Customer Reviews

Drop capo function gets activated accidentally and mysteriously

I have had many Peterson hardware and software tuners and in general I like them. The "drop capo" function however is absolutely maddening and should be locked out or lockable to "never use this ever". I never need it, never want it, never activated it or any other calibration except normal A440. Nevertheless, about 1/10th of the time when I go to tune an instrument I will discover to my extreme displeasure that I am not tuning to the note shown on the screen but to a LIE based upon the spontaneously-altered drop tuning setting which I absolutely hate and never want and I have no idea how it ever gets activated. The inconvenience of this feature is so great that I am looking for another tuner app.

The best app I've ever purchased.

This is the single most important app I've ever bought. Peterson creates another world of being able to stay in tune and this app is just as accurate as the Stomp Classic or the StroboClip. I'd definitely like to see some sweetened tunings but I've got no qualms with this app at this point, and for 5 bucks it's a steal. I'd have paid 4 times that easy.

Great app

I am a professional flutist and my husband is a professional cellist. This tuner has enough range to accurately tune his lowest note and my highest note on piccolo. The display is large enough to easily see with peripheral vision while reading music. And my flute student actually enjoy working on tuning excercises now. Thanks Peterson!
