Overview
- Samsung, which began a phased U.S. release Tuesday, says availability will appear in stages on Galaxy Watch units.
- To take a reading, users must calibrate the watch with a separate upper‑arm cuff and repeat the process every 28 days.
- It supports Galaxy Watch 4 and newer on Wear OS 4 paired with an Android 12 or higher phone and it requires the Samsung Health Monitor app from the Galaxy Store.
- Samsung frames the readings as informational rather than medical care, noting the CDC estimates about 119.9 million U.S. adults had high blood pressure in 2025.
- The capability has been available in South Korea for years and Samsung says passive blood pressure trend tracking is planned for later this year.
