TOP 9 Best Smartwatches With Blood Pressure Monitor 2020

The market for smartwatches and fitness bracelets has hundreds, or even thousands, of different models. All of them help owners to monitor their body condition and lead a healthy lifestyle. The modern smartwatch is able to measure the heart rate, sleep, count steps, calories and distance, and more.

However, we are long required smartwatches with accurate pressure and heart rate measurement, but manufacturers are in no hurry to release the watches with these functions in mass production.

Even if the manufacturer wants to add the function of blood pressure measuring, it must obtain many permits from various health authorities. This is not always an easy task.

For example, the famous Japanese manufacturer of pressure measuring instruments Omron introduced Omron HeartGuide smartwatch for a blood pressure monitor. They are also known by the name Project Zero 2.0, back in early 2017. However, they received FDA approval (Food and Drug Administration) only at the beginning of 2019. As you can see, the process took about 2 years. Before that, there were more than 50 technological patents for smartwatch components and many other difficulties.

Therefore, there are not so many high-quality smartwatches that could accurately measure blood pressure. Of course, there are hundreds of cheap bracelets and watches from various Chinese brands. But often the accuracy of blood pressure measurement leaves much to be desired.

Before moving on to TOP 9 best smartwatches with blood pressure function, we should understand how it works.

How Does Blood Pressure Monitor Work in Smartwatch?

The principle of measuring pressure with a smartwatch is significantly different from measuring with a conventional sphygmomanometer. The smartwatch determines the pressure by mathematical analysis of the information received from the sensors. This is the velocity of the heart rate wave, its length, ECG, etc. After receiving the necessary data, it is transferred to a special mobile app. It automatically analyzes the information received, and displays the finished result on the screen of a smartphone or smartwatch.

The method was invented in the middle of the last century by the French scientist Etienne Jules Marey, and therefore received the name “Marey Method”. Now it is also called photoplethysmographic measurement of blood pressure. But, unfortunately, this measurement method cannot provide high accuracy and replace the “classical” one.

To obtain more accurate values ​​using photoplethysmographic measurement, it is desirable to follow a series of recommendations:

• Before the measurement, indicate your physiological data: gender, height, weight and date of birth. This data will allow the software to more accurately calculate the data.
• In the process of measuring, try not to move, not to talk and not to laugh.
• Measurement is best done while sitting with your hand at heart level.
• Before measuring, exclude from the diet any pacemakers (tea, coffee, etc.).
• For accuracy, repeat the measurement several times.

Why Do You Need a Smartwatch with Blood Pressure Monitor?

• A stylish gadget that does not look like a medical device.
• Convenient and easy to use.
• No special knowledge is required for blood pressure measurement.
• Fast measurement (30-120 seconds).
• Automatic measurement during the day.
• Measure heart rate and blood pressure anywhere and anytime.
• Saving history in mobile app.

How Accurate Are Blood Pressure Measurements on Smartwatches?

Unfortunately, there are no official statistics on the accuracy of measuring blood pressure. According to unofficial data, the average error is in the range of 20% or about 10 – 20 mm Hg. However, as we have seen from experience, the same smartwatch, when measuring the different users, can show different errors. Perhaps this is influenced by various physiological characteristics, for example, the depth of blood vessels, skin color, etc.

We figured out the theory, let’s move on to the smartwatches themselves. We tried to collect only the best smartwatches with blood pressure monitor. The smartwatches in this article are selected by online reviews and first-hand experience. However, you should understand that almost all of these smartwatches do not claim to be medical devices, so the data obtained with their help can be used solely for educational purposes.

Omron HeartGuide

Let’s start with Omron HeartGuide, which I mentioned above. This is a unique smartwatch with built-in blood pressure monitor. During the design process, Omron received more than 50 technological patents related to the miniaturization of all major components.

The principle of measuring blood pressure is practically no different from measuring with sphygmomanometer. Therefore, the results are obtained as accurate as possible.

Inside the strap, there are air cylinders that are inflated during the measurement process. According to the manufacturer, the cuff will withstand up to 30000 inflations. The last 100 measurements are stored in smartwatch’s memory. The data is also synchronized with Omron Connect mobile application.

In addition to pressure and heart rate monitor, HeartGuide can count steps, distance and calories, sleep, and notify you of incoming calls and messages. Information is displayed on a very simple and small LCD screen. Battery life is from 2 to 4 days.

That’s all advantages of the smartwatch. Unfortunately, HeartGuide is compatible with only iOS devices. Although the plans also include Android support.

At the moment, Omron HeartGuide is not sold outside the United States. The manufacturer doesn’t have a license to sell the smartwatch worldwide.

Finally, the price of HeartGuide is $499, which is a little expensive for a hybrid of a fitness bracelet and sphygmomanometer.

ASUS VivoWatch BP

This smartwatch doesn’t have an inflatable cuff. A system of two electrocardiographic sensors of a medical class and a photoplethysmographic sensor are responsible for the accuracy of measuring blood pressure.

If you want to measure pressure, just put your finger on the sensor on the front of the smartwatch for 20 seconds.

Right out of the box, accuracy may not be the highest. But, after calibration, it is within 5%, which is quite acceptable for a non-medical device.

In addition to pressure, ASUS VivoWatch BP can measure heart rate, sleep quality, track several exercise modes, notify of calls and messages, count steps, calories, distance. There is an alarm clock and several dial options.

VivoWatch BP is equipped with a 1.26-inch transflective screen and a battery life up to 14 days. The manufacturer ask for about $200 per smartwatch.

Conclusion

In fact, there are much more smartwatches with blood pressure monitor in 2020. You can find hundreds of wearable devices on Aliexpress from various brands and different price. However, most of them have inaccuracy measurement.

For example, when we tested MICROWEAR L7 smartwatch, it always showed 120/80 regardless of whether measurements were taken in a calm state or after exercise.

All smartwatches from our list try to accurately measure the blood pressure, although they are often mistaken. Therefore they cannot replace the sphygmomanometer.
