I was re-stringing my guitar and my tuner was at the studio so I had no reference to tune from. Low and behold I discovered this nifty little app and it saved the day! This is perfect for guitarists, like myself who are obsessed with keeping in tune all the time. I dont see what the big deal is with the fact that there are no octaves. If your a decent musician finding an octave shouldnt be that hard. Anyway I downloaded this app and it got my guitar in tune!!! Which is awesome. Buy this app!
