Scanbot, the popular PDF and QR code scanner, has received an update bringing the app to version 3.1.1 and introducing a few new features for basic and Pro users alike.
When scanning a document, a brand new black and white filter can be used to achieve more accurate scans that preserve more structure from images. When reading a PDF file, you can now swipe to go back.
Finally, the app now bundles a 'Get Started' document to help get users up to speed and a few nice-to-haves for Pro users listed after the break.
