Kalulu is more than just a game — it’s an educational adventure grounded in scientific research that helps children learn to read through a decoding-based method.

Each lesson follows a structured sequence based on linguistic data drawn from children's literature. Learners start with vowels and gradually move on to more complex sounds.

🎯 Goal: Make learning to read fun and effective
🌟 Science-Based: Developed using research in education and neuroscience
👶 Target Audience: Primarily children, but useful for anyone wanting to learn to read
🔎 Published Research: Several articles have been published on Kalulu's design and reading results, read here:
