An educational game to learn the location of notes on the fretboard of the guitar and other stringed instruments. Eleven instruments are available, including bass (4/5/6 strings), mandolin, ukulele and banjo.

You are presented with a random note on the fretboard, and are offered a variety of choices for the correct answer. Just pick the button corresponding to the correct choice to score a hit!

The new staff training mode also helps you learn the position of notes on the musical staff on the fretboard of your instrument.

As your score gets better and you manage to identify notes faster across the entire fretboard, your working knowledge of the instrument increases!

Game mode provides a fun way to make progress. Work your way through levels of increasing difficulty and compete with your friends!


“ Learning the notes on the fretboard is key to any guitarist's development on the instrument, and [Fretuoso] is a neat way to get that info burned into your brain without having to carry a guitar with you everywhere you go. Pretty cool! ”
-- Bryan Beller (Dethklok, Steve Vai, Mike Keneally)

“ This is one of the best apps I've seen in a while. It's simple, fun and educational. Very useful for guitar players as a lot of [them] tend to play by ear and not care much about knowing the fretboard. ”
-- Rick Musallam (Mike Keneally, Gryphon Labs)

One Request!

Can you fix the game exiting arbitrarily? I’m using the 8 string guitar and very frequently, without any particular patter of usage, the game exits!

Other than that, I love this app! And you’ll love it too!

Partially Fixed

Another update:

App back to being “mostly great”... can’t turn off sounding the notes. Everything else is fixed.

Update: now neither app will open (only goes to gray screen and then hangs until it times out and returns to my desktop).

It feels like it may have something to do with trying to sync with the cloud and then crashes. I did use this app every day. Now I can’t get it to run.

I am on an iPad Pro 11.0 w/256 G memory and LOTS of available storage and latest iOS.


I owned both apps and purchased “all” instruments on both apps ($14). Now, it appears, I only need one of the apps to have on my iPad so after updating today, every time I open either app I have to reset the “restore purchases”... I’m sure this is just a glitch that needs to be corrected. I only rated the app one star so the developer will be sure to see it. When this is corrected I will again rate it 5 stars and remove this review.


Developer Response ,

Thank you for the report. We’ll have a new update out very soon with fixes for this and other issues.

Wrong # of frets for bari uke

Sadly, this program doesn’t well for baritone ukulele. Yes, you can select ukulele for your instrument, and select baritone tuning, but the instrument you see does not have enough frets. The ukulele that you see in the training has 12 frets between the nut and where the neck joins the body. But on a baritone uke, it’s typically the 15th fret where the neck joints the body. You want to train your mind that at the 12th fret the notes are DGBE. But you do NOT want to train your mind to “see” this pattern in the wrong place, in relation to the body of the instrument. Any chance of adding a separate instrument for baritone ukulele? Or perhaps a feature where you could specify the number of frets?
