Case Study: Troo cuts app size by 67% with LottieFiles

How Troo Teaches Kids Empathy—and Cut App Size by 67% Using Lottie

Troo, an educational app for children, faced a significant challenge with its large 160MB app size, which risked slow downloads andotional learning. The vendor, LottieFiles, provided a solution using its JSON-based Lottie animation format to replace heavier video files and rasterized animations.

By implementing LottieFiles, Troo achieved a 67% reduction in app size, bringing it down to just 53MB. The solution also resulted in significantly faster load times, animation delivery time from 10 days to just 2-3 days. This allowed Troo to maintain its high-quality, purposeful animations without compromising accessibility or user experience.
