Samsung has started rolling out blood pressure monitoring to Galaxy Watch 4 and later models in the United States. Samsung categorizes this feature as a wellness tool rather than a medical device.
The rollout is happening gradually, as explained in a Samsung blog post published today. To use blood pressure monitoring, the watch must be running WatchOS 4.0 or later, and the paired smartphone must be running Android OS 12 or later.
Arm Cuff Calibration For Galaxy Watch Blood Pressure Monitoring
The feature does not work on its own. Users need to own a traditional upper-arm blood pressure cuff to calibrate the watch's sensors. Samsung explains that calibration is needed during initial setup and then every 28 days. The first calibration must be done through the Samsung Health Monitor app.
The watch uses readings from the cuff to establish a baseline for its internal sensors. Without a compatible cuff and completed calibration, blood pressure tracking on the watch is not possible, regardless of the model or software version.
Passive Monitoring Plans And Supported Galaxy Watch Models
Once calibrated, you can take blood pressure readings directly from the watch. To do this:
- Go to the Home screen, swipe left to the Blood Pressure widget, and tap Measure.
- Follow the on-screen instructions and tap OK.
- Sit still and avoid talking while the watch measures your blood pressure, then tap Done.
Samsung has announced plans to release a passive blood pressure monitoring tool later this year. The device is designed to display blood pressure trends over time without requiring manual readings. No specific release date has been provided by Samsung.
The compatible models include the Galaxy Watch 4 and all subsequent Galaxy Watch models running WatchOS 4.0 or later. Samsung has not specified which upper-arm cuff models can be calibrated with the device or whether third-party cuffs are supported alongside Samsung's own hardware.
