healthkit-health-connect

To integrate HealthKit and Health Connect with React Native, configure native modules using Expo config plugins in app.config.ts and build with an Expo dev client to enable cross-platform health data workflows.

Yes, you can read nutrition, exercise, and weight data from both iOS HealthKit and Android Health Connect in React Native. The integration handles permissions and timezone-aware imports to ensure accurate health data retrieval across platforms.

React Native and Expo support background sync on iOS using HealthKit observer queries, while Android Health Connect relies on explicit user-initiated sync to retrieve and update health data reliably across the respective platforms.

Preventing duplicate records during health data imports relies on built-in data deduplication logic. This ensures reliable idempotent updates and prevents duplicate entries when syncing nutrition, exercise, and weight data across both iOS and Android platforms.

Yes, you need an Expo dev client to use HealthKit and Health Connect native modules. Expo-friendly configuration with appropriate config plugins is required to properly configure the native modules for iOS and Android health data workflows.

The best way to unify iOS HealthKit and Android Health Connect permissions in React Native is using a single integration layer that manages cross-platform permission handling, reducing integration complexity and drift between the two distinct health APIs.
