Scanner Pro, the iOS scanning app from Readdle, has been price dropped all the way down to a very affordable $free from its usual $6.99. My first thought at the price cut was that perhaps Readdle might be dropping Scanner Pro 2 on the app store in the very near future, but as it turns out Scanner Pro has been selected as Apple's first app of the week for 2014, and your chance at a free copy of the app extends through this week only.
I've tried any number of scanning apps, and Scanner Pro is definitely the best I've come across. Scanner Pro's automated edge finder makes for quick and easy scans, images are saved as .pdf, the app connects with Dropbox and Evernote, and I like the "open in..." option for bringing the scan into the app of your choice. Added bonus, Scanner Pro can send your scan along as a fax, for an in app purchase of $0.99. My only quibble would be that the app could embrace iOS 7's aesthetics a bit more, but looks aside, this has to rank as one of the best scanning apps.
