We don't tend to associate words like "scanning," "PDFs" and "documents" with fun. After playing with Handy Scanner, though... well, we still don't. Sorry. That headline was a lie. Scanning documents is, however, a breeze with this freemium app. Breezy enough that you won't want to go Office Space on your scanner, and that's fun.
Handy Scanner is very straightforward. Take a picture of a document that you want scanned. The app will pinpoint the corners of the document, perform a little perspective correction, and then you'll be presented with a few filter options. The most notable filter is "Print Ready" which will render the photo in black-and-white and ready for printing.
