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!

I'd rate it one more star if...

I could adjust it so that for standard tuning let's say, if I wanted the big E string tuned 12 cents under 440 and the next string 10 cents under, etc etc, the tuner would remember that. Is this even possible I don't know, but it would be cool. Minor grip for an awesome tuner

Fabulous! Get it now.

This is a great and very flexible and useful tuner. Great graphics, handy and intuitive, this is a great app.
Note to developers: it needs a Buzz Feiten tuning and I agree it would be very cool if the user could program anything they want.

What? Adds?

I bought this app a while ago, and have enjoyed using it to tune my guitars. But now that it updated to a “new” version suddenly I have adds at the bottom of the screen, and they want me to pay more to have a “premium” version? What a scam! I’m deleting this app immediately.
