Crayon Kids Painting is a FREE crayon app that features virtual coloring pages. While this app is free, it does have purchases that may be made within the app. The price for the purchases is $1.99, and may be worth it if you are looking for a coloring book for your child. The coloring pages may be more suitable for boys than girls, though there are interesting pages for boys and girls. Some pages that may be beneficial for all include number pages, alphabet pages, dinosaur pages, vehicle pages, animal pages, and fruit pages. There is also an imagine page that is a blank page that children can color anything that they can imagine. Cute outdoorsy kid music plays constantly in the background, which is fun (Music can be turned off). Your child's art is saved in a gallery within the app, itself, and may be viewed by your child in the app.
