"I have been using this for about a month to tune my fiddle and I'm very pleased with it" .. "I much prefer it to my old hand held tuner because the display is really easy to read (even in dim light) and because it is not affected by surrounding noise."

"Best $4 I've ever spent"

"If you have a guitar and an iPhone. Then this is essential. It is very responsive and easy to use."

"this tuner works beautifully with harpsichord. I normally have to put standard tuners on the jack rail (i.e. inside the instrument), but this tuner is so sensitive, that I can set it on the keyboard. With that, the adjustable A and the historical temperaments, I couldn't be happier." .. "Bye bye, Korg."

"Excellent Application for Musicians and Music Educators"

"This is the answer. It is better than any of my other tuners by a mile" .. "I have used it daily including preparing for professional recordings with a leading Baroque orchestra, and cannot recommend it highly enough to the most serious and demanding musicians."

"Parfait ! Fonctionne très bien."

"The best Tuner ever! I'm selling my Korg now!!"

"Perfekt!"

"Best tuner available on or off iPhone"

"It works great. Totally worth it. Two thumbs up."

"Tuned up my '47 Kay acoustic perfectly"

"Impressive with wind instruments, compares favorably with my Peterseon VSAM"

"I've been using an expensive tuner for years for pipe organs and pianos. I've always had to use it to get me in the ballpark, then adjust by ear. Cleartune put me dead on the first time through! Now, when I need my tuner, is it at home, at the shop, or maybe at my current project? No, it's in my pocket!"
