GalileoTuner

Galileo is a music tuner.
Earth mode shows the pitch by chromatic scale in circle.(Please set the microphone on).
Jupiter mode shows detailed pitch in smaller circle.
When the red mark in the opposite side of "50" aligns with the red arrow bellow the smaller circle,
it produces equal temperament pitch.
The two smaller red marks on both side of the red mark shows just intonation of major 3rd (-) and minor 3rd (+).
