Big-time PDF applications like Adobe Acrobat are great, but for many folks, splurging on them seems like hauling a pricey, seven-course banquet to a picnic at the beach. Many people are better off spending less to get only what they need. (You wouldn’t want to get sand in the caviar.)
And if a free app comes with a few great free features plus in-app purchases to get more, all the better. That’s PDF Editor PDF Book Reader in a nutshell. And one of its free features — PDF Scanner for iMessage — is especially cool.
