They migrated from bare React Native to Expo in 2022 and now use 28 Expo libraries including expo-router, expo-updates, and expo-notifications. A key highlight is their custom TurboModule that integrates Google's MediaPipe Gesture Recognition for real-time fingerspelling AI recognition — built without ejecting from the managed workflow. The team also leverages EAS Build lifecycle hooks for automated E2E testing with Maestro and Playwright. After 10 SDK versions (44 to 54), they maintain 4.9/4.8 star ratings on iOS/Android from a single unified codebase. ## Full article daily.dev links to this article rather than hosting it.
