It's like an amperage meter or something... doesn't work well at all to tune the guitar... Little needle bounces all around, weird note names flash back and forth, with nothing to do much with the string played. Back to the drawing board boys, imho. I hope it was free. Sorry.

I want a refund

This app is a complete fraud. It does not help you to tune your guitar. How do I get a refund? I gave it one star because the "Rate it" app makes you put a star on the review. RATED ZERO (0)

Doesn't work at all, waste of a $1

Crashes and doesn't hear the instrument. No settings. I'm wondering if I just paid $1 to install malware.
