If you play a music instrument - you will need an accurate tuner.
This chromatic tuner uses innovative and most accurate technology for that.
Tuner range is from 50Hz to 650 Hz so you can tune most of the instruments like guitar, ukulele, violin, flute banjo and more. Bass guitars will not fit in this range so you will need a different app if you play bass.

The chromatic tuner displays the notes on a rotating wheel and the sound frequency in the center. It uses your device microphone to pick up the sound and works well even in noisy environments. The tuner is not distracted by harmonics and fallows the tone just like you do using top pitch detection algorithms.
