The crowded document scanner field includes this well-regarded iOS entry costing $4. It lets you instantly scan multi-page documents and send them out when you don't have access to a scanner. Using your iPad, just take a picture of a document, worksheet, photo, graph, map, or anything else. It can reduce paper costs because instructors can scan material, convert it to a PDF, and send it to students. For example, learners can digitally complete worksheets on an iPad or iPod.
