Skitch is a featured app because it has a simple interface that allows for sketching on whiteboards, photos, webpages, and maps. Whiteboard annotation drawing tools include a freehand pencil, arrows, shapes, and text boxes. Individual annotations can be moved, resized, and deleted. Maps are accessed directly inside the app and include boundaries and names for each county. Drawings can be exported to the camera roll and synced with an Evernote account. Sketch is a free app that works on an iPhone, iPod touch, and iPad.
