n-Track Software has released n-Track Tuner for iPhone, iPad and iPod, a new free App that features the power of n-Track Studio's spectrum analyzer, level meter and guitar/bass tuner.

Features:

• Automatic Tuner: just play any note on your instrument and the tuner will display a bar indicating whether the note is too flat or too sharp. Adjust the note's tuning to bring the tune bar to the center and you're done.
• Spectrum Analyzer: shows the detailed frequency content of the audio acquired from the device's built-in mic, and shows a cursor highlighting the frequency harmonic that the tuner is tracking.
• Diapason: for those who whish to manually tune against an audible reference. A frequency slider lets you manually select the frequency of the note played, play with it to see up to which frequencies you can hear.
