I love this app. Unbelievable how well you can draw diagrams. Changes are directly transported to the server. I looked for this kind of tool so long.

I am an engineering student, and it is excellent for my notes where I need diagrams, figures (it transforms “scribbles“ into shapes like circles, straight lines, etc.), it has different brushes with different lines, it allows you to play with the thickness, etc.

It is one of best tools. I use it frequently for work and university lectures. I actually bought the iPad just to run this application - haven't seen anything better on the market.
