Concerned about the bracelet for a long time, has not been started because most are just a pedometer, you need to open the phone app to view the number of steps, or else there is no heart rate; or with the heart rate is not real-time heart rate, just interval measurement. Or have it, but no sedentary reminder - sedentary body ah.
Until the new coarse grains and bong come out, completely meet the requirements. But has always been in conflict with monkeys, so it still started in Beijing East bong3. Calculate 8.30 single to now has been a month, the functional groping almost, talk about their own requirements and the gap and experience, but also considered a moderate experience .
Let's talk about heart rate first. This is what 俺 俺 has always valued most. First of all, to be accurate, otherwise it will be meaningless; secondly, it is necessary to measure the real-time heart rate, so as to be helpful to one's own sports.
Talk about accuracy first. Bracelet heart rate accuracy then there must be a standard test method or other recognized more accurate equipment comparison. So compared with the polar H7 heart rate band in hand and non-exercise heart rate. H7 has previously been compared with the Omron sphygmomanometer, readings are the same, can be used as a reference.
In sit-in or non-movement state, the measured values ​​are consistent. For example, the measured meditation heart rate of Polar 75 by Polar, and the measured value of 72 by the wristband, sometimes by 78, can be considered consistent.
The overall heart rate is consistent during exercise. Polar connection runtastic, running 25 minutes, an average heart rate of 160, maximum 173, bracelet running average heart rate of 158 at the same time, we can refer to the following figure red box contrast. Since they are all set on the phone, the bracelet time lags slightly by 1 minute. However, it was later discovered that this product can automatically identify the sport mode, sit still, or run, or walk without manual selection in the app. However, identification is not immediate, and it takes almost one minute duration. This should be to prevent false triggering.
However, a problem was found during running. The maximum heart rate measured in the wristband was about 160, not reaching 170. Secondly, real-time comparisons were made during running and it was found that the heart rate was consistent for most of the time, for example, the wristband showed 150, and the polar display. 155, this probability is about 1/2; 1/4 of the time gap is relatively large, for example, the bracelet shows 150, polar 165, but then the bracelet measured value will gradually be consistent with polar; another 1/4 chance is both There is a wide gap between them and they will not converge.
It seems that in terms of accurate heart rate, there is no problem with daily heart rate; vigorous exercise such as running has a 3/4 chance of accuracy. It is estimated that running sweat or wearing tightness has an effect on the measured value.
In addition, I found that heart rate measurement takes a relatively long time, and it takes approximately 20-30 seconds from the start of measurement to the final reading. It is speculated that the real-time heart rate measurement promoted by the manufacturer is not real-time, but it takes a sampling time. If the heart rate fluctuates due to a change in state during exercise, especially if the heart rate fluctuates, especially if the undulations are large, the wristband heart rate measurement time may be prolonged, or the previously measured values ​​may not be accurate, and the later period may increase with the sampling time, or the movement state may be stable, and the wristband may be measured. The value is consistent with the polar heart rate band. For example, running first, and then walking, the heart rate will change at this time, which is why the first occurrence of the wristband is inconsistent with the polar heart rate band, and the reason why the readings tend to be the same.
Trying to install the millet bracelet with the runtastic method tried to establish a close relationship between bong3 and runtastic, and could not be successful, a little disappointed. There are knowing little partners, please enlighten.
When the first version of bong3 software comes out, the heart rate will be measured at intervals. However, the later version has been modified. The curiosity drives the test, and the direct reminder is accurate.
Well, another way of thinking, since the wristband heart rate measurement is light, if it is measured in space, there will be no loss of light, relative to the blank. Let's try colored things and look at the absorption of light. Wearing a little half bottle of six god, or so, it seems that the new firmware is to upgrade the heart rate light threshold. I would also like to try a piece of pork but it does not make sense to think about it. First measured how? Even if the heart rate is measured across the air, but it does not affect the actual heart rate, it can only be said that it is not rigorous. Second, the reason I didn't measure on pork was because I was lazy
After the important talks are over, we continue to work hand in hand with other areas.
Then talk about wearing . Although the screen is flat, but the back of the bracelet is a small arc, close to the arc of the wrist, so wear does not feel bad. The material of the wristband is very soft, and the overall wear does not completely feel the weight of the wristband, and no skin allergies have occurred.
My wrists are 17cm long. From the buckle to the first hole 14.5cm, to the last hole 20.5cm, I usually wear in the sixth hole, 18cm, relatively loose, pull up the sensor about 1cm space, but usually All close to the skin. If you wear the fifth hole 17.5cm, it is not too tight, but there will be a feeling to see personal preferences. However, this kind of loose banding method, when the movement of the hand ring, it is also estimated that there is a cause of error in the heart rate measurement. (Mom and eggs, this picture is so tired, one hand is fixed with a soft ruler, and one is holding a mobile phone to take pictures. Everyone looks at the hard work and the gold coin tells me.)
Lifting the wrist light screen is so easy to use. It's totally unpredictable. However, the number of steps, distance and heart rate test switching were a bit crazy. Set the gesture mode, sometimes the wrist will turn several times to success; set the automatic switching mode, to take care of time readings, switching is not too fast. It is suggested that the interval be added in the automatic switching mode in the later period; when the automatic mode is switched to the wrist, double tapping the screen or relying on the gravity sensor, it is recommended to consider adding the finger mode, such as single-finger three-stroke display distance, two-finger single-machine display heart rate and so on.
Talk about the screen display again
A white light oled screen, the display is fairly fine. The normal situation is clear and effortless, as seen in the previous photos. The main criticism is that people are pitted in the outdoors. This is a cloudy outdoor reality. It's not too easy to tell. It's good to block it with your hand, but if it's under the big sun, it's estimated that it's going to work hard. As for the brightening mode of the later upgrade, it is still an egg. The first is always like this, regardless of time and place; the second is the power consumption of the highlighted mode. But if you add a light sensor like a cell phone, one will increase the volume, and the other will not be the current price . Overall, the outdoor display counts as a problem, but it is not a very serious problem .
Since it comes to power consumption, the actual power consumption of this cargo is well controlled. The power consumption is generally about 6-7%/day, and the power is fully charged. It is no problem to support 15 days, and it is still timed to determine the heart rate. Tips, sedentary vibration tips, 3 days of real-time heart rate measurement in one exercise. If you do not run, do not start the real-time heart rate, then the power loss is generally 3 to 4% a day , so manufacturers advertise 20 days of life . For the business trip dog is completely welfare, you can bring one less charger. The charging speed is about 100 minutes, which is nearly 1% charging speed per minute.
The end of the recognition time, enter the following Tucao time
Tucao mainly concentrated in the app. The upgrade is still hard-working. Hand ring to hand prompt new version, and the progress is actually accurate to two decimal places
However, the latest 2.5 version should take note of this precise problem that is not a problem. 
But after the upgrade, restart the bracelet, and then enter the app, or continue to prompt 2.5 upgrade, obsessive-compulsive disorder can not stand
You can look through the history. But all are eyebrows and mustaches, a day of sit-ins, running, etc., for you, not as classified as runtastic. And, besides, when the timetable is called out and left and right slide, it will be automatically positioned on the 1st of the current month and the schedule will be closed. I still need to re-open the timetable, and then choose to view the time, a total of 3 steps, for the Shenma can not be set to open the schedule, let us choose the date? I don't need to look at number 1 every time. Say a good user experience first?
The app's search bracelet is a good idea. But what is shown below is that I carry a mobile phone and put my wrist on my belly. And it is relying on the vibration sound of the hand ring to identify, this sound can not be said very much, it is hard to find something covered by something. It is also suggested that the manufacturers should look for mobile phone functions under the reverse thinking, and that the cell phone has a loud horn sound, and the second hand is always on hand, and all of them are charged. However, the mobile phone can not always find this situation more often, and thirdly, a bracelet less than 200, lost more than a lot of meat hurts, mobile phones, at least thousands, lost meat hurts, if it is fruit, but also back pain . However, this vibrating alert is indeed very comfortable and gentle and not irritating, just as someone gently strokes the back of the hand. However, it is recommended to add vibration strength control later.
Referring to customer service, this is also a pit. No hotline phone even if, but no website online customer service, customer service is actually WeChat exchange . I would like to ask, is the phone typing fast or computer keyboard typing fast? Or take it for granted that WeChat is very good, very fashionable, and very mobile. Either the number of customer service is insufficient, or the number of consultations is too large. If it is the telephone, the investment is large, and the online customer service is too busy. We have slow mobile phone codewords, and the number of WeChat exchanges is more than a phone number and online. I'm more inclined to believe this latter kind of internet thinking, because a normal product manager should know that communication is better for customers
However, the most inconvenient, but also have to force Tucao is step counting consistency and accuracy . Before using the bracelet, the number of steps in the mobile phone is consistent with that of WeChat. However, since the use of the bracelet, three flowers have been blossomed and each one has been shown. There is one more flower than the two flowers of Dan Tianfang. Everyone knows the following screenshots. WeChat customer service, chicken and duck talk for a long time, and customer service said to keep refreshing app, but it is not even a single egg, reload the app and eggs. The attitude of customer service is also good, saying that the next version is correct, but this 2.5 is still the same. Really suspect that this customer service is the incompatibility of competitors
Tucao is complete, sum up time. Overall, this bracelet is a good value for money, has my favorite features, outstanding advantages and disadvantages, out of 100, can 70.
The advantages are, for example, good heart rate accuracy, automatic recognition of the sport mode, comfortable wearing, and long enough life;
However, minor bugs or changes in user experience need to be further modified, such as the accuracy of the number of steps, display switching, customer service consulting channels, and app links such as runtastic.
I sincerely hope that manufacturers will be able to calm down and truly think of Internet thinking to design products, rather than thinking of rapid iterations or using Internet thinking in other places. Because losing a customer in the previous period meant losing a piece of forest. No matter how fast iteratively launched a good product in the later period, after all, the pre-word of mouth was there.
Finally thank you for the polar H7 company in recent years, although it has been sweat, salt erosion is not a good example, at the end of 14 more than 40 US knife to start, fast 2 years, and a battery actually 9 percent electricity
