Joyful Color Book is a simple coloring app that comes in many languages. Children choose from Halloween pictures or Fairytale pictures. There are in-app purchases for transportation color sheets, animals color sheets, instruments, Christmas, and numbers. To purchase all coloring books it is $3.99. To purchase each coloring book individually the cost is .99 cents. We enjoyed the calming music that is plays as you color the picture. We also enjoyed how the app helps you to color close to the lines without going over. This is helpful and encouraging to children who are meticulous and can get frustrated with their work when they make a "mistake". However, with that said you can still color "outside" the lines, the app just supports you if you are "trying" to stay within them. This app is without advertisement and is easy to use. We trialed this app with a 5 year old boy with Down Syndrome as well as a 5 year old typically developing boy. Both enjoyed the app and were proud of their different creations. Their attention lasted for one picture each. We would suggest this app as a centers activity in an Early Childhood setting. Or, as a reward for a child who enjoys coloring but has trouble grasping a crayon or marker.
