Tap the screen to switch between draw and sense modes. To draw, switch to draw mode, upon which you feel a long vibration. Now drag your finger across screen. The drawing is black on orange. The device vibrates while you draw, with a slight change when you cross an existing line. To sense what you have drawn, tap the screen to switch to sense mode. You feel a short vibration. Now simply move your finger on the screen. The device vibrates when there is black color below your finger. To clear the screen, rotate your phone from portrait to landscape or vice versa.

Narangi in Hindi means "orange" which is the color of the background on which you draw. Na rangi, on the other hand, means "without color". Since this is a monochrome drawing app, that seemed like an appropriate name.
