About this app

Guitar Fretboard Trainer for learning guitar notes. Learn guitar notes fast with 2-minute practice. Guided Note Path to find any note anywhere on the guitar fretboard in under 2 seconds.

Ratings and reviews

I've been playing guitar my whole life, but was always chronically stuck at the intermediate level. I decided to get serious about learning and applying theory, and quickly realized I needed to commit the fretboard to memory, at least enough to play along with tracks. I downloaded all the similar apps I could find, and this one emerged as my favorite. It's not perfect. I think the time-gated phase checks are pointless and buggy. Still, it does a good job of presenting the information I need.

FretGenius is the best fretboard trainer app I found or at least the one most in line with what I was looking for. It offers a gamified experience that is addicting and actually makes me practice every day. One thing I would really like is being able to see the entire "skill tree" - the stages I've conquered and those I'm yet to master (Duolingo let's you see this). I guess I like knowing where I stand :) But awesome work!

Solid app. The phase advance time-out feature is annoying, and there should be a way to turn it off and/or reduce the time. I want to use the app but I dont need to wait 8 hours between learning the E string and A string.
