Scanner Pro for iOS

Thanks to Nate Boateng, I found out that the well-regarded Scanner Pro is on sale for $2 right now (down from $7). This app will let you scan paper documents and receipts with your iPhone or iPad camera, then send those scans off to places like Evernote and Dropbox. It even uses an algorithm to clean up the images and make them more readable, which lends itself very well to Evernote's OCR functionality.

Scanner Pro is perfect for anyone trying to achieve a paperless lifestyle. Go get it.
