Having ditched my scanner recently, I was using the iPhone camera to achieve a similar result, namely, a series of images that I could use for expense reporting.
I was pleasantly surprised to see that Apple’s iOS App of the Week is Readdle’s Scanner Pro. The app typically retails for about $7 (US). However, the app is free this week!
I’ve been using the app for several days, it is great for scanning documents and creating a single PDF from the scanned images.
