This is the best app if you start paper folding activity. It's even better than following a step-by-step model with a crap paper in your hands.

On each step, you'll clearly see the line where to fold your e-paper exactly. The app will show you where to put your finger and the direction to slide it.

The great advantage is you don't need to longly stare at a fixed image and try to understand how to fold for going to the next step. All the steps are clearly shown on your screen, each gesture can be seen in a quick glance.

After the last step of folding, take a pen and a color, draw and paint on your folding as shown on the models, or create your own drawings.
