Tuner (The Twom)

The Twom’s Tuner is an open-source Android instrument tuner with visual pitch information. It is useful for practice, instrument setup and quick checks away from a studio. Its role is pitch estimation rather than calibrated acoustic-level measurement. Select suitable settings for the instrument and use a quiet environment when the device microphone struggles to identify a stable fundamental.

A useful display begins with a clear question and appropriate measurement settings. Confirm important observations through listening or a second check, and document calibration where absolute measurements matter.
