TOP 10 fitness bracelets with blood pressure measurement in 2021

How does a fitness bracelet measure blood pressure?

You need to understand that finding a fitness bracelet that will perfectly measure blood pressure is almost impossible. They will all have a certain error and cannot compare with an automatic or mechanical blood pressure monitor. The reason is completely different measurement methods.

Conventional blood pressure monitors are equipped with a cuff that allows you to determine the upper and lower values ​​of blood pressure by shocks and changes in pressure in the cuff. Smart watches and fitness bracelets, with very rare exceptions (Omron HeartGuide), do not have such a cuff and, in fact, pressure is not measured, but is calculated by software based on the indicators of heart rate sensors, rhythm and pulse wave speed.

You can read more about how a fitness bracelet measures pressure, the principle and accuracy of operation in this article.

Important! A fitness bracelet with a blood pressure monitor is not a medical device! It is not recommended to use the data obtained with its help to adjust treatment or take medications. For informational purposes only.

How to take a measurement

Manufacturers of wrist gadgets have made sure that the process of measuring pressure is as simple and convenient as possible. Indeed, among potential users there is a fairly large segment of elderly people for whom this is especially important.

Most often, you can start the measurement process in two ways:

• From the application. To do this, you need to go to the application for this gadget. Next, you need to select the “Blood Pressure” section and click on the “Measure” button. Since each manufacturer develops a unique application for its bracelet, suitable only for this device, the names may differ. But the general principle is the same everywhere.
• Directly on the bracelet. First, on the bracelet screen, by scrolling, you need to select the pressure measurement function. This can be done using screen touches or control buttons. Having selected the appropriate function, you must activate the process by pressing the screen or button.

Measurement accuracy and error

The accuracy of measuring pressure with a fitness bracelet largely depends on the fulfillment of a number of conditions and recommendations:

• Indicate in the application your height, weight, age, gender and normal blood pressure at rest;
• Before taking measurements, you should not drink tea, coffee, or energy drinks;
• Ensure that the sensor fits as tightly as possible to your hand;
• Before measuring, you need to sit down and fix your hand at heart level;
• During the measurement, try not to talk or move.

Accuracy is also affected by factors such as physical activity, emotional stress, medications, etc.

When all these recommendations are followed, the measurement error is on average 10-15%. That is, you definitely shouldn’t expect 100% accuracy, but the results will be enough to understand whether the indicators are within the normal range.

Find out the price

GSMIN WR11 (2020) is the successor to the fairly popular WR11 fitness bracelet, released in 2021. The 2021 model has many features and capabilities, the main ones being:

• Optical heart rate sensor;
• PPG sensor for measuring pressure;
• Sensor for taking ECG;
• Accelerometer for counting steps, calories and distance;
• Sleep quality assessment;
• Weather forecast;
• Alarm;

GSMIN WR11 is equipped with a 0.96-inch TFT color screen and this is one of the main disadvantages of this gadget. These types of screens fade greatly in bright light, making information difficult to read. There are no such problems indoors.

Despite the impressive functionality, the autonomy of the bracelet is not bad. One charge of a 130 mAh battery is enough for 5 – 7 days of autonomous use, depending on the intensity.

As for accuracy, judging by the reviews, the error in counting steps, calories and pulse is approximately 5%, and the error in measuring pressure, subject to all the above recommendations, varies from 10 to 15 units.

This fitness bracelet is available in 4 colors: black, blue, red, green. Price – 5,900 rubles in the Gsmin online store.

Pros:

• Impressive functionality
• Good accuracy of blood pressure measurement
• ECG function
• Charging via USB port
• 12 month warranty

Minuses:

• High price
• Only three sports modes
• The screen goes blind in the sun
• IP67 protection not suitable for swimming

Instrument accuracy

Models from different manufacturers have different accuracy in measuring blood pressure. By the way, fitness bracelets are not required by law to accurately take readings, or at least have an error within strictly specified limits. The fact is that gadgets do not belong to the class of medical devices, and therefore there are no corresponding requirements for them.

However, some models are capable of providing fairly accurate readings, such as GSMIN fitness bracelets. And this is an initiative exclusively of the manufacturer, who cares about the level of sales of its products.

Comparison rules

You can check the error of the fitness bracelet when measuring pressure yourself by taking a comparative measurement. You need to compare it with the readings of a medical device. At the same time, many people incorrectly compare the gadget and the tonometer. Here are the basic rules that will give the most accurate picture:

• Measurements with a tonometer and gadget should be carried out on one hand. The pressure on different hands is slightly different.
• Between measurements, the subject should not walk, speak intensively, or laugh. This will lead to a change in the state of his circulatory system and, as a result, the pressure may increase.
• The measurement should ideally be taken at the same location on the arm. This is more difficult to implement. A conventional tonometer takes measurements above the elbow, and the pressure there is slightly lower than at the wrist. This also needs to be taken into account.

In addition, you need to understand that the medical device that is taken as a standard also has measurement errors. This value must be indicated in the product passport.

The most accurate device is considered to be a mechanical tonometer with a phonendoscope. But it is now becoming less and less common, since you need special skills to use it correctly.

No.1 DT58 – fitness bracelet with accurate blood pressure measurement

Key Features

• Year of release: 2019
• Screen: color, LCD IPS

DT58 is one of the no-name fitness bracelets that is sold under many brands and names. In stores it can be found under the name KSUN KSS701, SMART NEOBAND, etc. We had a copy from brand No.1 for review, and we have to admit, we liked the bracelet.

No.1 DT58 is equipped with a 1.14-inch diagonal color screen with a resolution of 240*135 pixels. Unfortunately, it is not touch sensitive. You can switch between functions using the touch button at the bottom of the screen, which also serves as an electrode for the ECG function. Another electrode is located on the back panel, next to the optical heart rate sensor.

During testing, the DT58 showed fairly high accuracy in measuring pressure. The deviation of the values ​​was approximately 5 - 10 units, which is very good. The pulse is also measured quite accurately. But with steps and calories, not everything is so simple. On average, the bracelet added about 10 – 15%, taking into account the “false” steps.

In addition to standard functions for a fitness bracelet, the DT58 also provides information about the weather, altitude, barometric pressure and even ultraviolet radiation levels. At the beginning of this year, a PRO version of the fitness bracelet was also released, in which all existing sensors were joined by a temperature sensor that measures body temperature with an accuracy of 0.1 degrees.

No cables or charging cradle are needed to charge the device. Under one of the halves of the strap there is a USB port that can be connected to the connector of a laptop, Power Bank or power supply. One charge of a 120 mAh battery is enough for 5 - 7 days of active use.

Check price

SG2 Smart Watch is a new, but very promising smart watch model. Having very good characteristics and an impressive set of functions, the price of the device is quite affordable. This model is sold under many different brands, such as HerzBand, Lemfo, Microwear, etc.

Externally, the SG2 is a complete copy of the popular smartwatch Samsung Galaxy Watch Active 2. But, although the gadget looks like a watch, it is still more of a fitness tracker in the form of a watch. They do not have a full-fledged operating system, there is no ability to install additional applications, there is no GPS and memory for storing music. Nevertheless, the watch deserves attention.

They were equipped with a round AMOLED screen with a diameter of 1.19 inches with a resolution of 390*390 pixels. This is very rare for smartwatches in the budget segment. The Nordic nrf52840 processor, which can be found in many fitness bracelets, is responsible for performance.

The watch is powered by a 230 mAh battery. One charge is enough for 5 – 10 days of battery life, depending on the intensity of use.

Detailed Specifications of SG2 Smart Watch

Pros:

• Cool design
• High-quality AMOLED screen
• Lots of features
• IP68 protection
• Reasonable price
• Wireless charger

Minuses:

• Low battery life
• During training, the pulse sensor “lies”

Analysis of results

Similar screening examinations based on optical measurement of heart rate show fairly accurate results and are actively used for early diagnosis of body pathologies in many modern medical centers. However, in practice, you can notice that not all fitness bracelets adequately cope with the role of a heart rate monitor, therefore the information obtained with their help can only be used for informational purposes. You can collect and study statistics in a special application, based on which you can choose a training regimen that is more effective for you.

To better analyze your health, you should not only trust mobile gadgets in the form of trackers or smart watches, but also rely on your own feelings. If you clearly feel unwell, reduce the intensity of your workout or stop it altogether, even if the device’s sensors record normal values.

DT35 Smart Watch

Brief characteristics

• Year of release: 2020
• Screen: color, LCD
• Diagonal: 1.54 inches
• Resolution: 240*240 pixels
• Processor: MTK 2502D + BMA 425
• Battery: 260 mAh
• Battery life: 2 – 5 days
• Water protection: IP67
• Sensors: accelerometer, heart rate monitor, ECG sensor
• Price: from 23$

Check price
The DT35 is another gadget that isn't tied to a specific brand, and another one that looks like a smartwatch but is essentially an activity tracker. This time the design is blatantly copied from Huami's Amazfit GTS.

The tracker has a rectangular body made of zinc alloy. The device is equipped with a silicone strap or a Milanese weave metal bracelet. If desired, the strap can be replaced with any other bracelet or strap 20 mm wide. The housing is protected from water and dust in accordance with the international standard IP67. Splashes and exposure to rain will last for hours, but you should not swim with them.

The device is equipped with a bright 1.54-inch LCD screen with a resolution of 240*240 pixels. Under the hood there are a pair of processors: MTK 2502D and BMA 425. Using two processors, the manufacturer tried to achieve maximum performance and battery life. The 260 mAh battery allows you to use all available functions from 2 to 5 days without recharging.

If you believe the reviews, the accuracy of pressure measurement is at a fairly high level. The heart rate sensor and pedometer also cope well with their tasks. But the ECG is an ordinary toy that you should not rely on.

In terms of features, the DT35 is practically no different from the SG2 Smart Watch. The main difference is the presence of a microphone and speaker for Bluetooth calls. There is a heart rate sensor with support for blood pressure measurement, an accelerometer, an ECG sensor and a blood oxygen level sensor.

23.53 - 24.60$ on Aliexpress

24.99 - 30.99$ on Aliexpress

Pros:

• Stylish design
• Large, informative screen
• Large number of sensors
• Microphone and speaker for Bluetooth calls
• Affordable price

Minuses:

• Low battery life
• ECG sensor for "tick"
• The screen goes blind in the sun
• IP67 protection not suitable for swimming

General rules for measuring pressure

It is important to use any device correctly. Here are a few rules that you should follow:

1. Do not perform active physical activities for 30 minutes before the measurement.
2. Monitor the position of the bracelet - it should be pressed tightly to the wrist.
3. Remain calm while readings are taken and remain silent.
4. The hand on which the measurement is taken does not need to be strained, it should be relaxed.

“Why,” someone might ask, “follow these rules? Maybe I’m interested in knowing what my blood pressure is right after a run.” This is possible, but you need to remember or make notes about these points. After all, the results are saved and then displayed in the form of graphs of pressure changes during the day, week, month. Such “jumps” can significantly distort the overall picture.

GSMIN G20 (2020) – fitness bracelet with accurate measurements of pulse, pressure and ECG

Main characteristics

• Year of release: 2020
• Weight: 30 g
• Screen: color, LCD

Check availability and price

GSMIN G20 (2020) is an excellent model for those who focus on monitoring the body’s condition. According to the manufacturer, the gadget is equipped with ultra-precise sensors similar to medical devices. I can’t fault the design either – the bracelet looks really cool.

The main feature of this gadget is its multiple uses. It can be worn on your hand, like a regular fitness bracelet, and attached to your chest using special adapters for more precise control of your body’s condition during training.

The tracker is equipped with a bright, color LCD screen with a diagonal of 0.96 inches. Below the screen there is a touch button – an electrode for taking an ECG. In addition to the ECG, the bracelet has all the functions necessary to monitor daily activities. He can:

• Assess the duration and quality of sleep;
• Monitor several sports modes;
• Measure the number of heart beats;
• Monitor the balance of oxygen in the blood;
• Count the number of steps taken;
• Calculate the number of calories burned and distance traveled;
• Notify about calls and messages.

The plastic case is protected from water and dust according to the IP67 standard, which means you should not use the tracker while swimming. This is the first flaw of the G20. The second drawback is that the gadget is not cheap. It can be purchased in the GSMIN online store for 7,900 rubles. But there are also a number of advantages: accurate sensors and a 12-month warranty from the store.

Pros:

• Cool design
• Bright screen
• High precision sensors
• Multiple wearing ways
• Official guarantee

Minuses:

• Price is above average
• IP67 protection not suitable for swimming

Which hand to wear

The sports bracelet is equipped with functions that involve measuring the physiological state of a person, as well as his level of activity. That is why it is worth following the simplest rules for wearing a gadget to minimize errors. If an ordinary watch can be worn on any hand, then with fitness bracelets there are certain nuances.

When answering the question on which hand the fitness bracelet is worn, it is impossible to say unequivocally on the left or the right. It all depends on the person. It is best for the device to be fixed on the less active hand. That is, it is better for a right-handed person to wear it on his left, and a left-handed person to wear it on his right wrist.

Interesting! The less active the hand, the smaller the measurement error.

The reason for wearing the device on your inactive wrist is the way it works. Even the most budget bracelets, which lack the functions of measuring blood pressure and heart rate, have a built-in pedometer. It, in turn, realizes the capabilities through the use of devices such as an accelerometer and a gyroscope. The pedometer measures the number of steps not by the movement of the legs, but by the movement of the arms. The fact is that when taking a step, a person duplicates it with a wave of his hand. It is by counting the number of such swings that it is determined how many steps have been taken. Pedometers are imperfect, so they can count a simple wave of the hand as a step, even when a person is standing or sitting. The inactive hand moves little, so the number of fake steps counted will be much smaller.

Almost the same reason forces you to wear a bracelet on your inactive hand in order to obtain more accurate results of measuring pulse, blood pressure or ECG. The optical technology used in the devices allows you to obtain the most accurate data only when your wrist is relaxed. The movements of the active hand occur more intensely. Muscle work disrupts blood circulation. Tight muscles create additional complications, so the measurement results may be overestimated.

HerzBand Active ECG 3

Main characteristics

• Compatibility: Android, iOS
• Screen: color IPS.
• Diagonal: 1.14 inches.
• Sensors: accelerometer, optical heart rate sensor, blood oxygen level sensor, ECG sensor.
• Water and dust protection: IP67.
• Battery: 130 mAh.
• Autonomy: up to 5 days of normal use.
• Price: 5,930 rubles.

HerzBand Active ECG 3 is a modern and very functional fitness bracelet for those who monitor their health and try to lead a healthy lifestyle. It has a wide range of functions, quite good characteristics and high measurement accuracy.

The device is equipped with a bright 1.14-inch diagonal IPS color screen, the information on which is easy to read even in intense sunlight. Below the screen there is a touch-sensitive metal button, which also serves as an electrode for taking an ECG. Two more electrodes are located on the back of the case, next to the heart rate sensor and contacts for charging using a magnetic cable.

The kit comes with an additional docking station and a pair of Velcro electrodes. With their help, you can get the most accurate ECG and HRV measurements by attaching the gadget to your chest. Also, for greater convenience, you can purchase an additional chest strap.

The fitness bracelet can measure heart rate and blood pressure, both in real time and around the clock, at certain intervals. There is also a function to measure blood oxygen levels. At night, along with SpO2, the respiratory rate, load on the heart, the level of hypoxia and apnea (interruption of breathing during sleep) are determined.

As testing showed during the HerzBand Active ECG 3 review, the built-in sensors and software provide fairly high measurement accuracy. I especially liked the sleep monitoring function and oxygen level measurement. However, it is worth noting that the data obtained cannot be used for diagnosis, prevention and treatment of diseases, and are for informational purposes only.

The functionality standard for most fitness bracelets is also present:

• Step counter;
• Determination of calories burned and distance traveled;
• Assessment of sleep quality and duration;
• Jogging tracking;
• Controlling your smartphone's music player;
• Timer;
• Stopwatch;
• Alarm;
• "Find phone" function.

A 130 mAh battery is responsible for the autonomy of the device. One charge, depending on the intensity of use, will last up to 5 days of battery life.

Bracelets for the treatment of hypertension: what is on the market and do they help?

Today you can buy pressure bracelets in almost all pharmacies and on the Internet. This is a chain of magnets (from 8 to 30) framed in metal (from medical steel to platinum), sometimes inlaid with semi-precious and precious stones.

Manufacturers of such accessories claim that their products can cure a wide variety of diseases (diseases of the joints, digestive system, nervous pathologies, immune disorders, cardiovascular disorders, including hypertension).

The mechanism for lowering blood pressure supposedly occurs due to the effect of magnets on blood iron, as a result of which its viscosity decreases, systemic blood flow improves and tissue hypoxia is eliminated. This ultimately leads to a decrease in blood pressure.

In fact, ferric iron, which is part of hemoglobin, has low magnetic properties due to the isolated arrangement of atoms in the hemoglobin molecule and the low concentration of the element in the blood.

The magnetic force of such “gadgets” is less than 0.2 Tesla, which can change the viscosity of the blood by no more than 0.02%, and this does not allow us to count on any positive effect from wearing medical bracelets.

Positive reviews and healing stories are attributed to the placebo effect. A noticeable disadvantage of the existence of such bracelets on the market is the fact that some easily suggestible hypertensive patients, believing in the healing power of magnets, refuse drug treatment.

Magnetic bracelets are strictly forbidden to be worn by patients with an implanted cardioverter-defibrillator and artificial pacemaker, as well as with pustular diseases of the hands, eczema, and dermatomycosis.

Another type of pressure bracelets are all kinds of copper products and jewelry made from organic minerals (malachite, chrysolite, jade, obsidan, chrysopase, sapphire, hematite, aventurine, pearls, carnelian). Their relationship to blood pressure is also questionable. Although it is worth noting the positive impact on a person’s psycho-emotional background when wearing a beautiful accessory.
