Wow! And I dont write reviews.... But,

I really wanted Omnigraffel for the function ability and just could not bring myself to pay the fee. I use it on the desktop and can make magic with it.... So I went searching for an iPad app that gives me the ability to create a diagram with text and free hand pictures. This is the one. Until now I had been using audio notes, penultimate and a couple of others. Done looking.
