There are times when I need to de-tune my guitar down to Q and I had no tuner handy. Thanks to Gibson for their iPhone App that includes tuner and metronome.
Partial description:

- A Standard Mode Tuner that allows you to tune each string to a sample tone
- An accurate Metronome with multiple time signatures, visual and audio options, and a set-your-own tempo tap pad

Did I forget to mention that it’s free?
Still, there’s no instruction to downtune to Q.
