Splash of Color is a cute free coloring app for the iPhone and iPad. It has some neat little features that makes it pretty fun. I like that they have a lot of different textures that you can color in addition to their color wheel. I also like the “stickers” that you can add to your drawing. There are plenty of “pages” to color. The only downside is that it takes more than one tap to switch colors versus offering a range of colors on a sidebar which makes it less user friendly for very young children.
Recommended for children 3 and up.
