Outstanding app - highly configurable – GuitarNotes - Master Fretboard Review

This is exactly what I was looking for. My fretboard mastery has skyrocketed over the past several weeks, more so than the last 6 months. Mix up the strings and the positions strategically, and watch your knowledge and comfort level explode. I’m doing 4-5 three minute sessions a day and am blown away by my progress.
