PhonTuner is an advanced tuner for guitar, violin, piano, and even vocal practice. It is the FIRST precision tuner to detect off-tuned notes in recordings and continuous performance. Enjoy seeing the secrets of popular singers' tonal accuracy and temperament used by top violinists ;-)It can also alerts when your piano needs tuning.

Based on the Mathematical Cochlea of Phonature theory, less than 0.5% tonal frequency difference over a 3 octave range can be clearly seen. The spiral arrangement of an octave enable chords and intervals of melodies to be identified easily. Calibrated Sound Texture pattern in the middle reflects the timbre of sound and reveals fusing of multi-part voices.

PhonTuner indicates the playing note on the Mathematical Cochlea with a big dot and needle for you to see clearly whether it matches the target tone. Singing mode automatically shows singing or whistle in the chromatic scale from C2 to C7; users can define target tones for up to 6 strings from C2 to C5 in Custom mode.
