Hi

I have heard that performance of prismo very much depends upon the device, the higher the spec of the camera being critical.
What ios device are you using?

However, I'm not having a great deal of success with it, and I wonder if others have had more luck.  Firstly, it seems to have no built in correction for orientation, i.e. you have to know which way up the document is supposed to be.  This is probably OK for pages of books etc, but is difficult for packaging on for instance - products from the freezer.
