Looks neat, is only useful for one string at a time.
The app sort of does what it promises, sort of, the Fretboard is upside down, (low E string is on top).
You cannot customize for the program to only use certain parts of the freborad (vertical learning), which means whenever you decide to use some extra strings you will have to always guess one note per string. Next problem you cannot select individual strings but have to select everything inbetween.
Meh..
