Best free PDF scanner app

[iPhone 5_to_GS4]

I have a DocScan on my iphone and it was just perfect. Good clean scanning and no brand stamping on the lower corner. And it was free.
I have tried about 5 on Note 3 and none of them seem to work as well as the iphone app.

Does anyone use document scanner regularly?
