n-Track Tuner Pro

Tune your guitar, bass or other instrument with n-Track Tuner Pro. Just put your device next to your instrument and play each string, the tuner will automatically recognize the note you're playing and tell you wether you need to lower (green bar) or increase (red bar) the string's pitch.
The spectrum analyzer provides a visual feedback of the notes played by the instrument and shows a small arrow to highlight the harmonic whose pitch the tuner is tracking.

For those who prefer to manually tune their instrument the 'Diapason' view lets you play a reference tone, 'A' (440 hz) or any other note that you can select dragging the frequency slider.Advanced features
