What are the best smartwatches to monitor blood pressure? Discover our recommendations to take control of your heart health.

Omron HeartGuide

Last Updated on September 12, 2021

We updated our selection of the best blood pressure smartwatches for 2021. We removed the Asus Vivowatch from it as it proves difficult to get in the US. When measuring your blood pressure with a watch, keep a critical thing in mind! Most of the watches will estimate your blood pressure using algorithms based on the Heart Rate Variability. Omron Heartguide is FDA cleared and relies on technology very close to the one used in a medical-grade blood pressure monitor. Always check your blood pressure with an FDA-cleared device or with your pharmacist or doctor.

Blood pressure (BP) is often referred to as the “silent killer.” Why? Because even when suffering from high blood pressure, you usually do not feel it. According to the American Heart Association, high blood pressure can lead to heart attack, stroke, vision loss, heart failure, kidney failure, and sexual dysfunction.

What are the benefits of a watch to monitor blood pressure?

If knowledge is power, checking your vitals regularly is the way to know and act appropriately. Blood pressure watches are a convenient way to get your health under control.

No need to go to the doctor’s office or the pharmacy anymore. Home blood pressure monitoring is already widely used and recommended by doctors for the effective management of hypertension. Some smartwatches are even cleared by the Food and Drug Administration (FDA), which guarantees the accuracy of the results.

In this article, we present what we think are the three best watches to measure blood pressure. The Omron Heartguide, Yamay 023, and Samsung Galaxy Watch 3 are our favorites. All of them synchronize the readings with an iOS or Android phone for easily sharing them with your doctor. Discover what they have to offer and why using them is a first step towards controlling hypertension.

The SAMSUNG Galaxy Watch 3 has everything you can expect from a modern smartwatch. It provides numerous health-related information, including Blood Pressure readings and Electrocardiogram (ECG). The watch is also one of the best fitness trackers and personal assistants on the market. We also love the design despite its bulky look. A watch to consider seriously and our favorite blood pressure watch for 2021.

4.5 stars

Price when reviewed: $349


The Galaxy Watch 3 is among the rare smartwatch on the market to offer the possibility for an FDA-cleared EKG that detects Atrial Fibrillation and Heart rhythms abnormalities. The Apple Watch and the Fitbit ones also benefit from this clearance.

The blood pressure monitor and the oxygen level monitor are somehow not FDA cleared. It means that the Galaxy Watch is not a medical device when measuring these parameters. Use it for information only, and when in doubt, double-check with your doctor.

With its stunning design and stellar healthcare capabilities, the Samsung Galaxy watch’s blood pressure is a serious contender and our overall favorite. With a vast catalog of watch faces to chose from, it is possible to find the one that will suit your mood or circumstances. The only drawback of the Samsung Galaxy Watch 3 lies in the battery life, which doesn’t last more than two days.

The watch is compatible with iOS and Android. It allows recording Blood Pressure using Pletysmophography (PPT). The YAMAY watch described below uses the same PPT technology. Even though the technological background is highly validated, the watch blood pressure sensor must be calibrated once every four weeks using a standard FDA-cleared Blood Pressure monitor.

When looking for a smartwatch offering the best for sport, fitness, health tracking, and the possibility of measuring Blood Pressure, the Galaxy Watch 3 should be on the top of your list.

More than a wearable blood pressure monitor, the Samsung Galaxy Watch 3 has everything you can expect from a modern health tracker.

The Galaxy Watch 3 is also reasonably priced. With the new Galaxy Watch 4 soon to be released, now is a perfect time to benefit from discounts.

The only drawback we can find is the relatively bulky design, more suitable for men than women.


  • Very intuitive UX
  • Rotating Bezel
  • Numerous fitness and health tracking feaures
  • Stylish design
  • Reasonnably priced


  • Quite bulky
  • Blood Pressure needs to be calibrated
  • Limited battery life

The OMROM HEARTGUIDE is undoubtedly the best blood pressure watch money can buy. The technology used is similar to the one found in home blood pressure monitors. However, as a fitness tracker, the number of features is somehow limited. Therefore, the OHG should be seen as a portable medical device that happens to track your fitness. This watch has two only drawbacks: it is expensive and is quite bulky to wear daily.

HeartGuide by Omron

4.5 stars

Price when reviewed: $499


Omron is not new to the world of blood pressure monitors. This Japanese company is one of the leaders when it comes to medical blood pressure monitors. Since its release on the market in 2019, the OMRON HeartGuide has received numerous awards. The 2019 TIME Invention Award, the 2019 Popular Science Best of What’s a new award in the Healthcare category.

To date, the Omron HeartGuide is one of the only watches, including a traditional inflatable cuff. If it was not enough, the OHG is also FDA cleared for accuracy.

The HeartGuide smartwatch is genuinely an all-in-one device. In an interview, the developers of this fantastic piece of technology said that “the OHG is not a wearable device. It is a blood pressure monitor that happens to be worn on the wrist.” We could not agree more.

The OHG is stylish but is large and bulky. It can become cumbersome when wearing it all day long. With a 4.1 oz or 115 grams weight and a watch dial of 1.9 inches in diameter, you will not forget that you are wearing it.

Once positioned on the wrist, it takes 15 seconds to get a reliable blood pressure measurement. The cuff comes in two sizes depending on your wrist size. So do not forget to measure your wrist and to buy the size that fits you best. The technology used to measure systolic and diastolic BP values include automatic oscillometric sensors and inflatable cuffs.

The app of the Omron HeartGuide

Cardiologists have validated the efficiency of the OHG according to the requirements of the American National Standards Institute Icnc./Association for the Advancement of Medical Instrumentation/ISO 81060‐2:2013 guideline.

To know more about the Omron HeartGuide blood pressure watch’s medical benefits, we recommended reading the excellent article written by Dr. Anthony Pearson published in the Skeptical cardiologist and our review of this disruptive watch.

When paired to the iOS or Android app, the OHG becomes an innovative fitness tracker as well. The companion app has the potential to improve medication adherence, track fitness, monitor sleep patterns, and help you stay connected with the world. With more than 80 patents under its belt, the Omron HeartGuide is the gold standard for tracking blood pressure everywhere and at any time.

This watch combines innovation and practicality. It redefines what wearable medical devices will be. Its only drawback, its price! At $499, the OHG does not come cheap. Yet, it is somehow an investment that you will not regret anytime soon. If you are serious about using a smartwatch to monitor your blood pressure, the Omron blood pressure flagship watch is a no-brainer.


  • Very accurate
  • Easy to use
  • FDA cleared
  • Only smartwatch with an inflattable cuff
  • Built quality


  • Quite bulky for everyday use
  • Pricey
  • Limited fitness tracking features
  • Battery life of 48 hours
  • App. only available in the US

The YAWAY 023 has a lot to offer. All of that for a very reasonable price. The technology used to measure blood pressure may not be as reliable as with the OHG, though. This smartwatch is an entry-level product, but when regularly calibrated, the YAWAY will not disappoint.


Price when reviewed: $44.99


Unlike the Omron HeartGuide, the YAWAY 023 smartwatch does not use an inflatable cuff to measure blood pressure. Instead, it relies on Pulse Transit time technology (PTT).

Without entering too much into the technical details, Blood Pressure is estimated by combining the heart rate and the blood flow at the fingertip. PTT relates to arterial stiffness and estimates the systolic and diastolic blood pressure. To ensure the reliability of the results, the watch must be regularly calibrated using a blood pressure reading coming from an FDA-cleared monitor.

This PTT technology is not yet cleared by the FDA but has received significant attention in recent years. When correctly set, the YAWAY 023 offers a full range of health data. For example, it records the blood pressure, blood oxygen level (blood saturation), heart rate and evaluates the stress levels.

The Yamay is a reliable watch that will not disappoint fitness enthusiasts. The battery life is respectable. You can expect up to one week between charges. As for the design, it reminds me of the Apple Watch. In a nutshell, the YAMAY 023 could be seen as an entry-level product to more prestigious brands.

The Yamay 023 is also waterproof, offers the ability to control the music playing on your smartphone, and notifies you when receiving calls or text messages. Despite its low price, it is a watch that has been well designed. Its blood pressure capability is the cherry on the cake.

The YAMAI 023 is a budget watch, of course, but for less than $50, it is hard to beat. Yet, the health analyses such as Blood Pressure, blood oxygen saturation, and heart rate will not be as reliable as what you may expect from a more pricey device. Still, they provide a good picture of numerous critical health parameters, blood pressure included.


  • Numerous health features
  • Stylish
  • Very good price
  • Long battery life


  • Needs to be calibrated regularly
  • Budget watch


The YHE BP Doctor is a newcomer on the market of the blood pressure smartwatch, but we are convinced that it will quickly become famous. The watch relies on an inflatable cuff, like the HeartGuide, and delivers very accurate results. Stylish and comfortable, it also comes with numerous applications to track your heart rate, calories consumption, and sleep quality. Most of all, it comes at a fraction of the price of the HeartGuide. A new wearable that needs to be considered very seriously.

We extensively reviewed the YHE BPDoctor and can not say enough good things about it. The BPDoctor watch relies on the same principles as the Omron HeartGuiode and includes an inflatable cuff. We compared the results of the readings using an Omron standard blood pressure monitor and were very impressed. The results of this watch were very close to a standard medical device.

This new wearable started initially as an Indigogo project and has very recently hit the market. We do not doubt that it will become a great success even though the market is still not as renowned as the more established brand.

We appreciated the design of the watch, which makes it elegant and comfortable to wear. Nobody will suspect that you are wearing a blood pressure watch. The cuff inflates very silently, and the measurement takes only a couple of seconds.

The BPDoctor also allows recording your activity level, sleep cycles, and Heart Rate Variability. Made in China, like most of its competitors, the YHE BP Doctor app. is very close to the one developed by Huawei, which is intuitive and functional.

We only regret that the associated app doesn’t allow yet to synchronize the results with Apple Health and that it is not possible to merge the workout data collected from other apps. The software still has room for some improvements but overall the YHE BPDoctor is an amazing BP smartwatch that can shake the current ranking of our favorite devices.


  • Inflatable cuff technology
  • Very precise
  • Comfortable to weat and stylish
  • Good battery life
  • Measure sleep cycles and HRV


  • Not possible to share the data with Apple Health
  • Strap may be too short for strong men
  • App could be better

What you should know

Are these really the best blood pressure watches?

The best blood pressure monitor will always be an FDA-approved or cleared medical device. A smartwatch will always be an alternative. When considering all the fitness watches offer, a balance needs to be found between your budget and expectations.

Wearable blood pressure watches have a lot to offer. However, always consider them to quickly obtain information about your blood pressure and not as a clinical device.

In case of doubts, the data will still have to be taken with a grain of salt. Always consult your doctor, pharmacist, or other healthcare professionals if your blood pressure needs extra monitoring.

What you should consider when buying a blood pressure watch?

Just as for any blood pressure monitoring device, there are various elements to consider when choosing the perfect device:

  • Accuracy: Accuracy is one of the key points to consider but not only. Don’t forget to calibrate the PPG watches regularly. When in doubt, the Cleveland Clinic advises taking three measurements at 30 to 60 seconds intervals. By averaging the readings, you will get close to what the real value is.
  • Extra features: A smartwatch opens the doors to plenty of applications such as fitness or calories tracking, heart monitoring, sleep tracking, and more. Balance the features and choose the smartwatch that is the most in line with your expectations and lifestyle.
  • Price: A FDA-cleared blood pressure monitor costs between $50 and $100 depending on the design, built quality, and associated apps. Except for the Omron, all the smartwatches are not designed mainly for blood pressure monitoring. Therefore, do not consider them as medical devices, and no need to break the bank for an additional function.


Are these watches accurate?

Most smartwatches rely on Photoplethysmography to estimate Blood Pressure. Once regularly calibrated, the algorithms will calculate the blood pressure using the heart rhythm variations. FDA clearance is a guarantee that the devices are as good as the current gold standards. Fitbit is currently conducting a study using a new technology called Pulse Arrival Time.

What are the pros and cons of Blood Pressure Watches?

We live in the age of the quantified self. Such devices offer a convenient way to track various health and fitness parameters at once. In addition, they can detect warning sins that will then need to be investigated in a proper clinical setting. The main drawback of these watches is that except for the Omron HeartGuide, they are not FDA-cleared. Therefore, the reading should always be seen as indicative. Never change your medications based on the results provided.

Why measuring Blood Pressure is essential?

High blood pressure is often seen as a behavioral disease. The modern lifestyle and diet are mainly responsible. Patients often do not know that they suffer from such pathology that can be controlled using efficient medications. Checking Blood Pressure is critical to avoid severe health consequences such as strokes or heart attacks.
