TOP 10 fitness bracelets with blood pressure measurement in 2021

Smart watch manufacturers are not in vain trying to focus these multifunctional gadgets on human health. Modern people try to take care of themselves, and smart technology helps them do this not from time to time, but constantly - even around the clock, if necessary. Smart watches are indispensable for hypertensive and hypotensive patients, especially in cases where the pressure can “jump”: on an airplane or while jogging, while walking or hiking. Don't carry a blood pressure monitor with you everywhere.

Such models can also be useful for athletes - they help avoid dangerous overloads during training. A smart watch with a blood pressure monitor is also indispensable for older people: it will help them see a doctor on time.

However, most pressure-measuring “bracelets” synchronized with a smartphone are still not medical equipment. In many models, the tonometer function is just a nice addition. And they, unlike a medical device, do not measure pressure using cuffs, but calculate it like a calculator using a formula, based on the readings of sensors built into the body and biometric data that you enter into a special application on your smartphone. And it works like this: the sensor emits a light signal, it penetrates the skin, and the device records the pulse rate, the rate of dissipation of the pulse wave and the light transmittance of the blood. And then it’s pure mathematics. The more correct the source data, the more accurate the calculations. It was the accuracy of the indicators that we took as a basis when compiling a rating of smart watches with pressure measurement.

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.

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.

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.

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.

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.

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.

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.

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.

• 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.

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.

Bizzaro is one of the projects of the Canadian company Rekam Inc. Canada. The first smartwatches under this brand were introduced back in 2014, and since then, the range of Bizzaro wearable devices has been constantly expanding. But, although it is a Canadian brand, the Bizzaro F590 fitness bracelet is manufactured in China, and what's more, it is sold under many different brands. For example, the GSMIN online store sells it under the model number WR11 (2019).

The device was equipped with a color OLED screen with a diagonal of 0.96 inches and a resolution of 160*80 pixels. It's bright enough and doesn't fade as much in the sun as most LCDs. Below the screen there is a touch button - an electrode for the ECG sensor.

Some buyers complain about the low accuracy of the bracelet's pressure measurements. But, after calibration in the application and following all recommendations, you can achieve an acceptable error.

The bracelet can:

• Take an ECG;
• Measure heart rate around the clock;
• Monitor sleep;
• Measure pressure;
• Count steps, calories and distance;
• Determine the HRV index (general body condition).
• Notify about calls and messages.

Device price: from 4,000 rubles.

Pros:

• Vibrant color screen
• Multifunctionality
• Determination of the HRV index
• Blood pressure measurement and ECG recording

Minuses:

• Non-touch screen, one button control
• Weak vibration

Storage and care

The blood pressure bracelet needs to be cleaned periodically to ensure accurate readings.

It is better to remove dirt with a soft damp cloth without using aggressive chemicals. The display is wiped with microfiber or a soft, lint-free cloth. Excess moisture is removed using a cotton swab. If you need to clean the inside of the device, the case can usually be disassembled. At the end of all procedures, it is recommended to use a vacuum cleaner to remove residual dust, moisture and microparticles. It is forbidden to dry gadgets with a hairdryer, as high temperatures can damage the parts.

Smart bracelets are worn on the wrist. Most models are worn throughout the day, without being removed during training, sleep or water procedures. Battery life and the need for recharging depend on the individual characteristics of the device. The optimal operating temperature range is from 0 to +35 with a humidity of no more than 90%. Signs of unstable operation are observed at -10 degrees.

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.

GPS bracelet for the elderly - a device for remote control

GPS beacon for seniors provides passive protection. After all, those who have health problems can get injured outside the home: while walking, on the way to the store. A bracelet for the elderly with a panic button and GPS function will tell relatives the coordinates of a loved one’s location. Thus, you can obtain information promptly and avoid many problems and worries.

The device operates on the principle of a GPS beacon: it measures the owner’s location coordinates at certain intervals and sends them to a mobile phone or computer. There are bracelets with asynchronous triggering that send information not regularly, but in certain cases:

• a signal is received from the shock sensor (triggered when falling);
• an elderly person has gone beyond the boundaries of the geofence, which he should not violate to ensure safety;
• a request for coordinates was received from an observer.

The measurement error is 10–15 meters when determining the location of the carrier.

A GPS tracker for older people provides a number of advantages, since it not only measures coordinates at a specific point in time, but also remembers the route of movement. Unlike a beacon, it operates in active mode around the clock, so it consumes an order of magnitude more electricity and needs timely recharging. If an elderly person wanders far from home or the fall sensor is triggered, regardless of his location, relatives will immediately receive a message about the incident and will be able to provide the necessary assistance based on the received coordinates. Many GPS tracker models allow you to establish contact with someone close to you by pressing one button. Bracelets of this kind are very effective when an elderly person suffers from memory loss, is prone to getting lost, or is prone to wandering.

The main advantage of these devices is that they are safe for people, even with constant use, since the electromagnetic radiation is many times weaker than that of a cell phone. They cannot provoke the appearance of any disease; on the contrary, their main purpose is to improve life, make it safer and calmer.
