"Colortoons" is a nice coloring book app for young children. Consisting of four different themes and now twenty four animals to choose from, kids can either use “paint brush” to paint with their finger much like a traditional coloring book or with the “paint bucket” mode where they can fill in shapes with the tap of a finger. There is also a blank page for kids to draw on free-hand. You are able to save the finished page to your photos, but parents can also disable this if they desire.
My son is not a “keep inside the lines” kind of kid, but at 2.5 years, his fine motor skills are still being developed, and sometimes his fingers don’t do what he wants them to do, so for now he mainly chooses the "paint bucket" setting to color in the animals. I do wish there was an “erase” button because sometimes my son will ask me to remove a mistake if he switches over to "paint brush" mode. When I am not able to, he can get frustrated and lose interest. I do like that both the “paint brush” and “paint bucket” features are available, as well as a blank page for him to draw on.
