Tempered third. In equal temperament, a major third is 13.7 cents wider than a pure third, so an open chord beats. Turn on Tempered third, and the open tuning rings clean.
The Triad tuner tunes a guitar string by string. The paper roll draws the pitch, and each string gets a check mark when it is in tune.
Demo readings. On your iPhone, Triad listens to your instrument.
Metronome

Tone generator
Tune by ear.
Play any note, or any frequency from 20 Hz to 20 kHz, as a sine, triangle, sawtooth or square wave. Tap a string to hear its note, like a pitch pipe. The tone fades in, fades out and glides to each new pitch, so it never clicks.

- 20 Hz to 20 kHz
- Waveforms
- Sine, triangle, sawtooth, square
- Loudness
- The same for each waveform
