Penultimate is a featured app because with it you can create and share whiteboards. The pen tool allows for drawing freehand in several colors and three thickness. Photos can be imported, resized, repositioned, and marked up. The scissors tool allows drawings to be selected and either moved or deleted. Undo and redo buttons allow for multiple changes during creation. Finished pages and notebooks can be merged, saved as PDF files, saved to Evernote, or shared as Penultimate files with other users. Penultimate is a free app that only works on an iPad.
