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

*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)

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.

This is amazing

I was having trouble with tuning my guitar for a while. I think the clip on I had was just bad. So I downloaded this app I was able to tune my guitar in three minutes tops. If you want to tune your guitar and don’t want to mess it up I highly recommend this app.

Do not upgrade to Premium!

I used this product for a day or two, then paid $5.99 to upgrade so I could do more with it including turning ON my iPad microphone which works just fine. It isn't listed as wanting access to the mic. ALSO I wanted to turn the display so I could see the tuner in lanscape mode (easier to see for me) can't do that either. I see NO difference between downloading the Free version vs the Premium. I can ONLY use the tuner in portrait mode and only for guitar. Something is seriously wrong with the overall programming. My iPad works just fine.
