Biedronka shot in action. I checked the gear they’re sweeping off the shelves

Last Thursday, a new Hykker smartwatch in a round and rectangular screen version arrived in Biedronka stores. Both devices, although costing less than 100 PLN, can measure blood pressure. How do they do it? I decided to check.

Hypertension is an increasingly common disease of civilization in the world, with which I have been treating myself for many years. Data from the National Health Fund show that in 2018 they were affected by this disease 31.5% of adult Poles – 9.9 million people. It is estimated that about 95% of cases of hypertension are primary, which means that its cause cannot be clearly determined. It is also a serious disease that may not be treated lead to many serious diseases and even kill.

Although there is a lot of information on the internet on how to treat high blood pressure at home, treating high blood pressure involves taking the right medications to regulate your blood pressure. It is also important check blood pressure regularlyin which – at least in theory – it should help a watch with the appropriate function.

A Biedronka watch as a blood pressure monitor

MPTech has launched its new smartwatch on the Biedronka network. Hykker connected watch it is available in two versions that differ in shape – one is round and the other rectangular. The price is the same in both cases 99 PLNit’s the same too set of functions available. Among them is blood pressure measurement, a solution that hasn’t been found in any Apple Watch so far, costing dozens of times as much. However, the American giant is working on a suitable solution.

And how does this feature behave in penny watches? I checked it by doing simultaneous measurements using a smartwatch (left hand) and an electronic blood pressure monitor with a cuff on the arm (right hand). For comparison, I also reached the watch that I use every day Samsung Galaxy Watch4 Classicwhich can also measure blood pressure, but costs several times more of the Hykkers. Additionally, Samsung’s solution requires calibration from time to timewhich consists of measuring the pressure three times simultaneously with a watch and a “normal” manometer with armband. Hykker Watches they don’t have that option.


So let’s get to the results. First, the Galaxy Watch4 Classic, calibrated the day before. I have listed the results of four sets of parallel blood pressure measurements in the table below. All values ​​are listed in millimeters of mercury (mmHg).

Measure number Watch Blood pressure monitor with cuff
1 124/78 126/81
2 129/82 128/80
3 128/80 133/80
4 131/83 131/76

As you can see, the Samsung Watch is quite good for controlling blood pressure. From my own observations, I can add that two things are important here so that the measurement results are more or less in line with reality:

  • you must calibrate your watch regularly,
  • the watch should be more or less in the same place on the wrist when measuring blood pressure as when calibrating.

Now the time of Hykker watches. Although the two devices are theoretically the same in terms of equipment, they do not measure pressure as well – at least that is the case with the units I received for testing.

Measure number Round Hykker connected watch Rectangular Hykker Smartwatch
Watch Manometer Watch Manometer
1 140/78 146/86 112/73 128/75
2 140/80 143/85 108/70 131/75
3 140/85 145/82 109/71 128/79
4 140/82 139/81 109/73 127/77

At first glance a round watch was better. His measurements were usually slightly lower than what the cuff blood pressure monitor showed, but there were differences did not exceed a few mmHg. However, the systolic blood pressure was 140 mmHg each time, also in the other measurements I took that day. The rectangular watch, on the other hand, indicated the blood pressure lower up to 20 mmHg or morebut he did not settle on a single value like his round brother.

Can the pressure be monitored with the watch? Yes, but not everyone

Sometimes I hear opinions from different sides that the watch cannot correctly measure the pressure, whether it is a device for almost 2000 PLN or for less than 100 PLN. Alone though I can’t subscribe.

As someone with high blood pressure, I regularly measure my blood pressure with the Samsung Galaxy Watch4 Classic, sometimes comparing the results with what the blood pressure monitor shows with the cuff. There are differences in such situations, but they usually do not exceed a few millimeters of mercuryso they can be omitted. It should be remembered that blood pressure is variable and even the results of two measurements carried out successively with one device may differ from each other.

Hykker Smartwatch, two watches and a blood pressure monitor

Are cheap Hykker watches also suitable for blood pressure monitoring? round watch definitely notbecause constantly showing the same systolic pressure. However, that may be the problem with this particular copy. In the case of a rectangular watch, it is contrary to appearances much betteras the displayed values ​​change. Whenever I compared its readings to a blood pressure monitor or a Samsung watch, they were lower and the differences fluctuated over the range. from a few to more than 20 mmHg.

Note: Hykker watches with blood pressure measurement function are not medical devices, so their indications should be checked with a medical blood pressure monitor. Also, do not make the decision to change the dosage or stop using your medications without consulting your doctor.
