The guitar tuner app used by professional guitar makers, guitar repair shops and musicians around the world.

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!

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

High-quality samples of real instruments are also accessible (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.

The interface:
To make it more intuitive, we give you information about the current pitch in many different ways:

*Cents for the current pitch
*A red/green light indicating the closest pitch
*A note wheel corresponding to the chromatic scale
*A fretboard with the current tuning setting displayed

Standard guitar is set as default but the guitar tuner can be used to tune many different instruments, such as:
*Guitars - Standard, 4-string, 5-string, 7-string, 8-string
, 9-string, 10-string, 11-string, 12-string, and 13-string guitar
*Bass guitars - Standard, 5-string bass and 6-string bass
*Ukuleles - std (Soprano), Pocket, Concert, Tenor, Baritone, Bass, and Contrabass
*Banjo - 4-string, 5-string, 6-string
*Mandolin family - Mandolin (Soprano), Piccolo, Mandola (alto), Octave Mandolin (tenor), Mandocello (Baritone), Mandobass, Irish Bouzouki, Cittern, and Greek Bouzouki
*Violin family - Violin, Viola, Cello (violoncello), Double bass and 5-string Double bass
*Balalaika family - Prima, Piccolo, Secunda, Alto, Tenor, Bass and Contrabass

After you have selected an instrument you choose a specific tuning. The app provides you with over 200 custom tunings.

The tuning options are divided into groups to make them easier to find. For guitar, the categories are:
*General tunings
*Raised tunings
*Lowered tunings
*Dropped tunings
*Double dropped tunings
*Major open tunings
*Minor open tunings (cross-note)
*Modal tunings
*Miscellaneous tunings

If you have certain tunings that you often use, you can save them as favorites. This gives you easy access to them under favorite tunings.

Great tuner app

This is one of the nicer tuning apps available. Very accurate and easy to read. Some of the features should be unlocked without having to pay as I am weary of buying an app will not let you take advantage of at least a few features to judge its overall function. Recently including internal adds really takes away from the uniqueness and clean look of the tuner. Again this takes away from my willingness to purchase the app and the adds are uninteresting anyway. I do not pay attention to internal adds while tuning. Partners are not getting their moneys worth. Overall though, this is a nice looking and accurate tuning. Partners and developers need to be more creative in regard to internal adds and subscriptions.

There are tuners and then there are tuners

It’s interesting even in an app simulation of analogue tuning how close based on criteria presented can make even harmonics level.. I sweeten my tuning and the scale based meter makes for tuning James Taylor sweet easy. This is a fantastic app. If you are looking for tuning down to the cent… it will serve you well. If simple 440 is all you are looking for there are many that will accommodate that but why not just use one that can count 100cents right off? In the end an app like this is where you will land anyway.

That said it’s a simple app.. and can (although it’s very close) replace an analogue harmonic rotary tuner in my opinion. But then again who has the money for a big expense of that… the math is sound. And so is this tuner.

Thank the lord

I have been using a different app and it did not tell me if I needed to tune tighter or you know. I am kind of new to guitar and I broke the low e string string and had to restring. I was terrified that one of the strings was going to hit one of my eyes or my face so I was just putting off tuning. I found this app but I have one suggestion. You should add a way to like tap the string your tunning so it doesn’t think you are doing a different string than what you are.
