I am using this app from around 2 years. This is very cool for scanning documents. U can create pdf of any documents and send it to other person.
The best feature I like about this app is that after scanning the document it enhances the picture quality. It just takes a couple of minutes in scanning complete document and convert it into pdf.
I would say thank you to the creator of this app. This is one of the best app I like in the android.
