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.

Fix or refund, please?  K.P.G.  1 star

I just purchased this on a recommendation from a fellow violinist. I’m on iOS 12 on my iPhone 5s. The pitch pipe feature does not work at all. I checked settings, restarted my phone, and even removed the app and reloaded it. Nothing. Can you please tell me how to remedy this problem or give me a refund? Follow up: After 3 days of waiting for a response here in the App Store, I decided to try to contact the developer via their website, but all I got after typing in my message and hitting "send" was an "internal server error" message. so I called Apple support, and Apple issued a refund. Thank you Apple for rectifying the issue.

I’ve used this app since it was released and it has never let me down.

Excellent app for band  Greg for God  4 star

I use this app everyday to tune every one. Latest update-the app allows the screen timeout to shut the app down. Why did I loose this functionality?


Update?  byrnzie  1 star

This was my go to tuner for years. I recently updated my iOS and had to update the app. Please tell me how an update can turn a simple tuner that worked flawlessly for me for years into a useless pile a garbage. What happened? The needle display used to move smooth. Now it jumps and jerks. Why on earth would you change this is beyond me. Looking for another tuner I guess. Please change it back. I really used to love this tuner. I make my living as a studio guitarist in Nashville and use this every day for my acoustic instruments. Frustrating.

Iphone x version support please


Jumpy interface  Norcal71  2 star

Paid $3.99 for this app on 2 different iPhones (SE and 7). I like the overall look of the app, but with both phones, and both iOS 11 and the recent iOS 12 update, the tuning needle jumps around almost spastically. It’s very hard to get it in tune and very hard to look at. I’m removing it from both phones and going back to my old free tuner.


Would Like a Refund  Jamz6521  1 star

This tuner is EXTREMELY inaccurate on the low and high octaves of my upright piano to the point where it wouldn’t detect the note I was playing. Please keep in mind I set my 8 Plus into my piano or directly overtop the string so there is no reason that the note should not have been heard. Not AT ALL worth $4.

Have the hardest time even picking up the notes on my guitar. Waste of space


Tuned a 97 year old piano  cavertoo  5 star

This was a very helpful tool to tune my old upright Mallory Piano, especially since I used to tune the piano using one tuning fork. It has never sounded better. Great app.


No longer supports Bluetooth  fritzian  1 star

I used this app for years and now it suddenly won’t send sound over through Bluetooth. Very disappointed.

swami of swank

Update has ruined app  swami of swank  1 star

I've used this app to tune my guitars for years and have recommended it to hundreds of students and fellow musicians. Since the update, it has become useless. It has lost its smooth glide and has become jumpy. I can no longer tune my guitars with confidence. Unless the app is returned to its original functionality I won't be using it anymore. Please fix ASAP!


Great app  Thisisthirtycharacteraters3030  5 star

Love this app. Very straight-forward to use. I can always rely on this app. I installed this other tuner but it was never as accurate as this app.


A great app now totally useless!!  Sheoke  1 star

I can never understand this.. I had this amazing paid app which worked beautifully and now an update (which annoyingly removed the Unlock feature) has ruined it. It is now completely useless - regardless of sensitivity setting and with the phone right next to my violin, the pointer just seems to arbitrarily flick backwards and forwards indicating nothing! Very annoyed that a fully paid-for app is no longer fit for purpose. It should either be fixed or removed from the app store.


Great app really accurate!!  [email protected]😀😋  5 star

Great app it tunes really accurately and is far better than the other free ones! Go ahead, pay for it. It’s worth it!!!


Bring back auto calibration  cheshcat  3 star

Please return the auto calibration function to this app. And the ability to set the manual calibration to less than 1Hz increments.


Back on iOS 11  bryce__bubbles  5 star

Fantastic, simple tuning app. I’m glad it’s updated for iOS 11 as it’s a great app that offers a convenient substitute to a chromatic tuner.


Bring back the old version  Sallyjunping  2 star

The new update is not as good as the old one, needle response is lagging


Very Disappointed  organtuner  1 star

I've used this app for 3 years, very happily, but with the recent update the feature allowing the A4 Calibration to be set with the microphone has been lost. This means that the app is now useless to me. Very unhappy.


Great tuner gone bad.  VinnieV28  1 star

Forget the glowing reviews, in its current incarnation Cleartune is a shade of the app it once was. Previously the most accurate, sensitive and - well, *clear* tuning app going around, none of that praise applies since the iOS 11 update. Firstly I’m not a fan of the zoomed in display, but the real issue is under the hood. It seems not to process notes in real time any more, since the display jerks back and forth like an online game with horrible lag. (I’m on a fully updated iPhone 7 with no other problems so am unsure how anyone could be getting smoother performance). My theory is the developers have made the bare minimum changes to the code to allow 64bit functionality, so it works, but to make it run properly would require a much larger overhaul of the code. Well, get on it developers. That, or consider renaming to Jerkytune. I’ve stopped recommending it to any of my students, but will again if we get a fix - we all want Cleartune back in its rightful place as king of the tuning apps, sadly it’s not even close right now.


Latest update is terrible  SaxxyBen  1 star

Cleartune for iOS11 removed the visual cue of a green light saying you’re in tune and a red telling you that you are out of tune. This seems like a fairly big error and I hope it will get fixed. It’s a shame because the app used to be the best one on the App Store.


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.


After years, still the best  tomatoThaumato  5 star

My favorite tuning multi tool. Great, informative interface with easy to modify tuning system.


Best tuner, on its way back  CZ-1  5 star

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.


Yay, update!!!! And.....  Elanabee  5 star

Seriously, thank you for the update! I don't know what I would do without this tuner. The best out there, period. Just one complaint about the new feel, the arrow pointer is now green all the time, but it used to go yellow when out of tune. It was an added perk and it would be lovely to have that feature back for the next update. Thanks, again!


Update is Great!  drumley1978  5 star

Thanks for getting on the update! Working flawlessly again! You guys rock!


Favourite Tuner App  Hat-trick  5 star

Best app ever  Minions😜xx  5 star

This app the best app ever.Well worth the money.


Amazing  LalaXOox  5 star

This app is so easy to use.i would definitely recommend it😃


Tune up.. Tune in !!!!  J.B.Goode  5 star

Most apps on the iTunes store are just there to take your cash... This app however is one of the best tuners ever... It's far from a toy... No gimmicks here... I've been recording music for 25 years.. I use protools , neve pre amps and valve mics.. And I use this cleartune app.... It's as good as any studio strobe tuner without doubt... It's a rarity on this app store.... If you play music at any level , I recommend downloading this and then perhaps removing your credit card details from the AppStore, tuning your instrument , and play play play ...forget the programming apps that play music for you.. Get this app , and get into life.... Rock on , rap on, folk on , hip hop on , whatever you're into... Tune up... Tune in... Get real !!!!!! Five stars ... Top of the line tuner... Theres nothing else here to compare..and Theres no hardware tuner under 200 euros that's in the ballpark either .. That's for sure.... After that all I can say is the money you save from buying the other crap on here, will contribute to saving for a better instrument....WORK HARD AND BE NICE TO PEOPLE !!!!!... B.Goode

This app is great.I tried a load of the free apps and they were confusing and ultimately useless. I'd never tuned a guitar before I bought this app, is straightforward and accurate.
