Comparison
Health Connect vs Samsung Health: differences and when to use which in 2026
Not competitors. They work together. But it matters to understand who does what so you don't disable the wrong one.
Published May 21, 2026
The confusion is understandable. You have a Galaxy Watch, turn on the phone and see two apps: Samsung Health and Health Connect. Both talk about steps, HR, sleep. They look like they do the same thing. Natural question: do we really need both? Can we uninstall the one we don't use?
Short answer: no, they do different things, and on Samsung phones with Galaxy Watch you need both. Long answer: read on.
Samsung Health: the manufacturer's app
Samsung Health is the official companion app for Galaxy Watch (and accessorily for other Samsung devices). Its job:
- Receive data from the Watch via Bluetooth.
- Display it in dashboards, charts, achievements, guided programs.
- Sync it with the Samsung Health cloud (if you have a Samsung Account and the option is on).
- Since mid-2024, automatically write to Health Connect for the requested data types.
Samsung Health is proprietary, focused on the Samsung user experience, and includes consumer features like food tracking, guided fitness programs, social dashboard (challenges with friends). Its data model is fully its own (internal format, not publicly documented).
Health Connect: the Android exchange layer
Health Connect is an API and an app distributed by Google, designed as a neutral layer where all Android health apps write and read. It doesn't have a rich user dashboard — it's almost just a control panel showing you:
- Which apps have permission to read each data type (steps, HR, sleep, etc.).
- Which apps have permission to write.
- History of who read what when.
- Button to revoke permissions individually.
The Health Connect data model is publicly documented (developer.android.com/health-connect), structured, and each type is an explicit class. It's Google Fit 2.0, fully on-device.
How they work together
On your Galaxy Watch, the actual data flow is:
- Watch sensors → BLE → Samsung Health (main app).
- Samsung Health stores internally + (if enabled) writes to Health Connect the allowed data types.
- Health Connect keeps a neutral copy of data and exposes the API to anyone with permission.
- Third-party apps (FitMesh Sync, Strava, MyFitnessPal, sleep coaching apps, etc.) read via Health Connect.
Practical differences, one by one
| Aspect | Samsung Health | Health Connect |
|---|---|---|
| Primary function | User app: visualize, workouts, coaching | Permissions layer between health apps |
| Rich dashboard | Yes (steps, sleep, food, challenges, ECG, etc.) | No (permissions only) |
| Cloud sync | Yes (Samsung Cloud, opt-in via Samsung Account) | No (strictly on-device) |
| Proprietary data types | Yes (e.g. Body Composition, guided workouts) | No, only standard schemas |
| Manual export | CSV via app, slow process | No user export (third-party apps do it) |
| Updated by | Samsung | Google (via Play Store) |
When to use which
- Want to see your sleep with detailed charts or follow a Samsung workout program? → Samsung Health.
- Want a third-party app (e.g. MyFitnessPal, dietitian app, coaching app) to read your data? → You need Health Connect with granted permissions.
- Worried Samsung sends your data to the cloud? → In Samsung Health → Settings → Privacy disable 'Sync with Samsung Cloud'. Data stays local and keeps flowing to Health Connect.
- Want to see who's reading your data? → Open Health Connect → App accessibility: see the full list with timestamps.
- Want to uninstall one? → On Galaxy phones you can't uninstall Samsung Health (preinstalled) but you can disable it (you'll lose Watch sync). Health Connect is preinstalled on Android 14+ and can be disabled without breaking Samsung Health.
What if the phone isn't Samsung?
Still works. Samsung Health is free on the Play Store also for Pixel, OnePlus, Xiaomi. The Galaxy Watch pairs via Galaxy Wearable (also multi-brand) and Samsung Health takes over to read data. Health Connect sync works the same way.
Frequently asked questions
Can I use Health Connect without Samsung Health?+
On a Galaxy Watch no — Samsung Health is the official bridge between Watch and phone. Without it the Watch won't sync. On other wearables (Pixel Watch, Mi Band, Garmin, Polar, etc.) you can use the respective companion app + Health Connect and ignore Samsung Health entirely.
Do data pass through Samsung cloud even if I only use Health Connect?+
Depends on your settings. If you disabled sync with Samsung Account in Samsung Health, data stays local on the phone then is copied to Health Connect (also local). If cloud sync is enabled, data is first in the Samsung cloud then copied locally — even though Health Connect only sees the local copy.
When does Health Connect not receive Samsung Health data?+
Three typical cases. One: Samsung Health → Settings → Health Connect not authorized (default situation on many devices until 2024). Two: only some data types authorized. Three: an old Samsung Health version (< ~6.20) doesn't have HC sync. Update and re-authorize.
