Meh. Get gStrings instead.

It would help to make it play louder. Hard to hear the note. Would also help to make it hold the note. Otherwise ok..

It does what it says. But it's not really a guitar tuner it's more of a tuning key, and it works good for that.

Love this app !!!

works well if u only need 440 standard E tuning. very quiet, hard to hear over an acoustic playing.

In order to tune you will need a good ear to tune rite

Sounds like a banjo...YEE HAWWW

Ok application, but misses the option to hold the note. Hard to strum while pressing the button.
