An educational game to learn the location of notes on the fretboard of the ukulele. Ten instruments are available, including guitar (acoustic and electric), bass guitar, mandolin 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)
