Cool idea! but not practical

kind of a fun finger game, but really not applicable to the real guitar. A great idea! Worked smoothly on my phone, but it really is nothing at all like a guitar. Not to say that the app can be improved in any way, I just think the only way to get better at finger agility on the guitar is to do it on the guitar. Also kind of hard to hold and do at the same time.
