practise intonation, train your ear, or identify a tone while transcribing. PitchCompass puts note, octave, cents, and frequency at the center of a clear circular display.
Reference tones and the metronome are free—no microphone required.
A clearer chromatic tuner
Your pitch, centered.
PitchCompass analyzes microphone input on your device and places the detected pitch on a 12-note chromatic compass. A precise marker shows where the pitch falls, while the familiar three harmonic rings show agreement around the tone.
The center readout keeps the note, octave, signed cents, and frequency together. Follow a sustained note in the cents-history trace, or switch to the microphone waveform familiar from version 1.
