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)


- Train your ear while improving your working knowledge of the instrument.
- Learn the position of notes on the musical staff; say goodbye to tabs!
- Ten different beautiful, realistic-looking instruments! Includes 4 guitars, 3 basses, mandolin, ukulele and banjo.
- Focus your training on particular parts of the fretboard: any range of frets, any subset of the strings.
- Many common tunings are built in, but custom tunings can also be created.
- Visualize your progress on the fretboard; statistics are kept for every fret.
- Smart Learning Engine: the app automatically focuses on sections of the fretboard where you are weaker.
- Integration with Game Center, Twitter and Facebook: compete with your friends and share your progress!
- Left-handed mode is available.

Guitar enthusiasts ,

Fretuoso is fun!

Fretuoso is a great tool for learning the notes of the staff and the location of the notes on the fingerboard. You can play it when you’re away from your guitar which is great on vacation or on a break at work.
Thank you for a great product!

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.

Paid for the full version, kinda regretting it.

Generally speaking the app has a very dated Web 2.0 looking interface and it’s lacking in all but the most basic features that other software offers. Want to practice with only naturals? Sorry! Want to specify *any* options in ‘game’ mode? Again, nope. Want to increase the difficulty and skip the first 20 or so levels of basic 5 fret quizzing? Sorry! I was hoping for a ‘note hunter’ mode where you could be given a note and have to track them all down. This app is super basic, practice mode and a progressive difficulty quiz mode, that’s it. I recommend looking a Fretonomy instead.
