React Native performance tactics: Modern strategies and tools
Blog post from Sentry
In this guest post by Simon Grimm, founder of Galaxies.dev, the focus is on optimizing React Native app performance using modern strategies and tools to meet the high expectations of users in 2025. With the stable release of React Native 0.80+ and the New Architecture, developers have access to powerful tools like Expo Router, Reanimated 4, and Sentry for comprehensive monitoring to enhance app performance. The guide provides detailed strategies to improve various performance aspects such as reducing Time to Interactive (TTI), achieving smooth 60 FPS animations, optimizing list performance, and managing state effectively. It emphasizes the importance of minimizing startup tasks, managing bundle sizes with Expo Atlas, and avoiding JavaScript thread blocking to maintain smooth user experiences. Additionally, the use of profiling tools and Sentry tracing is recommended to identify and address performance bottlenecks, while newer state management libraries like Jotai and Zustand are suggested for finer-grained control. The article concludes by encouraging developers to integrate performance optimization into their development workflow to create React Native apps that deliver native-like experiences and improve user engagement.
