This is a great new app for the iPad. It costs only 99 cents. It alllows you to use a stylus to take notes, linked audio recordings, PDF annotations, Advanced Word-Processing, inserting photos or drawings, and more.
This is an easy app to use to provide videos for your students. I used this to prepare a video of a teaching model for my A&P students.
