ABCmouse

ABCmouse delivers the most comprehensive early learning curriculum for ages 2–8, combining reading, math, science, art, and music into a structured 10-level progression. With over 10,000 activities — puzzles, books, songs, and animations — it's even more robust than the typical library app. The reward system issues tickets and in-app currency for completing lessons, which 35 million children have used to customize virtual classrooms. It's also adopted by thousands of schools, and its learning path is 30% more detailed than the average early learning app.
