RWT Timeline is a wonderful free iPad app (by Read Write Think) for creating timelines. This is all done through an easy drag-n-drop interface and allows users to add linkable images to text text to create a beautiful looking timeline. Also, a user can create their own profile for saving purposes and share via email or print out via a PDF.
I highly recommend checking out RWT Timeline by clicking here!!!
