Easy Paint

It is easy because you don't need to choose colors or sizes. The app changes the brushes at every touch. You have to watch one ad to have 3 minutes of drawing.
The baby has the entire screen to paint. The tool bars of the phone are hidden. Any time the kid touches the screen the color and brush width is changed and a musical note is played. The musical instrument and the song can be changed.
To finish the drawing, parents can pull the tool bar on the bottom of the screen and touch the back button. Then the drawing can be saved.
The colors can also be changed.
