"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

Fantastic-buy this!

I don't normally write reviews, but this app is amazing - so much better than my hardware tuner. I've never found it easier to tune my guitars and dulcimer etc and it's much more responsive, accurate and easier to read than my hardware one (which is quite good). I actually bought it as a pitch pipe, but it's become my 'go to' tuner. I write to picture and am recording guitars etc over samples that are very in tune, so it's really important to get the real instruments bang on. Really impressive app.

reasonable app

Like all apps of this type it is distracted by background noise and useless if other instruments are being tuned at the same time. So don't use it if you're in a band onstage.
Otherwise it's pleasant to use, although a bit expensive compared to others. I just tuned my six string acoustic with it and it worked although the needle did fly around a lot once it showed the note.
I've tuned my flute with it and it was useful and the needle held against the note afterwards. I found it useful in getting the pitch right for other flute notes.
With an electric guitar you would have to plug it into an amp as well, probably, to get the volume but I haven't tried that yet as that equipt is packed away.
Ultimately you're limited by the device itself -ipad, iphone etc.
Take it for what it is, something you'd use in the house or other quiet area.

This one actually works properly!!

I downloaded three different ‘Free’ Apps for Guitar Tuners, and none of them worked properly on my phone. All three were also plagued by pop-up ads and scrolling banner ads. So I decided to get a proper App and pay for it.

Well - Cleartune Cromatic Tuner is the business. As a musician for the past 50 years my hearing is dropping off and I needed a tuner to get my guitar perfectly tuned.

On my old iPhone3GS the program runs well, and the mic in the phone picks up the strings of the guitar either through the amplifier and speaker, or (with the case removed to get a slight vibration from the body) direct from the guitar without the amp!

I cannot fault this App - it is great
