A lot or a little?
Parents need to know that Colors -- Therapy Coloring Book is an art book for iOS and Android devices. It offers a solid array of drawings kids can color, add patterns and other effects to, and save or share. Figuring out how to color items isn't difficult. Kids get instructions and can also refer to an FAQ if they find anything confusing. The app is free to download, but ads pop up fairly frequently when you access drawings or want to unlock some of the color palettes and other extra items. Users can also pay $7.99 to remove them. Otherwise, there's no inappropriate content to be found.
