"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.


- Note Wheel Display
- Ultra responsive 25 cent range fine tuning display
- Needle Damping option
- Accuracy ±0.01 semitone (±1 cent)
- Selectable Temperaments
- Selectable Notations (such as Solfège)
- User-defined temperament and notations
- Support for transposing instruments
- Automatic reference note calibration
- Adjustable A4 calibration in 0.1 Hz increment
- Pitch Pipe/Tone generator
- Selectable tone waveform
- Automatic or manual note selection

Note: iPod Touch 3G (2009-2010) requires a compatible external microphone

Customer Reviews

  • IOS 7 fix

    by Ghkkihvfffcghunb

    If it doesn't work on your device with iOS 7, got to settings>privacy>microphone, and turn cleartune microphone on. Works perfectly.

  • Fantastic !

    by AlexanderTudor

    Great find, thanks to Gryphon Palo Alto!

  • Its ok

    by luv2bmommyto5

    It worked fine fir a few months. Then it just froze now it won't let me tune

  • Great app, but...

    by Bookworm3451

    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….

  • Best tuner

    by RegP

    I use to travel with a tuner. Now, I only need my cell phone. ClearTune is the best tuner! It can be calibrated, show the frequency, change the wave form (sine wave is suggested)... ClearTune will keep you in tune! No excuses. Yes, it's worth the money!

  • Best

    by Austin Metzger

    Only wish it wasn't 10MB

  • Git er tuned in

    by Gdrdunn

    I use this at least once a day sometimes twice. I've never had any problems with it it works great!!

  • Really good!


    I use this app all the time to tune my flute and it also helps me with my pitch. It's worth the price

  • Wow

    by Awan96

    So good

  • Love it

    by ljd5678

    It's my go-to tuner - everyone in my string quartet either uses this app on their phone or borrows mine :)

  • Perfect

    by Tyler112989

    Perfect.... Literally perfect.

  • Awesome

    by Dandypony

    This tuner works great. I use it for my trombone and guitar. But a lot of people in my high school band use it to. I love it

  • Works!

    by Ro d

    Tunes without a problem. Easy to use

  • Outstanding Tuner

    by Websquad

    This makes tuning my harpsichord relatively simple. I especially like the pointer that turns green when you are just a few cents away, and the feature that keeps the tool running for the whole tuning session, so you don't have to keep swiping the iPad screen to keep the device from going to sleep. Outstanding!

  • not just best app tuner - best TUNER you can get

    by pwpwpwpw

    This tuner out performs every tuner I've ever used. Better than a stomp box tuner, better than a rack mount tuner, better than a waves plug in tuner. And that's just the "tuning" part. The features are crazy and actually useful. Guitar mode is incredible. This is indispensable for recording sessions, live performance…really anything where being in tune really matters. But the fact that this is an app that you always have in your pocket makes it even better. Can't give enough stars.

  • One of the Best Tuners Ever!!

    by JimEbass

    I have bought many stand alone tuners over the years. This tuner has replaced all those tuners with ease. I may never go back to a traditional tuner again!!

  • Amazing

    by Xophe the boss

    Wow was sitting in the office where I had my guitar delivered and this is just awesome. Super easy, gave me a lot of confidence in tuning (I've snapped a string before so I've been traumatized).

  • Not working

    by dgmarquez

    The app stopped working since last update. It used to work real well.

  • Good

    by Hotboyntl


  • Best tuner I've ever used.

    by Summer Dregs

    And that includes standalone units. And I when I say 'best', I do not mean it is the tuner with the most features (though this one does have tons of features), but simplest and easy to use. Also functions as a pitch pipe, playing any note.

  • Execellent

    by Jesusrocks,993

    Simple, easy-to-use and accurate

  • Fantastic! Really useful :D

    by A High School Band Student

    I find that this tuner is very accurate for my trumpet, and the options make it very easy to switch from tuning my trumpet, to tuning my bass for jazz band. Or my guitar when I'm at home. It has plenty of other options I should know how to use, but I really don't, know... Tons of useful stuff for anyone who does know though!!!

  • Os7-ipad mini-no go

    by smpaudio

    Doesn't appear to work on ipad mini with os7. Really used to love this app.

  • Doesn't work on iPhone 5?

    by Yfbjff

    Ever since I got My new iPhone this app hAsnt worked At all...

  • Stopped working on iPhone 5

    by pickled4589

    Doesn't detect the notes since the new ios 7.0.2 update

  • Does not work on iPhone 5S

    by Alison Barrack

    I deleted and reinstalled and the app does not work on the 5S. It worked fine on the 5.

  • The only iOS Tuber I would ever use.

    by Lzyprson

    This as been my go to app since it's release. I always look for better tuners and haven't found a better one.

  • Disappointing

    by Joseph Walsh

    Beautifully designed program that is impossible to use (at least for guitar). The needle swings wildly from sharp to flat and never settles on "green" long enough to determine if a string is ever in tune. Maddening.

  • A great tuner

    by LSA2013

    I have had no problems with the tuner, and our band director used it for about 3 years until he wanted a more feature-filled app. (I don't blame him considering that he used his phone to tune, record, and act as a metronome.) As a bassist, sometimes it's hard for me to tell when I'm out of tune, especially on the E string. I have always gotten it down to a T when tuning using this. For guitar and bass players (maybe all string instruments?), my other strings tend to ring out when I tune, and that causes the app to spin pretty badly. As long as all my other strings are muted, it works fine. For those rating it very lowly because it's not working: Have you tried using another person's phone/iPod? I watched a friend of mine use this to tune a piano and his trumpet.

  • Does not work in iOS 7

    by Gerwagner55

    Ever since I updated to iOS 7 this app does not work. I really liked it was my primary tuner before that. So I'm very disappointed.

  • Best tuner!!!!

    by Manny Trinidad

    This is the best tuner i've used! Customer service is great also! I used to use the Boss pedal chromatic tuner, excellent also, but now i'll sell it because this tuner is vert precise too. With the iRig, i need nothing more.

  • Love this tuner

    by BigD8234

    I have two tuners that I just bought this one and a 30$ tuner for my guitar. Well after using both I haven't touched my 30$ tuner, I use this for every instrument I own guitar, trumpet, trombone, and tuba and I never plan to look back if you need a tuner this is a great app that I would advise over many store bought tuners. Plus this is equipped with your phone so it's just one less item to carry around with all your band equipment. So all in all I advise this app very precise and usefulo

  • Get this

    by dustinwassoon

    This is the best tuning app I have ever used; I bought many before clear tune. It can be super simple or very complex depending on what you need, full customization of temperament which is a big deal for major musicians

  • Great tuner and price!

    by Endure All

    Very accurate and responsive. Worth paying for.

  • Excellence was expected... and that's what this tuner delivered! It's always with me, the best.

    by Marshal357


  • Hooray!

    by Ejmusician

    Finally, a tuner app that works for classical musicians! So many of the most popular tuner applications are for guitarists, so it was really refreshing to find this one. I love the ability to choose key and notation system and adjust the calibration of the tuning pitch. All though I don't do much historical performance, those who do will appreciate the wide array of different temperaments to choose from. The only thing I wish this app had was a better background noise dampener for use during orchestra warm up.

  • Best tuner app!

    by NCGolfer

    I use a number of electronic guitar tuners and have tried many guitar tuner apps. This one is the best. The app is very easy to use and tuning is very precise. My guitars sound better when I use this tuner. Highly recommended!!

  • Love it

    by Swamproot

    I found this to be pretty handy. I like to turn the tone generator up to about 14k where I can't hear it, but it drives the young whippersnappers crazy.

  • Pretty good

    by Bob Celestvez

    I like it very useful but.....................................……………........................ I like dots. ^^^^^^

  • Awesome

    by C Fantini

    This app is fantastic. I easily tuned my piano with this Tuner. I love it. I highly recommend it.

  • Cleartune

    by Violin 4

    Okay for tuning the open strings on my violin, although it is not able to tune my open E spring. Half of the regular notes are incorrectly tuned, especially third finger and sometimes second finger. Not impressed.

  • A must have for any musician!

    by C. Riggs

    This is without a doubt one of the most useful apps I own. Well worth every penny. It's nothing I would use live, of course, but for practice or just sitting around the house jamming it's perfect. It's precise and works well with any instrument, acoustic or electric. It does seem to have a bit of trouble finding the lower notes like the open E and B string on my basses, but that issue is easily remedied by using harmonic at the twelfth fret of those strings. I highly recommend this app!

  • Worth Every Penny

    by AdamBCE

    I lost my guitar tuner so I got this app until I found it or got a new one. I was very pleasantly surprised with the quality of this tuner and now I'll never go back!

  • Amazing!

    by Werner Bros.

    This app I could go on and on about how good this app is for tuning. I am a violinist and this app helps tune to the finest sound you can make on you instrument. When I want to tune to a certain string I can lock it onto a certain string and and look at the top of the screen to tune it perfectly. This is a great app and is better than all of my handheld tuners combined!

  • Awesome!

    by Alternair

    Just what I wanted. I have several stringed instruments that have various non-guitar tuning. This tuner is perfect.

  • Cleartune

    by Dis my name

    From the gauge, I would guess this is more precise than a standard chromatic tuner, but I haven't tested them side by side. Very convenient for travel. - iPhone 4s running iOS 6.1.3

  • Great app

    by Rmal59

    Accurate. Simple. Fantastic.


    by MacTombo

    Anyone needing a REALLY good tuner needed look no further!! This one has all the functions and options required to tune any instrument with speed and great accuracy. I've been using the app for about 2-years and figured I should this app the kudos it has earned in real world use!!

  • Awesome ^_^

    by Mushroomsuprise43

    Easy to tune!

  • No flip

    by TubadaveBBb

    Great tuner, but still won't flip over when I put the mic up to 'hear' my horn clearly. Have to read it upside down. Used to flip over fine. Now it won't.

  • Fantastic tuner

    by Worknpro

    Best tuner I own.... hands down! Get it!

  • Works great!

    by DeltaForce85

    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.
