I came to know about this application by the recommendation of my friends, i am a property consultant, so I have to do documentation that relates to property, this helped me to go easy with scanning the documents in emergency needs, its a user friendly application, and I loved the adjustment option, you can scan any documents or paper just by taking pictures.
Just have to click the picture of the document and you can adjust it according to your comfort level.
I prefer you to go with the CamScanner, this is very good application.
