ToneTune 1.2

New for Version 1.2: Revised interface is easier to use, smoother, and faster!

ToneTune is a multiple tuning fork that lets you set up and tune stringed instruments by ear.

Over 100 different tunings are included, covering common guitar tunings and alternates, and quite a few instrument tunings from around the world!

ToneTune helps you tune the strings on your instrument to the correct pitch by ear without searching through hard-to-find books or the web. Simply select your instrument and tuning, and tap the graphic to get the right pitch for each string. Even better, it can play all the notes in sequence, as many times as you like.

You can also pick individual pitches to play over 10 octaves.

The best sound reproduction will be achieved by connecting your iPhone or iPod touch to quality headphones or a sound system. Be careful that the volume is set low enough so as to not damage your ears or your equipment! (please note that neither your iPhone, iPod touch, headphones nor sound system can fully reproduce the entire range of these pitches)
