The app is designed to be used with a mouse and a piece of paper, but you can also use it on your mobile device. The first thing you need to do is select a lesson to learn. You can choose from the following categories: Monster, Santa Claus, Pico, Kpop, Anime, Sports, Bird, Flower, Backgrounds, "How to draw", and many others. The next thing is to draw the character you want to learn how to draw. You can use the pen tool to draw a line, brush to paint a color, and the text tool to write a text. You can use the crop option to make your drawing more accurate. Once you're done drawing, you can use the tool to resize your drawing.
