"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

Needs to be Updated!!!!

This is by far the best tuning app that I’ve ever used. I don’t usually purchase apps or let alone review apps, but this is one that I made sure to purchase and comment on because it’s just so great. There so many features that can be adjusted to whatever music you trying to play or tune to; the versatility of this app is astounding. The only problem I have with this is the updates, or the lack thereof. I just updated my phone to iOS 11 and I cannot use this app with the new update. Hopefully the developers update this app soon so my money will not go to waste.


Both this and very sadly Stagepass are not updated anymore for compabillity anymore. This app made me buy an Iphone. Now I have to keep a couple of phones from updating to new ios! Stagepass has been taken off the app store. This is a serious loss! Please save the Stagepass app. It is totally unique and there is nothing like it. The effort is also like no other app out there. Again I am saving a couple of phones just for these 2 apps please don't loose them. Update them! I will pay for the update!! Stagepass is a gem!!

Please Update!

This wonderful tuner is the only one in the App Store that really works and that I know I can trust. It's really accurate and easy to read and understand. Today I just found out by looking in my settings that this app is not compatible with the IOS 11 update. I was really disappointed by that because I need this app to tune my instrument, and it's hard to find a really good tuner. Could you update its compatibility please?
