"My most indispensable app is my guitar tuner, Cleartune. None of the old visual or analog tuners are as precise. I've even taken it on stage with me!" - Rosanne Cash

"Cleartune and Clockwork are my most used apps." - Ezra Oklan (Nicole Atkins, Norah Jones, Antibalas Afrobeat Orchestra, Matt Beck (Matchbox 20), Chico Hamilton, Arnie Lawrence)

"I've been having trouble with interference on stage with other tuners for the iPhone. Used Cleartune last night before a gig and had no problems with stage noise. Excellent tuner for bass." - Rob Calder (Kanye West, Angus and Julia Stone, The Break and Repair Method, Ghostface Killah)

Used in the making of the new Gorillaz album "The Fall"

Cleartune is a chromatic instrument tuner and pitch pipe that allows you to quickly and accurately tune your instrument using the built-in mic in your device.

Cleartune features a unique "note wheel" interface allowing you to quickly find your pitch, paired with a highly responsive fine-tuning meter for the perfect tune.

With support for custom temperaments, transposition, notations such as solfège, and adjustable calibration, Cleartune packs more power than most pro tuners, yet is simple enough for everyone to use.

Cleartune can tune acoustic or electric guitar, bass, bowed strings, woodwinds, brass, piano, tympani and any other instrument that can sustain a tone.

Most electronic tuners cannot properly tune a violin. With a built in temperament for violin family instruments, Cleartune will have the 5ths singing perfectly.

Bring back the old functionality and look

I want the unlock functionality back in the frequency generator. A useful feature when you are basically working in one temperament but want to tweak one note. The old pull down menu was also better to use and much easier to read, and the smaller pitch wheel was better when you want to quickly flip to a different note. I have the app on three devices and I have now made sure that two of them will not update so that I keep the older version.

Incompatible with IOS11

The best guitar tuner is back, baby! I’ve been waiting for this bad boy to be updated for IOS11 and now that it has, every other guitar tuner app I bought as a replacement has been deleted.

There is no other app as accurate as this, believe me, I went a week without it and was miserable. The other tuners on the market are ridiculous compared to this, my guitar was never perfectly in tune and I ended up relying on old techniques to get me by (which would have been fine had I not been spoilt by the accuracy of Cleartune).

Get all up in it.

Thank you for the update

Cleartune is my favourite - and to be honest one of the best - tuner apps available on iOS. The short time where it was not available after the iOS 11 update really threw a spanner in the works. However the developer has brought it kicking and screaming into the 64-bit era -and it’s come out looking good! The interface is as “clear” as ever, but the change in font is a nice new coat of paint. If you’re new to this app - get it. If you’re an long time user, like me, this update is just what the doctor ordered!
