Samsung has begun to implement blood pressure monitoring to Galaxy Watch 4 and later models in the United States. Samsung classifies this feature as a wellness tool rather than a medical device.
The launch is taking place 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.
Galaxy Watch Blood Pressure Cuff Calibration
The feature does not work on its own. Users need to own a traditional upper arm blood pressure cuff to calibrate the watch sensors. Samsung explains that calibration is needed during initial setup and every 28 days thereafter. The first calibration must be done through the Samsung Health Monitor app.
The watch uses readings from the bracelet to establish a baseline for its internal sensors. Without a compatible bracelet and full calibration, it is not possible to track blood pressure on the watch, regardless of model or software version.
Passive monitoring plans and compatible 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 launch a passive blood pressure monitoring tool later this year. The device is designed to show blood pressure trends over time without the need for manual readings. Samsung has not provided a specific release date.
Supported models include the Galaxy Watch 4 and all subsequent Galaxy Watch models running WatchOS 4.0 or later. Samsung has not specified which models of upper arm bracelets can be calibrated with the device or whether third-party bracelets are compatible with Samsung’s own hardware.
