"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



  • 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.
  • Was good, now trash

    By Kirkkster
    I’ve had this app for years and loved it. The latest update has ruined it. Don’t bother. I will be deleting it and finding something much better.
  • The best iOS tuner for all instruments is back!

    By Laipacang
    Can’t find a better app than Cleartune!!
  • nice app but one recent irritating bug

    By DrGuofc
    i change the “temperment root key” since on the violin c# isnt d flat, but the app has to be restarted to display the new key at the top, which makes me suspect its not set internally in the mapping from frequencies to notes either! this didnt used to be the case.
  • Help

    By Chris D 1983 ATX
    My drummer showed me this app. Works perfectly on his Android. Instant response for tuning my guitar. BUT I just paid 4$ and downloaded it to my iPhone 6 and it is way less responsive...doesn’t even register my low E string. I chose this over the free apps because it worked so well on my drummers Android. What’s going on?? PLEEEEASE fix and update🙏
  • Catastrophic!

    By Obi Wan Kenobi I
    This expensive IOS version with more languages and more beautiful theme is infinity less stable than the Android’s version that I used the last 3 years. It is simply a shame! I use iPad 2017, iPhone ES, Galaxy S8 and Galaxy Tab 10.1 first model. Incredible!!!
