There are several apps with this name. This review refers to the FREE one by Mind the Kids Ltd.

This app gives kids step-by-step visual and verbal instructions for 12 drawing episodes. Episodes teach how to draw things such as a dog, a princess, and the space shuttle. In the “I am watching” mode, kids can use paper and pencil. In the “I am drawing” mode, the program verbally explains as it draws in red lines for the child to draw over on the iPad or iPhone.  Then the red lines disappear leaving only the child-drawn image behind. There is an option to color and add additional details or background to your drawing. Drawings can be emailed or saved in your photos.

A couple of issues – I think it would be difficult to use this program on anything smaller than an iPad. I also wish there was the option of a blank sheet so that kids could create their own original drawing. It is possible to create your own drawing but… you have to go into an episode and basically ignore the instructions to do your own thing.

All in all, it is somewhat limited but it is also FREE and fun.
