After years of anticipation, Samsung Galaxy Watch users across the United States are finally gaining access to the blood pressure monitoring feature. This rollout commenced in a staged manner starting on March 31, bringing a significant health tracking capability to American users.

Regulatory Hurdles Cleared for U.S. Launch

The delay in the U.S. launch was primarily due to the need for clearance from the Food and Drug Administration (FDA). Samsung initially announced this capability back in 2020, when it received approval from South Korea’s Ministry of Food and Drug Safety.

Device Compatibility and Calibration Requirements

While the feature debuted on the now-discontinued Galaxy Watch Active 2, current users of the Galaxy Watch 4 series (released in 2021) and subsequent models are eligible for the update. Importantly, this functionality does not operate entirely independently.

Samsung's system requires users to first establish baseline readings using a traditional blood pressure cuff. This calibration process must then be repeated approximately once a month to maintain accuracy.

In the interim between calibrations, the Galaxy Watch utilizes its standard heart rate sensor array to estimate fluctuations in blood pressure.

Galaxy Watch vs. Apple Watch Health Tracking

This measurement method differs from Apple's approach, which was introduced in 2025. While an Apple Watch may alert users to potential signs of high blood pressure, the Samsung Galaxy Watch provides actual estimates for both diastolic and systolic readings.

However, the convenience factor favors Apple, as the Galaxy Watch necessitates regular calibration checks. Conversely, the concrete estimates offered by Samsung may prove more beneficial for individuals managing hypertension, a demographic for whom Apple's alerts are not specifically designed.

Expanding Samsung's Cardiovascular Toolkit

The addition of blood pressure estimation enhances the Galaxy Watch's existing suite of heart health features. Since 2020, select models and regions have supported the electrocardiogram (ECG) mode.

Furthermore, detecting potential signs of atrial fibrillation using the standard heart rate sensor is a common capability across many modern wearable devices from various manufacturers.
