Pretty good - would be 5 stars with temperments
This is a great tuner - better than the half-dozen others I have on the iPhone. Nothing beats a strobe tuner! I have the PolyTune app but its nowhere near accurate enough for me. Id use this tuner exclusively except for one glaring issue: there are no tempered tunings. I know Peterson probably avoids including them because it would cause a massive drop in their pedal tuner sales, but Id pay a premium for their sweetened tunings in this thing (hint, hint)!
