"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



  • 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

    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

    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?
  • Great Tuner!

    By lockback
    I use this all the time. It is great! Any chance of making it override the iPhone’s set screen timeout. (Ive got a uke Tibet they can do that.)
  • You took away the lock/unlock?

    By NateSilasRichardson
    I have recommended this app many many times. Tracking is better than most professional hardware tuners. Pitch pipe feature is crucial too! I wish I could still get between notes with it though. Why did the lock/unlock button go away?
  • Terrible

    Unable to pick up frequencies. Want my money back...
  • Proof that something is wrong.

    By KiltedMusician
    I just pulled out my old iPhone 4 with an earlier version of this app on it and it still works. That’s the app I miss. I put my old iPhone 4 and my newer iPhone SE with the latest version of this app on it (as of 6/16/18) side by side and played a tune. The two year old Cleartune app detected the notes and worked properly. The newer phone with the latest version couldn’t even tell a note was being played even if I put the instrument right up to the microphone. It would only make an attempt to detect my playing if I played the highest notes I could. This was with both apps set to the exact same settings. I don’t know what you guys did, but the app is nearly worthless for me now. Most of the time when I try to change the tuning from 440 to something else it ends up popping right back to 440 as soon as I leave the options screen. I don’t understand why this app isn’t working better than it is. Maybe there is some conflict with iPhone SE or something. I have since moved on to other apps, but I really wish this one still worked.
