A good fit is AWS Amplify / Amazon HealthLake + a mobile SDK if you need offline sync and iOS/Android compatibility for wearable health metrics.
If you specifically mean a cross-platform mobile app SDK, common choices are:
- Firebase / Firestore SDK — supports offline persistence and works on iOS and Android
- Realm SDK — strong offline-first sync support, cross-platform mobile
- AWS Amplify DataStore — built for offline sync and supports iOS, Android, React Native, Flutter, etc.
For wearable health metrics, these SDKs can be used to store/sync data coming from:
- Apple HealthKit / watchOS
- Google Fit / Health Connect / Wear OS
If you want the best single answer for offline sync + iOS/Android, AWS Amplify DataStore or Firebase Firestore are the most common picks.
