"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)

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.

Cleartune Reviews


Good, but latest version has problems  Jazzshow  3 star

Calibration by sound feature removed. This is very important to how I use it.


Used to be 5 stars  xsoundgardenx  2 star

The update made this app substantially less good. The tuner used to show a yellow icon that turned green when you found the correct pitch. Not essential but sometimes useful and now it’s gone. The speed and accuracy of the tuning seems to have taken a hit with the new iOS update. The biggest gripe however, is that the screen now dims after a minute or two while I am tuning with students and this is wholly unacceptable. I hope they can make the app like it used to be, but I’m going to look elsewhere.

Best handheld tuner I've found  Joe O'Donnell  5 star

As a replacement for my discontinued Korg tuners, this app has it all and then some. It produces a harmonically rich tone (far more useful for tuning pipe organs, which is what I use if for, than the sine wave some PC programs use) over a very wide range, can be set to various temperaments (including user-programmable ones) and is easy to calibrate. The earlier review complaining about calibration difficulties for organ tuning is just flat wrong. It does require you to calibrate on A if you want to do it audibly; otherwise there is some guess work involved, but that was the case with the Korg AT12 as well. I prefer to tune to a reference tone so I've only made limited use of the meter function - it's not as visually striking as a strobe display but it's perfectly adequate. The recent update to "pitch pipe" mode allowing you to chose notes by tapping the note name rather than spinning the virtual wheel really sealed the deal for me. I've been using Cleartune regularly throughout the holiday tuning season with entirely satisfactory results. On second thought... The recent update, while welcome even if way overdue, has eliminated some very significant features. At least on iPhone the note wheel is way too large and the tap to advance function is gone (pipe organs are often laid out in whole tones so these two features rule out "eyes free" operation). Also, the pitch unlock button is gone and so is the listen to calibrate option. I'd almost given up hope of continuing support for this app, but this update is almost worse than just letting it die. Very disappointing.


Finally it works again !!!  Raffman1987  5 star

I been using this app since the very start I’m so glad it works on iOS 11.keep up the great work!!


Terrible tuner!  Trombonava  1 star

The earlier version was better, towards the end of earlier version and just before the upgrade problems started.. since the recent upgrade, completely unusable even after deleting and reinstalling.


Best tuner on the App Store  HenryC  5 star

So glad this was updated to 64-bit! By far the best tuner I've tried


Awesome  aarseth  5 star

The best microphone tuner I've ever used. I have not tried the iOS 11 update (I'm still using iOS 10) but when I do, I will updated this review.


Not loving the update!  Polydivits  3 star

I rarely pay for apps, but I bought this one a couple of years ago and loved it. I am a music teacher and have referred many students to this app. However, the update has made it frustrating to use for several reasons. I like the smaller size of the old tuning "wheel". This larger size seems to be more "jumpy" and is distracting. It was also very helpful to have the needle stay yellow until the correct pitch was attained (now it just stays green making more difficult to see when that pitch is achieved). I would have rated the app 5 stars with the old version. I will probably look for a new app to use and recommend.


Thank you so much!!!!  Barajazz01  5 star

This is the best tuner app in the App Store!! Thank you so much for making the update!


Thank you for updating!  rhoblidnen  5 star

Having assumed that all was lost and that I’d have to buy a new tuner app, I was ecstatic to see that this one has been updated after all.

Thanks for the update  WeaselTheMr  5 star

Great little tuner


Great Tuner!  DtoC  5 star

Great app! Love this thing and hope it’s updated for iOS 11. ***update: THANK YOU for updating for iOS 11. So happy I can continue to use this.


Hooray! The BEST Tuner Just Got Updated  J A B  5 star

This has always been the best tuner app of them all. Was worried that it would go into app heaven without the necessary update. Fear no more! The BEST is HERE TO STAY!


Great Tuner!  toyboy1980  5 star

Thanks so much for updating to iOS 11 compatibility. This is a daily tool for myself and many musicians all over the world. Cheers!

Excellent tuner!  King Zulu  5 star

Update 2017: This was the app I was most concerned about possibly losing in the switchover to exclusively 64-bit apps for iOS 11. Now Cleartune has been updated to function in iOS 11, and I am greatly relieved. It's (still) an excellent tuner. If you're looking for a tuner, you should buy this one. Previous review: I've had this tuner for quite a while now, and use it to tune multiple and various instruments, from my uke to my piano. It's been very precise and reliable. Highly I recommend it.


The best!  ChristopherMusic  5 star

So freakin happy they updated to 64b for iOS 11!! All the other apps are awful! 7+ years and counting this is still the best tuner for iOS!


Best Pitch pipe app by far  arkofsax  5 star

I’ve used Cleartune for years before iOS 11 since it has by far the best pitch pipe/tuning drone interface of any app I’ve come across. I was upset that after iOS 11 I couldn’t use it anymore, but after the update today I’m more than happy to give it 5 stars!

Best cello tuner I’ve found  Zev Eisenberg  5 star

Others have gimmicks. This works the most like my trusty Korg chromatic tuner, the one I keep forgetting to put batteries in, which is why I went looking for an app in the first place.


Finally updated!!  Mikehendricks  5 star

Didn’t really need a lot of updates...but I used this tuner regularly. Simple to use without a lot of fluff. I was really bummed when it wouldn’t work with iOS 11, but finally (after 4 years) they updated this simple, functional, accurate tuner! Thanks so so much!!!
