"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" Follow us on Facebook at ----------------------------------- • Featured in Electronic Musician, Matchbox Mag, Making Music Mag, Premiere Guitar, MacWorld, Apple Staff Picks, Worship Leader Mag, Acoustic Guitar • Spotted in use backstage by The Black Keys, C.W. Stone King (, Grammy Nominee Sones de México ( ----------------------------------- 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. Features: - 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



  • Used to be perfect

    By hiwag49
    I am a classical violinist and violist as well as a teacher. I also play other instruments for a hobby. This app used to be perfect whether I was tuning a note that had to be perfect, tuning my violin knowing it had to be exactly in tune with other tuners, or tuning my banjo or tenor guitar. Now the wheel flails aimlessly no matter what the needle damping setting is. I’m not recommending this to my students any longer and probably won’t use it any more myself until I see another update and give it a test drive.
  • Older version better

    By kricket504
    The older version (before the September 2017 update) ran a lot smoother. The needle didn't have such a harsh waver action. Is there a way to download the older version again?!
  • Not working on IOS 11

    By JbenthNYC
    I’ve been using this app for a few years and it worked great. But now I’ve been getting “app needs to be updated” messages from my phone for many months. Not sure why they dropped the ball on this popular app. Now, with 11 on my phone, it doesn’t work at all despite the supposed update. (It has access to mic) ... will need to get a different tuner app.
  • Serious loss of functionality with this update

    By Xoviolin
    Please restore full functionality to the signal generator function! Why did full frequency range disappear in this version? I use that every day to dial in reference frequencies. It was great, now its worthless. And the half second lag on the on off button for pitch generator is so annoying!!! Giving one star as of this update v2.2. will return to a great rating when I can generayr any frequency again.
  • Sliding tuning gone: much less useful

    By the_waltzer
    I'm a singer and have used this app for 7 years. I like the ability to adjust the temperament, change octaves, and use both the tuning and pitch modes. Like another reviewer noted, the sliding tuning scale is now gone, which sadly makes app useless my purpose, since I work with choirs and often need to work in the cracks between standard pitches. If you just need to tune a single, loud instrument, it'll probably work fine.
  • Not thrilled with the update

    By Glbmstar17
    I’m a musician who likes to put a tuner up on the stand and play through an entire piece of music to check for any intonation issues. With the newest update, if I’m not actively touching the screen, it dims and locks on me, which I find annoying. The only way around this is to change the settings on the phone to never lock, which I don’t want to do, so I’ve essentially stopped using this tuner and gone back to my old Korg. As I’ve used and loved this app for years, this is a huge disappointment. Other than this issue (which is a huge one for me), the tuner is accurate and useful, but the pros aren’t enough to overcome the cons for me at this rate.
  • Great tuner - ruined by the update!

    By Joe O'Donnell
    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.
  • The update made it less stable

    By duh harro312
    I find it harder to tune with this new update. I liked how before the arrow stayed yellow until you were in tune and it became green. I don’t like how zoomed in it looks now. The wheel doesn’t move fluently like it used to. It’s overall not good anymore.
  • Excellent tuner, just two small things I would fix

    By Nathan#11
    This tuner is excellent. For the money, you won’t find a better tuner for your iPhone. It’s easy to use, accurate and customizable. It had a pitch pipe setting so you can easily listen to any reference tone you like. That being said, I noticed two small differences from the older version versus the new iOS 11 version: 1. The green needle used to turn green when you were +/- 5 cents from the center of the pitch. Now it’s perpetually green. Please change it back to how it was. 2. The pitch pipe used to have a lock setting so that you could set it to any pitch and listen to what it sounds like in or out of tune. Please bring that lock setting back so the pitch pipe works exactly as it did before. No big deal, just hoping the developers see this review and make those changes if they feel the need to. I hope they do.
  • So glad this was updated...

    By Alex from the North
    I didn’t value Cleartune until I couldn’t use it for awhile. I tried several alternatives and I learned that some are better than others. Somehow I’m able to tune both more quickly and accurately.
