Option A: expo-widgets (community package)
- Pros: Expo-managed, simpler
- Cons: Less mature, limited customization

Option B: react-native-widgetkit
- Pros: Full native access, proven
- Cons: More native code, EAS custom build required

Option C: Native Swift WidgetKit extension
- Pros: Full control, best performance
- Cons: Separate codebase, more maintenance

Recommendation: Start with Option B for balance of control + React Native integration
