Cool concept! I've been playing guitar for awhile and I find this app really helpful with learning some theory. I think this app would be wayyyyy cooler if it gave some sort odds statistic reading of progress or problem areas the user should work on. Like a diagram that shows percentages of. What was done correctly and what notes on the fretboqrd the user should focus on. Four stars!
Automatically puts a timer on you and it gives you the full fretboard not sharps or flats but you really have to get the notes and the timer helps.
Minor bug fix
