HOW TO USE:
To change the pitch, tap on the buttons above the '440.0' and edit its value as desired.
Green position indicator:
Fine tuning resolution: 0.025 cent (0.012 cent for iPhone 4 and above) in a visible range of +-5 cent
Yellow position indicator:
Coarse tuning resolution: 0.25 cent (0.012 cent for iPhone 4 and above) in a visible range of +-50 cent
Pluck the string to be tuned about one time per second, while muting the other strings. To handle the fine tuning indicator on this extreme precision level, measure the pitch by very small or no string tension changes. This requires some experience even for professionals but is honoured by an uncomparable sound experience.
Always tune your instrument in 2-3 cycles, as every change of one string affects the other strings. Tune your instrument often to achieve a good tuning stability. Pluck the string with a plectrum to produce an overtone rich sound with the microphone close to the instrument.
