"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 iPhone or using an external mic on your 2nd or 3rd generation iPod Touch.

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, adjustable calibration and more, 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, tablas 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.

Customer Reviews

Great App

Cleartune is very helpful for people on the go. It works perfectly and hits every note. I use it on a regular basis with no problems. Definitely the app for people in need of a tuner. I believe that it does not work well on iPad, as well as older devices. If you have a phone that is quite out of date, I believe your results will vary. If this is not the case, this app will be a BIG help.

hmm not impressed

everyone in the ensemble that I am in highly recommended this app and it was great when I tried it on their phones, so I had high expectations. I recently just tried to download it and accepted the $4.99 fee but before it even started downloading I got a notification telling me that it is unable to download? I tried numerous times and it still won't download. I am thoroughly unimpressed especially since I payed good money for it 😒

Spot on

This app was recommended by multiple musician friends who said they don't even use actual tuners now they have this. Have found it to be brilliant for my Cello.
