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.


- 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

Very poor pitch discrimination

A tuner should respond to small changes in pitch. The PolyTune app doesn't. Glad I didn't pay full price for this. Still trying to recover my 99 cents. (Hint: If you want a refund because an app doesn't work as advertised, report that you made the purchase in error. If you report that there's a problem with the app, iTunes store bounces you to the vendor's support site and prevents you from registering any further issues with Apple.)

Tuning? TC got you covered

This is just a great app by TC, definitely it works for everything not only guitar or bass, is prety good when you tried almost with any instrument (flute, sax even vocals). I will like to know if this will work with IK iRig device... Love the update and the option to change coorx to blu/yellow

Poly tuner

Do NOT buy this app it is a pain in the butt to use nothing about it works well it dose not tell the difference between playing one string or all of them as well as it should i have compared it to my other tuners and what this app says is in tune all my other tuners show it is higher than being correctly tuned it does not pick up sound very well and the slightest bit of backround noise will be picked up i would suggest getting an actual tuner
