Mobile Development

React Native Patterns

• Expo managed workflow preferred
• React Navigation for routing
• AsyncStorage for local persistence
• Platform.select for iOS/Android differences

Performance

• FlatList for long lists (not ScrollView)
• Image caching (expo-image or fast-image)
• Avoid inline styles in render
• Minimize bridge calls

Native Features

• react-native-track-player for audio
• expo-notifications for push
• expo-file-system for file operations
• expo-secure-store for sensitive data

App Store Readiness

• Proper app icons (all sizes)
• Splash screen configuration
• Privacy manifest (iOS)
• Required permissions justification
• Test on real devices before submission
