Samsung Brings Cuff-Calibrated Galaxy Watch Blood Pressure Monitoring to US Users

Samsung began rolling out blood pressure monitoring to Galaxy Watch users in the United States on March 31, letting owners of a Galaxy Watch4 or newer measure and track blood pressure from the wrist through its Samsung Health Monitor app, the company said in a release. The rollout is phased, so the feature will reach users gradually.

The watch does not measure blood pressure directly. According to Samsung, the technology uses a calibrated value to estimate a user's blood pressure, and users must calibrate the watch against an upper-arm blood pressure cuff, sold separately, every 28 days. Once calibrated, compatible watches estimate systolic and diastolic pressure along with heart rate using their internal heart rate sensors, the company said.

Requirements and limits

The feature requires a Galaxy Watch4 or later model running Wear OS 4.0 or higher, paired with a Galaxy phone running Android 12 or higher, according to the release. SamMobile reported that the Health Monitor app must be installed on the connected phone through the Galaxy Store, and that readings can be taken on the watch or through the phone app once the cuff baseline is set.

Samsung's release states that the feature "is not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment or prevention of disease." The company does not describe the blood pressure feature as cleared or authorized by the U.S. Food and Drug Administration.

That contrasts with other Galaxy Watch health tools that Samsung lists in the same release. The company says its sleep apnea feature was authorized by the FDA, and that its electrocardiogram app and irregular heart rhythm notifications have also been cleared by the agency.

What comes next

Samsung said passive monitoring that shows blood pressure trends over time will be added to the Samsung Health app later this year. The company framed the launch around U.S. hypertension rates, citing Centers for Disease Control and Prevention figures that 119.9 million U.S. adults had high blood pressure in 2025.

SamMobile noted that the feature had been long awaited in the U.S. and called it one of the more demanding Samsung Health features, because it cannot be used out of the box without the extra cuff accessory.

The U.S. launch adds blood pressure estimates to a growing set of wrist-worn health metrics on the Galaxy Watch, which Samsung said already include exercise tracking, body composition measurement, heart rate and stress levels.
