The pro version allows you to access to all the of its features for Video Recording, Multiple Canvases, Academic Backgrounds Bundle, Shapes, Multiple Pictures, and PDF. The Academic Backgrounds bundles include a variety of backgrounds including graph paper, white or black board, ruled papers, photos, maps, etc. I can use a marker as I did in this video or I could have used a pencil. The shapes are the basic shapes but the best thing is the labels that say "First", "Second", "This is on the exam," or even "Make your own" so you can create the little stickies we see in real life.
I would say, download it and play with it. Later on, I plan to try it again and use the multiple canvases and the PDF. I really enjoyed it. Give it a try, see what you think.
