Dango Pen is an application for drawing thin lines and texts on your iPad screen. Using a virtual pen which has a nib and 3 buttons, you can draw curves, straight lines, arcs and texts. Close adjustments of pen position and direction are possible by drags of buttons. The sizes of buttons are almost same as those of iPhone’s number pad buttons. If you want more close control of the pen position, you can change the ratio of displacements of pen nib and your finger by moving the slider. And you can move the pen position without drawing by a drag or double tap of any other position except the pen.
