ScreenChomp is a very straightforward, attractive, and FREE app with some interesting features. The app provides you with an open canvas to start with. You have the option to choose from three pens, each can be customized to be a different color and thickness. You can then draw with these, switching easily between them. The screen can be swiped down with three or more fingers at any time to allow more space. There is an option to clear the whole screen at one time. Now this all probably seems very basic but the special part is the recording aspect. ScreenChomp allows you to record your drawings in sync with voice recordings. These voice recordings are uploaded to Screenchomp.com where they can be viewed by anyone. There are sharing options given to easily view the screencast as well.
I personally use ScreenChomp in two ways. First, I record myself doing problems, or an explanation of a concept in Physics and use those for homework points. Secondly in many note taking apps you don't have the option to freely draw. In class notes aren't strictly dialect, often there are diagrams and pictures that you need to replicate. I easily switch to ScreenChomp, draw whatever is needed, then take a screenshot and upload it to the notes app.
