Im a professional musician, and thought this app would help me out if I forgot my real tuner. It was utterly useless while I was sitting in a perfectly quiet room. The note detector kept dancing all over different notes, and the fine resolution bar jumped back and forth between +/- 20 cents like a mofo. Im good with technology, and I know my instrument is good quality and should be easy enough to get in tune. This app is garbage.
