It's the most powerful tool you've ever had in your pants! You know ... for tuning. That said, this is one of those nuggets on the App store you cannot afford to miss if you value being in tune and you take your smartphone with you when you go places. Yes to both? Then it's a no-brainer! - Tune all strings at once! Just strum your guitar, and see the pitch of all strings instantly. - Guitar/bass mode - Drop-tunings - 1:1 port of the award-winning PolyTune pedal (Guitar Player, Guitar World, Premier Guitar, MIPA, NAMM Best in Show 2010, etc.) - Based one the world’s best selling pedal tuner used by countless pros such as Steve Vai, John Petrucci, Steve Morse, Orianthi and many more! PolyTune is the world's first polyphonic tuner that will have future guitarists wondering how we ever got by without it. The magic lies in a never before seen approach to tuning aimed at speed, accuracy and ease of use, which allows you to get in tune fast, and back to doing what you love: playing. The PolyTune iPhone app is a 1:1 port of the award-winning PolyTune pedal tuner, and PolyTune for iPhone delivers exactly the same features and tuning technology as the pedal version. The pedal version is the fastest way to tune on-stage, whereas the iPhone app is the fastest and most convenient way to tune off-stage. Specifications: - Reference pitch from 435Hz to 445Hz - Drop tuning from E-flat to B - 0.5 cent accuracy - 2 chromatic tuning modes: Needle and Stream - MonoPoly recognizes whether one or several strings are played at once



  • Worth every penny.

    This tuner is every bit as accurate as the real PolyTune. Polyphonic function works perfectly. The best thing about this app is that they don’t nickel and dime you to death with in app purchases, unlike Peterson. 5 stars!

    Not working on my IPhone? The stings are not being heard?
  • Works good with iRig. Adapter on the iPad

    Works good with iRig. Adapter on the iPad With electric guitars especially in noisy environments line in is a must.
  • No capo functions

    By eltalon
    I'd like to give this five stars, but I capo a lot of times… If it's so easy to add "de-tuned" guitar tuning options, why can't they go UP the neck from the regular E tuning, and do the F, F#, G, G#, A... etc. Seems pretty easy to add these features… Look, I know how to tune open and then capo after that, but a lot of times a capo messes with the tuning, usually makes One or two strings go sharp, so I like to tune right through the capo. Any flamenco guitarist would appreciate a capo function...
  • Worth the buy!

    Gotta be honest, this app is so worth it. I think it might be the most spendy non-subscription app I've purchased, and I only regret waiting so long to do so. The pedal version of TC PolyTune2 is amazing, and the app does everything a $150 (MSRP) pedal does for 1/30th the price. One major advantage of the pedal version is how it isolates the instrument, and is not affected by ambient sounds, and that's perfect for noisy, musical environments, where a quick tune or de-tune is needed. I haven't experimented with it yet, but I'll bet I could use the headset jack with an adapter to get line-in on my iPhone or iPad--or use an effects send from a mixer. Anyway, great to use, easy to understand, scorchingly fast and accurate. SPEND THE MONEY.

    In my oppinion the new update ruined the app. It used to be my favorite tuner. Now it's harder to read and more difficult to use.
  • 7 year long update

    By yankeeabe
    They updated this App after 7 years, and it never even needed one. Kudos.
  • 2.0.0 Update - Thanks

    By OAR FAN #1
    I've been waiting literally years for this app to be revamped. I'm glad it finally happened. Love the update, thanks TC Electronics!
  • Best tuner app available. Thanks for the update!

    By Johnnysaw
    I've been waiting for this update for a while. Thanks!
  • Reliable tuner, needs updating!

    By austinfuture
    Just had a message pop up after opening this app that it may slow down my iPhone since the developer is due to update it. Please see this and do so! I've been using this PolyTune app for close to three years. It's my main go to other than my actual PolyTune mini pedal. I want to be able to keep using it as it's the most expensive app I've ever purchased.
