Insanely difficult to use, the auto function to find which string you were playing would switch constantly between strings. When doing it manually it would keep telling me that I was playing the wrong string. At one point I wasn't even playing anything and it told me I was playing too high then too low then too high again. Overall this app is kind of tricky, but it got the job done. I seriously hope that this app improves, I see a lot of potential.
