Great idea, but......
I like the app and would really use and promote it, except for one very, very annoying problem.
Unless I move my finger very slowly all I get are dashed lines. The faster I more my finger the more dashed/broken the line becomes. There are a number of art drawing apps that do the same thing as this app (and more) without the issue of dashed lines. Definitely getting rid of the app until that problem is fixed.
