Kitchen Scale description

!!!!!!PLEASE NOTE!!!!!
FOR USE, A ROLLED PAPER SHEET IS REQUIRED!
1. THIS SHOULD BE PUT UNDER THE SMARTPHONE, AS YOU CAN SEE ON THE PICTURE.

The first really working kitchen scale in Google Play Store! Try it!
You do not think it works? Sly algorithms, clever data structures and physics make it possible, which many thought impossible. ;)

To protect the smartphone please do not put heavy, pointed or similar items on the smartphone! (< 500g)

Depending on the paper thickness and the angle the smartphone is placed on the paper, the displayed weight can differ slightly from the actual.
