Scanner Pro is one of the most highly rated scanning apps in the App Store and is designed to turn the iPhone or the iPad into a portable scanner for documents, receipts, notes, photos, and more. The app removes shadows, sharpens scans, and corrects perspective in order to make scans as "readable as possible."
It also utilizes edge detection in order to create fast, accurate scans, and it stores scans as PDF files that can be uploaded to Dropbox, Google Drive, Evernote, or emailed/printed.
Scanner Pro transforms your iPhone and iPad into portable scanners. It allows you to scan receipts, whiteboards, paper notes, or any multipage document.While Scanner Pro has been priced as low as $1.99 during sales, it typically costs $6.99 to download. For the next week, it will be available from the App Store at no cost. [Direct Link]
Scanned documents can be emailed and printed, uploaded to Dropbox, Google Drive and Evernote, or simply saved on the iPhone/iPad.
