"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



  • The Best

    By Alcraine
    I’ve used this app since it was released and it has never let me down.
  • Excellent app for band

    By Greg for God
    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?

    By byrnzie
    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.
  • Please

    Iphone x version support please
  • Jumpy interface

    By Norcal71
    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

    By Jamz6521
    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.
  • Terrible

    By l am that guy
    Have the hardest time even picking up the notes on my guitar. Waste of space
  • Tuned a 97 year old piano

    By cavertoo
    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

    By fritzian
    I used this app for years and now it suddenly won’t send sound over through Bluetooth. Very disappointed.
  • Update for iPhoneX?

    By LuddyBassman
    Good tuner, but needs an update for iPhoneX. Any timeframe for this?
