Ten Great iOS Apps for Toddlers

Fish School

Platforms: iPhone, iPad, iPod touch
Price: $1.99

Fish School, and its iPad-optimized version Fish School HD, uses schools of colorful fish to teach kids basic concepts like letters, numbers, shapes, and colors. As kids get older, there are more advanced activities like spotting which fish is different from the others, or which two fish match each other. There’s also a free play mode, where kids can drag various fish and sea creatures around with their fingers, and experiment with different reactions as the fish bump and move.
