At the end of April, the Hykker Smartwatch was added to the Biedronka offer in two variants, round and rectangular. Over the past few days, I have had the opportunity to see how these devices work on a daily basis.
Summary | Final grade: 7/10
Hykker connected watch principally very cheap watchwho went to Biedronka with the prize 99 zlotys. While testing both devices, I kept this in mind and included it in the final review. Considering the purchase cost, which is the biggest advantage of the Hykker brand smartwatch, it deserves it praise for very good opportunities.
The tested watch (or rather watches) is a device that not only tells the time, but also tracks user’s physical activity. The equipment also includes an optical sensor that allows you to measure the pulse, as well as the degree of oxygen saturation and arterial pressure. And although the round copy of the latter completely failed, the rectangular watch gives hope of being useful in this area.
Of course, Hykker products have drawbacks. However – again – if viewed through the prism of price, their importance diminishes. If this watch only displayed the time, it could still be an interesting choice, for example due to water resistance if wearing comfort.
- No automatic screen brightness adjustment,
- Without pairing with a smartphone, you cannot set the time and date on the watch,
- The Da Fit app needs some refinement,
- Operation of the blood pressure measurement function,
- Long battery charging time.
- attractive appearance,
- Replaceable strap (you can use any size 22 or 20 mm, depending on the version of the watch),
- wearing comfort,
- Dust and water resistant to IP67 standard,
- Clear display,
- Features available,
- Very low price.
Hykker Smartwatch – appearance and specifications
As I already mentioned, the Hykker Smartwatch comes in two variants, which differ in appearance and display. The round version has 46 mm in diameter and 11 mm in thickness, and its mass is 35 g (with strap). The rectangular watch, on the other hand, is slightly smaller and has dimensions (approximately) 26 x 44 x 11 mm with a weight of 34 g (also with a strap).
The Hykker Smartwatch is equipped with a colorful screen, 1.3 inch TFT touch screen with 240 x 240 pixel resolution in the round variant and 1.69 inches diagonally and a resolution of 240 x 280 pixels in rectangular version. Either way, it’s on the side round function buttonwhich is used, among other things, to wake up or put the display to sleep or return to the previous screen.
The display is readable in all conditionsas long as we set the appropriate brightness. Unfortunately we have to do it manually in the watch settings because there is no automatic adjustment.
On the back of the devices are contacts for connecting the charger and optical pulse, saturation and pressure sensor.
Since each of the watches is very light, it is too very comfortable to wear. If you adjust the length of the bracelet correctly (size 22 mm in the round and 20 mm in the rectangular), you can completely forget that you are wearing something on your wrist. The case of the watch also deserves attention dust and water resistant to IP67 standard. Rain or splashes from these devices aren’t terrible.
When it comes to specifications of both watcheswhich – apart from the external characteristics – is identical, we also have here:
- Bluetooth 5.0 connectivity,
- 220mAh lithium-ion battery.
Included with the watch is sold charging cable and Polish-English User’s Guide.
First run, mobile app
To start the watch, just press the button it is equipped with. Provided the battery is charged, of course. The watch can theoretically continue to operate independently, but without pairing with a smartphone, it will not display the correct time and date. To connect the two devices, you must install in the phone memory DaFit app. The QR code with the link to the app can be found in the user manual.
Connection of the watch to a smartphone is provided very simple and everyone should take care of it. Once done, we can use the Da Fit app change watch settings, including changing the clock face. Their library is very rich, so everyone should find something for themselves.
The app also helps View recorded readings from sensors mounted on the watchincluding steps, sleep quality, heart rate, blood pressure and saturation. Here, too, we should be able to preview our formation – at least that’s what our intuition tells us. Unfortunately, however, I could see here only workouts initiated on the smartphoneand the only choice was run in the fresh air. Here and there you can also come across a not very correct translation of the application into Polish.
Using the watch
The main use of the watch interface is touchscreen. Being on the main screen on the left, we slide app menu. The list includes Heart Rate, Exercise, Pressure, Saturation, Weather, Camera, Player, Breathing, Games, and Settings, with the latter option including Stopwatch, Alarm Clock, and Countdown. countdown). This is the case of a round watch. On a rectangular watch, the apps were pulled from the settings. There is also a flashlight function. The screen then lights up white with maximum brightness.
To the right of the main screen we have the results of the various measurements, functions for taking a photo remotely with the smartphone camera or controlling the on-board music player, as well as the Breathing function (helping to relax) and the weather girl. We have put in advance panel with quick settingswhile the bottom notification center. Here we can see the notifications of the application, which we activate in the Da Fit settings, such as Phone, Messages, Facebook, Twitter or WhatsApp. Enabling or disabling are the only available options related to notifications from selected apps.
Available functions and their quality
Hykker smart watch can track 6 types of physical activityincluding swimming. Please note that there is no GPS receiver herethus, the displayed distance – if displayed – directly depends on the number of steps and stride length in the user profile settings. As for the pedometer itself, this I compared it with the indications of the Samsung Galaxy Watch4 Classic and in general the values in Hykker were more or less a quarter less.
Pulse or blood saturation measurements were comparable. The watch can measure heart rate on demand or automatically every 5 to 30 minutes. The automatic measurement results can be tracked in the Da Fit app (“full heart rate” section). As for blood pressure, it’s a round clock set at 140 mmHg for systolic blood pressurewhile the rectangular watch showed at this point values even over 20 mmHg inferior to Samsung and cuff blood pressure monitor.
You can read more about blood pressure measurements in my column at this address.
As for other features, other than the issues I described earlier, everything seemed to work fine.
The Hykker smartwatch is powered by a built-in rechargeable battery 220mAh. During normal use of the watch, paired with a smartphone, it was enough for me for about 6 days. The reduction of this time is influenced, among other things, by the frequent recording of training sessions, during which the heart rate monitor operates in continuous mode. In turn, it is used to extend working time Energy saving mode (in the Da Fit app).
Built-in battery charging time from 0 to 100% totals about two hourswhich is long. It is enough to reach 50% Less than 30 minutes.
