This "Pro" version doesn't add any watermark to the generated PDF files. All features are the same in free version and Pro version.

Scan documents, customize the layout, save as a PDF file.

Perfect for receipt scanning, once scanned you can crop the image, optimize the contrast.

Trick: during cropping, when an anchor is selected (with magnified view), slide your finger anywhere on the picture (not on the magnify) to move the anchor with precision.
