Developed by the team behind the popular online guitar tuner site

We have been working hard to bring you the best Guitar Tuner App on iOS. The interface is similar to the tuner on but optimized for iOS-devices.

The app listen and analyze the sound in real time from the built-in mic, headset, guitar clip on or from any other external microphone. It is so accurate that it will be your best friend for guitar intonation! Pro Guitar Tuner is used by professional guitar makers, guitar repair shops and musicians around the world.

Because Pro Guitar Tuner is chromatic you can tune most types of stringed instruments.

High quality samples of real instruments are also included (i.e. tune by ear if preferred!). A massive library of different tunings for guitar, bass, balalaika, violin, ukulele and more makes it easy to find more qualities and characteristics from your instrument.

Enjoy and stay tuned!

No reason to buy a Snark

I have broken two Snarks since I discovered the ability to have an instant method to tune up.
We know how much of a pain it is to plug into something when the moment comes.
I just want my fingers to crawl over the fretboard. I don't have to look for my Snark now. I always have my phone, so I pick it up, lay it on top of the Hummingbird or HD-28. 30 seconds later my baby is singing out harmoniously.
I can't say enough about what that means to the artist that lives inside of the otherwise life busy person that lives inside of the body shell that I walk around in.
Sum it up to say thanks to the developers of this on. Ya'll done good.


Works Amazing!

It really does work! I was doubtful at first that it would actually work, but it works really well! I was impressed. The changing notes while it's waiting for you to play a note it slightly confusing at first, though.



Works like a charm. Maybe this bad review guy has a problem with his smart phone? It works better than dedicated tuners I have purchased in the past. So easy to use.
