The Challenge

This app teaches reading through the "Science of Reading" method, which requires showing exact mouth shapes (visemes) for each sound. The technical challenge was massive: we needed hundreds of high-quality animations that wouldn't crash the app's performance.

The Solution

I utilized Lottie (JSON) architecture. Instead of using heavy video files, I created vector animations in After Effects and exported them as code. I designed a system of mouth shapes that are anatomically accurate for phonics learning but stylized enough to be friendly for kids. This reduced app size by 90% while maintaining crisp resolution on all devices.
