"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, but...

This app hasn't been working since I got an iPhone 5C (hence an OS upgrade). I tried everything to get it to work, and finally tonight I found their Facebook page and the solution. Why isn't it posted here?? It's a great app, but this info should be posted clearly in the app description here.
Next, the developers should work on a port of the old application called "Intonation Trainer"--a great program that was marketed incorrectly that I found indispensable for teaching students how to tune chords and intervals and to make an intonation map when evaluating new horns. I think these guys could make a really elegant version.
If they edit this page, I will happily add that final star….

Great with an iRig

This tuner works great with the phones built in mic on an acoustic guitar. It works ok on an unplugged electric if you hold it really close to the strings, but for electric it really shines when connected through an iRig(I'm sure other similar adapters work fine too).

I've used this on iPhone 4, iPad 2, and iPhone 5. My main use is still on my old iPhone 4 which I keep around as a beater for just this type of use. I'm guessing this would have worked fine on my 3G while I still had it if I hadn't killed its usefulness by installing iOS 4 on it which slowed it to a crawl.

Works great!

This app is a life saver. It is extremely accurate. We have several tuners lying around but I always reach for my phone. I have tuned every guitar I own from acoustics to bass guitars and never had a problem with a note registering.

I plug the guitar into my phone when tuning. I have used the iPhone built in mic before and it worked fine as well. Those complaining about certain notes or frequencies not picking up can blame the mic not the app. If you are having an issue like this, try moving the soundhole itself closer to the mic.
