Challenge
SDK-only builds lock you to Galaxy hardware
Agnotic approach
We default to Health Connect for portability and use the SDK selectively rather than everywhere.
We integrate Samsung Health across both paths — the Samsung Health SDK for Galaxy devices and Android Health Connect for cross-app data — normalizing steps, heart rate, sleep, and SpO2 into FHIR Observations. Real integrations, not just familiarity.
Trusted by global innovators
























Samsung Health data can reach your app two ways, and the right choice matters. The Samsung Health SDK (Data and Sensor components) gives Galaxy Watch and phone apps direct, richer access on Samsung hardware, while Android Health Connect provides a standardized, cross-app path that avoids per-device coupling. Most clinical builds use Health Connect as the backbone and the SDK only where Samsung-specific signals justify it.
Either path carries partnership, permission, and normalization work. The Samsung Health SDK requires a developer agreement and per-data-type read permissions; Health Connect uses granular per-record permissions and a data-use disclosure. On top of that, Galaxy signals — including SpO2 and body composition — must be normalized into FHIR Observations with correct coding and origin de-duplication before they're clinically usable.
A pipeline that unifies Samsung Health SDK and Health Connect data into one FHIR-native record.

Challenge
Overlapping data between SDK and Health Connect
Agnotic approach
Origin resolution and de-duplication before data reaches the FHIR store.
Challenge
Developer agreement delays access
Agnotic approach
We start the Samsung agreement and permission process early so it doesn't block engineering.
Challenge
Play review rejects health data use
Agnotic approach
Correct data-use declaration, privacy policy, and permission justification prepared before submission.
The exact Samsung and Android surface your integration depends on.
Data and Sensor SDK access to steps, heart rate, sleep, SpO2, and body composition on Galaxy devices.
Standardized cross-app reads via HealthConnectClient where per-device SDK coupling isn't warranted.
Samsung developer agreement, per-data-type SDK permissions, and Health Connect data-use disclosure.
Change-driven reads and background sync so Galaxy data stays current without over-polling.
Vitals, sleep, and SpO2 mapped to FHIR R4 with LOINC codes, UCUM units, and device provenance.
Reconcile overlapping data between the SDK and Health Connect so no metric is double-counted.

Play Store health-data declaration, phased rollout, and sync-health dashboards.
Access methods
The SDK and Health Connect each fit different needs.
| Path | Method | Best for | Notes |
|---|---|---|---|
| Samsung Health SDK | Data / Sensor SDK | Galaxy-specific signals | Developer agreement and per-type permissions. |
| Health Connect | HealthConnectClient | Cross-app portability | Standardized permissions; avoids device lock-in. |
| Live sensors | Sensor SDK | On-wrist capture | Real-time signals during activity. |
| Background sync | Change-driven reads | Ongoing monitoring | Efficient delta reads over full re-pulls. |
We usually anchor on Health Connect and reach for the SDK only where Samsung-specific signals justify it.
