Duolingo ABC

Duolingo ABC transforms early reading instruction with the same addictive gamification that propelled its parent language app to over 500 million downloads — and like Khan Academy Kids, it remains completely free. Each phonics-based lesson incorporates instant feedback and reward animations, compelling children ages 3-8 to progress through 700+ activities. This approach matches Homer in effectiveness for early decoding but surpasses it by delivering the content without any subscription fees, making high-quality literacy instruction accessible to every family.
