"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.

Ratings and Reviews
Best tuner, on its way back
I am a classical violinist and have used this app every day for about 3 years. I was very pleased that it works again after the iOS update, but I note two new issues: 1) The frequency “read” seems somewhat less stable than before, with transient errors up to a 5th, apparently unrelated to input volume or ambient noise. 2) I also miss the continuous mode for the frequency generator - a survivable omission, but occasionally useful. Similarly, it would be nice if the wheel could be made to rotate in analog fashion to show out of tune inputs, rather than locking on a particular note, with deviations shown only on the meter above the wheel.
Despite these issues, this is still by far the best tuner app I have seen.
Thank you for the update!
Thank You! Thank You! Thank You!!! . I’ve been a professional musician since 1980 and this is BY FAR the best and most accurate guitar tuner I’ve ever used. I was devastated when IOS 11 came out and the tuner wasn’t working. Thanks for the quick update. The temperament function really makes it worth it, too. Ever since I read an article in an article in Disc Makers Blog, I’ve used it regularly. Below is a brief section from that article:
James Taylor, in order to accommodate the vagaries of acoustic guitars, tunes his strings flatter than normal. Here is his guide:
High E string -3 cents
B string -6 cents
G string -4 cents
D string -8 cents
A string -10 cents
Low E string -12 cents
This tuning method is also great for using a capo.
Now, your mileage may vary. Your guitar is different than Taylor’s guitar. Your action may be higher. Maybe you play harder. Maybe you don’t use capos. Try it out and adjust your tuning as need be.
Anyway, thanks again! This tuner is the best of any I’ve found in the App Store, and (if you’re a serious musician) is worth more than the price you are charging. Have a wonderful day! -DJG. nyc
Why did you remove features?
This has been my go-to tuner for years. As a music teacher, I was able to use the app on two different devices side-by-side to demonstrate what it sounds like when two pitches go in and out of tune with each other (using the tone generator). The “unlocking” feature that removes the pitch grid is essential to the success of this lesson because the students could see the wheel move farther and farther away from the pitch and compare it with the sound waves they hear (as the waves get faster, the pitches go out of tune with one another). They LOVED it and it was an extremely effective lesson. This feature has been removed, unfortunately, and now I need to find an alternative app. Very disappointed.
