Tune your guitar, bass or other instrument with n-Track Tuner. Just put your iPhone, iPod Touch or iPad 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 that the tuner has recognized and tracking its pitch. You can tap on the spectrum analyzer to switch visualization mode.

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.

Note: 2nd and 3rd generation iPod Touch require an external mic connected.
