FeaturesScanner Pro recognizes documents, receipts, photos, notes and more once the camera focuses on it. You will see a blue box around it to indicate that the piece of paper with the press of a button is scanned. The app removes shadows, and corrects perspective in order to make scans readable.
You can find in Scanner Pro a few in-app purchases, but you can work perfectly with the app without using one of these in-app purchases.
