Samsung Galaxy Watch now tracks blood pressure in the US. Discover how it works, which models support it, the big caveat, and our full watch review
Samsung Galaxy Watch blood pressure monitoring has finally arrived in the United States, and it marks a major turning point for wrist-based health tracking. After years of availability in dozens of other countries, US Galaxy Watch users can now measure their blood pressure right from their wrist. But there is one major caveat you need to know about before you get too excited.
If you own a Samsung Galaxy Watch and have been waiting for this feature, the wait is over. Starting March 31, 2026, Samsung began rolling out blood pressure monitoring to compatible Galaxy Watch models in the US through the Samsung Health Monitor App. This article covers everything: how the feature works, which watches support it, what the big catch is, a full review of the Galaxy Watch lineup, and answers to the most common questions.
Samsung Galaxy Watch Blood Pressure Monitoring in the US: What You Need to Know
Select Galaxy Watch users in the US can now monitor and track their blood pressure right from their wrist using the Samsung Health Monitor App. This is a feature that has existed in over 70 countries for years, and US users have finally gotten access to it.
Samsung first introduced blood pressure monitoring on the Galaxy Watch Active 2 back in 2020, but US users were left waiting due to regulatory barriers. The long delay frustrated millions of Galaxy Watch owners who had purchased their devices specifically hoping to use this feature.
"Nearly half of all US adults — about 119.9 million people — suffer from high blood pressure. Wrist-based monitoring puts real health data where it matters most: on your body, every day."
The blood pressure monitoring feature is not intended to prevent or diagnose high blood pressure, but it gives users greater insight into their health and wellness, enabling them to make more informed decisions.
How Does Blood Pressure Monitoring Work on Galaxy Watch?
Samsung's system estimates blood pressure indirectly using pulse wave analysis, whereas traditional cuff-based monitors measure it directly by detecting pressure in your arteries. The watch uses its built-in optical sensors to analyze the way your pulse travels through your blood vessels and converts this into a blood pressure estimate.
The feature works by using the watch's internal sensors to measure systolic and diastolic pressure alongside heart rate. You can see your numbers directly on your wrist or review them later in the Samsung Health Monitor App on your phone.
Step-by-Step: How to Set It Up
- Download the Samsung Health Monitor App from the Galaxy Store after connecting your compatible watch to your Galaxy phone.
- Enable blood pressure monitoring inside the app to begin the setup process.
- Use a traditional upper-arm blood pressure cuff (sold separately) to perform the initial calibration on your Galaxy Watch.
- After calibration, your watch can take blood pressure readings anytime using its optical sensors.
- Repeat the calibration with the arm cuff every 28 days to maintain reading accuracy.
- View systolic and diastolic readings on your watch face or inside the Health Monitor App.
You must calibrate your Galaxy Watch using a separate upper-arm blood pressure cuff every 28 days. Without this recalibration, the readings become unreliable. The arm cuff is sold separately and is not included with any Galaxy Watch model. This requirement is built into the technology itself: the watch estimates blood pressure based on a baseline set by the medical-grade cuff, and that baseline drifts over time.
This approach lets Samsung classify the feature as a wellness tool rather than a medical device, helping it avoid FDA clearance requirements that had previously stalled its US release.
Compatible Galaxy Watch Models for Blood Pressure Monitoring
Blood pressure monitoring is live in the USA for the Galaxy Watch 4 and later models. Wear OS 4.0 and Android 12 or higher are required on the watch and the connected smartphone.
Important: Blood pressure monitoring requires a Samsung Galaxy phone to function. This is an FDA compliance requirement specific to the US market, not a design choice, but it is still a real limitation for users pairing their watch with a non-Samsung Android phone or an iPhone.
Full Samsung Galaxy Watch Lineup: Complete Review
Galaxy Watch 8
The Galaxy Watch 8 is the standard pick in the current lineup. It features a round-cornered square case design that Samsung has refined over several generations, packing BioActive sensors for heart rate, SpO2, ECG, and now blood pressure. Battery life sits around 40 hours with typical use, and it runs One UI Watch 6 on Wear OS. The display is bright and smooth at 60Hz. This is the watch most users should buy if they want a daily health companion at a reasonable price.
Galaxy Watch 8 Classic
The Classic model brings back the rotating bezel, which many Galaxy Watch fans consider the best physical input method on any smartwatch. It lets you scroll through notifications, apps, and health data without touching the screen, which is more practical in real life. The Classic also features a larger display, longer battery life, and a stainless steel case that feels more premium. For anyone who wants the full Samsung experience with better build quality, the Watch 8 Classic is the stronger pick.
Galaxy Watch Ultra (2025)
The Galaxy Watch Ultra is Samsung's flagship wearable, designed for athletes and outdoor enthusiasts. It uses a circular titanium case with military-grade durability ratings. Battery life extends well beyond two days, and it features advanced sensors for vascular stress monitoring, antioxidant tracking via the Antioxidant Index, and all the health tools found on the Watch 8. Blood pressure monitoring works fully on this model.
Galaxy Watch 7
The Watch 7 was the first Galaxy Watch to introduce dual-frequency GPS for significantly more accurate outdoor tracking. It also marked the debut of Samsung's BioActive Sensor 2.0, which improved health measurement accuracy across the board. While it has been superseded by the Watch 8, it remains an excellent option at a discounted price. Blood pressure monitoring is fully supported.
Older Models: Galaxy Watch 4, 5, and 6
These earlier models now gain blood pressure monitoring through the software rollout. If you own one, you now have access to blood pressure tracking at no extra cost. If you are buying new today, the Watch 7 or Watch 8 offers better sensor hardware, more features, and longer software support.

Samsung Galaxy Watch vs Apple Watch: Blood Pressure Compared
Both Samsung and Apple now offer wrist-based blood pressure tools in the US, but they work very differently. Apple's hypertension detection system, available on Series 9 and newer since September 2025, monitors for signs of high blood pressure and sends alerts when detected, rather than providing actual numerical readings.
Samsung's approach gives you real numbers — systolic and diastolic values — which is more informative for people who want to track specific readings over time. Apple's method works passively and does not require a cuff, which is more convenient. The trade-off is clear: Apple gives you an alert, Samsung gives you actual data.
For anyone invested in the Samsung and Android ecosystem, the Galaxy Watch is clearly the better choice for blood pressure detail. For Apple ecosystem users, the Apple Watch Series 9 and newer offer a simpler but less precise approach.
The Rollout: When Will You Get It?
Samsung launched this as a phased rollout beginning March 31, 2026. If you are not seeing it on your Galaxy Watch yet, you may have to wait a while longer as it reaches more users gradually. To check availability, open the Samsung Health Monitor App on your connected Galaxy phone and look for the blood pressure option inside the app. Make sure both your watch and phone have all available software updates installed.
Should You Buy a Samsung Galaxy Watch for Blood Pressure Monitoring?
If blood pressure monitoring is your primary reason for buying a smartwatch, the Samsung Galaxy Watch is a strong choice — but go in with clear expectations. You will need to purchase an upper-arm blood pressure cuff separately and commit to recalibrating every 28 days. If that workflow works for you, the Galaxy Watch gives you real, detailed blood pressure data on your wrist every day.
For most people, blood pressure monitoring is one of many reasons to choose a Galaxy Watch, not the only reason. Combined with ECG, sleep apnea detection, heart rate monitoring, and the broader Samsung Health ecosystem, the Galaxy Watch 8 or Watch 8 Classic is one of the most complete health wearable packages available right now.
