Sound Touch is intentionally simple for developing brains, but won't be boring for your toddler or preschooler. As they press images on the screen (animals, music, transportation), a correlating sound and image pops up—the roar of a lion, the ringing of a phone, the rushing of a train on tracks, etc. Each item has five different pictures or sounds attached to it, keeping kids engaged longer than you'd expect. Being entertained while they are (unknowingly) schooled? Sounds smart to us.
