# 10 React Native Performance Tips for Smooth Mobile Apps

Performance is crucial for mobile applications. Here are 10 proven tips to make your React Native apps faster and smoother.

## 1. Use FlatList for Long Lists

Use proper image formats and implement lazy loading. Consider using react-native-fast-image for better performance.

## 3. Avoid Anonymous Functions in Render

Define functions outside of render methods to prevent unnecessary re-renders.

## 4. Use React.memo and useMemo

Memoize expensive components and computations to avoid unnecessary recalculations.

## 5. Enable Hermes

Hermes engine significantly reduces app size and improves startup time.

## Conclusion

Implementing these performance optimizations will result in a noticeably smoother user experience.
