Samsung Galaxy Watch blood pressure monitoring is now available in the U.S.

Samsung has enabled blood pressure monitoring on Galaxy Watch devices for users in the United States. The feature is accessible through the Samsung Health Monitor app and works on Galaxy Watch 4 and newer models. This has been available in South Korea since 2021 and in a handful of other countries since then, so the U.S. rollout is years in the making, delayed largely by the regulatory process with the FDA.

Blood pressure is one of the most clinically relevant health metrics a person can track. Hypertension affects roughly 119 million adults in the United States, according to the CDC, and a large portion of them either do not monitor regularly or rely on infrequent clinical readings. Getting that data onto a wrist-worn device that people already wear daily changes the practical reality of how often someone can check their numbers.

How the feature actually works

Samsung's blood pressure monitoring uses a method called pulse wave analysis combined with the watch's optical heart rate sensor. It does not use an inflatable cuff. Instead, it measures the shape and timing of your pulse to estimate systolic and diastolic pressure. Because it works differently from a traditional cuff-based monitor, it requires an initial calibration step using a standard cuff before the watch readings are considered reliable.

Users need to recalibrate every four weeks using a conventional blood pressure cuff. That is a real limitation and something Samsung is upfront about. The watch readings are meant to track trends over time rather than replace a clinical measurement. If someone's readings are consistently creeping upward over two weeks, that pattern is useful information even if any single reading has a margin of error.

What took so long for the U.S. release

The FDA classifies blood pressure monitoring as a medical device function, which means it requires regulatory clearance before a company can offer it to consumers in the United States. Samsung had to submit clinical validation data demonstrating that its cuffless measurements were accurate enough to be used for health monitoring purposes. That process took years, and it required Samsung to conduct studies comparing its watch readings against validated clinical devices across a range of patients.

Apple has faced the same regulatory barrier for blood pressure on the Apple Watch. Despite years of reported development work, Apple has not yet launched a blood pressure feature in the U.S. Samsung getting there first is a concrete competitive advantage, at least until Apple clears its own FDA pathway. Fitbit, now owned by Google, has also not released a blood pressure monitoring feature for U.S. users.

Which Galaxy Watch models support it

The blood pressure feature works on Galaxy Watch 4, Galaxy Watch 5, Galaxy Watch 6, and Galaxy Watch 7. Older models like the Galaxy Watch 3 are not supported despite having optical sensors, likely because Samsung is limiting the feature to hardware that meets its internal accuracy thresholds. Users need a Samsung account, the Samsung Health Monitor app installed on a paired Galaxy smartphone running Android 7.0 or later, and they must be 22 years of age or older.

There is no iPhone compatibility. The Samsung Health Monitor app does not run on iOS, which means Galaxy Watch users who switched to an iPhone cannot access the feature. That is a known limitation of Samsung's wearable ecosystem and one that has not changed with this rollout.

What this means for the wearables market

Health monitoring has become the primary reason many people buy smartwatches. ECG detection, blood oxygen readings, and sleep tracking have all been standard features for a few years now. Blood pressure was the notable gap. Closing that gap matters because it shifts the Galaxy Watch from a fitness tracker with health features into something that is genuinely useful for people managing chronic conditions.

For Samsung, the timing is useful. Galaxy Watch 7 launched in mid-2024, and Galaxy Watch 8 is expected in the second half of 2025. Having blood pressure monitoring active in the U.S. gives Samsung a concrete health story to tell at the next device launch. The feature also increases the stickiness of the Samsung Health ecosystem since blood pressure history stored in Samsung Health is one more reason a user stays within Samsung's device family at upgrade time.
