Kidjo is an excellent free mobile (iOS/Android) app for finding educational videos, songs, cartoons, and more for kids ages 2-7. Best of all, Kidjo is COPPA compliant so you know all digital content is safe for kids to use. Also, parents can set time limits through Kidjo's parental control and even store videos off-line to view w/out an internet connection. Finally, new videos are added every week.
I highly recommend checking out Kidjo by clicking here!!!
