I absolutely recommend this APP
still, there is room for improvement:
e.g. using the ipad built-in camera as scanner results in strange problems regarding edges of the picture and also in colors and contrast.
I would wish that if I use the camera as scanner, to just get the picture in full color and resolution as I define and then be able to save as pdf.
Also some scanners still arent found on the network.
