I absolutely love this app of all the coloring apps Ive tried there is only one other that even compares. So why only four stars? Well, my only complaint is that there isnt more pics. There is an alternate "book" but at $1.99 apiece things could become pricey. Another nice feature would be an actual color picker. The current setup is click on the dropper and you find yourself seeing a vast array of colors, the problem is that the squares are so tiny its hard to know what color you touched and even harder to find the exact same square later in your artwork. My other fave color app has a color picker whereupon you touch it then touch a colored area in your pick and that exact color will become your current color. Just a thought.
