Overview
- Galaxy Watch 4 and newer in the U.S. began receiving the feature Tuesday, March 31, through a phased update in the Samsung Health Monitor app.
- The watch uses heart-rate sensors to estimate systolic and diastolic values after you set a baseline with a home upper-arm cuff and renew it every 28 days.
- Official use depends on the Samsung Health Monitor app running on a compatible Galaxy phone, limiting support to watches paired with Android 12 or higher.
- Samsung labels the readings a wellness tool that does not diagnose or treat hypertension, with passive trend graphs slated for later in 2026.
- The U.S. launch follows years of regulatory holdups, a backdrop Samsung underscores by citing CDC data that about 119.9 million American adults had high blood pressure in 2025.
