Draw Curves, a good android drawing app for all age. It’s basically designed to gain the knowledge of different structure of curves with easy to use painting on canvas. It supports all colors and some gradient. Any one can fun for random generated curves with random color. Most of the curve size is design on according to your finger drag length. So if you drag big then your curve size is bigger and if you drag small then your curve size is small.

Huge new curves add new version. I hope you really enjoy more now.
4 Step Undo/Redo option, First button for single curve and Second button for multiple curves
