Yes, the Samsung Galaxy Watch 8 has blood pressure monitoring, but with important requirements and limitations.
Requirements
- Samsung phone required — Feature unavailable with other Android phones
- Regular calibration — Must use traditional BP cuff every 28 days
- Samsung Health Monitor app — Required on paired Samsung phone
How It Works
The watch uses optical sensors for pulse wave analysis, estimating blood pressure from pulse patterns. This method requires calibration against a real cuff for baseline accuracy.
Calibration Process
- Take reading with arm cuff
- Immediately take watch reading
- Watch calibrates to match cuff
- Repeat monthly for accuracy
Accuracy Expectations
This is not medical-grade monitoring. Best for trend tracking, not clinical decisions.
Factors affecting accuracy:
- Calibration recency
- Watch position on wrist
- Arm position during reading
- Movement and temperature
- Individual variations
Regulatory Status
Approved in some regions (South Korea, parts of Europe). Not FDA-cleared in the US specifically for blood pressure monitoring.
Non-Samsung Phones
Blood pressure monitoring is locked to Samsung devices. Pixel, OnePlus, and other Android users cannot access this feature. For reliable readings, use a dedicated blood pressure monitor.
Bottom Line
Useful for casual trend tracking if you own a Samsung phone. Not a replacement for medical-grade monitoring or regular doctor visits.
