"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



  • Why did you remove features?

    By Drummin
    This has been my go-to tuner for years. As a music teacher, I was able to use the app on two different devices side-by-side to demonstrate what it sounds like when two pitches go in and out of tune with each other (using the tone generator). The “unlocking” feature that removes the pitch grid is essential to the success of this lesson because the students could see the wheel move farther and farther away from the pitch and compare it with the sound waves they hear (as the waves get faster, the pitches go out of tune with one another). They LOVED it and it was an extremely effective lesson. This feature has been removed, unfortunately, and now I need to find an alternative app. Very disappointed.
  • Used to be perfect.

    I miss the lock button feature. I liked being able to turn the lock off on the pitch pipe and generate tones at any frequency.
  • Not very good, waste of money, useless

    By Katdan
    1. Does not do a good job tuning my santoor that is like a hammered dulcimer and has 100 strings, is not accurate and the needles bounces all over the place. I use the tuner in guitar toolkit which works much better. 2. Custom temperaments doesn't really work, my tonic note is D and want to use custom tuning from that, but not working, it is not clear how they are determining the few frequency of the root note. 3. I email them about item #2 months ago, no reply. Pretty much useless app.
  • Latest update stopped working!

    By Clark Battle
    Ive used this tuner for years. It was great! Now the dial just sits there. Guess I’ll have to use my ears.
  • Clear tune keeps us honest

    By Marcel Pappillion
    This tuner to me seems like the old school Conn Strobe tuners. I got dialed after reading Roseanne Cash’s article in ? (National Enquirer?) no... I forget. “A musician will spend on average 2-3 lifetimes playing, then they do something else.” Satananda
  • Don’t like the update

    By toshitazawa
    What happened to my favorite tuner? The update now makes the meter so herky jerky compared to the more realistic movement, it is not only more difficult to use, it is annoying.
  • Max 480 now?

    By KiltedMusician
    This is a great app, no question. There were two specific reasons I got it. One was the ability to customize temperament (bagpipe temperament is different than any preloaded setting) and the other was the ability to set A440hz standard to higher than A480hz. On a warm day the band goes over 480. There seems to be some difficulty getting the hz to change though. Often it is ignored and goes right back to its previous setting. It also seems to need to be set one hert at a time to change it. Otherwise it ignores bigger changes. Odd bug. Great app though. I’ve told everyone else in the band about it and some of them have bought it.
  • Used it for years, but it stopped working completely

    It doesn't work at all anymore
  • too good to be true, but it is true

    By Minton Miller
    I have always had trouble keeping my mandolin in tune. The string sets never or seldom ever sounded right to me my guitar, mandolin, dobro and banjo have never sounded so good! I triedClear tune in noisy rooms where other tuners failed, and it worked perfectly! In less than a week, I have scrapped my various clip on tuners in favor of this extremely accurate Cleartune tuner. It is worth the money at several times the price!!!
  • No more analog reading

    By W0lvie77
    I’m very familiar with this tuner, It used to be my best,I used it for 5 years but it’s is not as great as it once was, the note doesn’t get picked up as quick as before. It doesn’t really scan quickly. I hate this digital look. Good news is, it’s very precise. So please, give us back the analog feel to it.
