Pretty awesome – Draw for GravityFalls Review
It's pretty rad that you can change the opacity of the image behind while you're drawing on the app. They give you like 50 gems a day which is more than enough, and overall it just gives you great close up views of the characters you're trying to draw that you might not be able to easily find otherwise. Pretty cool app so far.
