The radial OnScreen Menu

As usual I started with the classic buttons for an app. But from the fact that You have to hold the smartphone with one hand and the chisel-rep with the other, my fingers began to become tired.
On thinking what would be the most natural positioning of buttons for the typical holding position of a smartphone it soon became clear that moving the thumb over the screen is a radial movement. So I adapted the Idea of the Pie-Menu ( Pie-Menu on Wikipedia) to a touchscreen surface. Fancy isn't it?
