# original innovator # one-time three-ring is å•¥ feeling? bong2s, bong3, millet bracelet 2
Recently found that a little overweight, usually still a little less athletic opportunities, so I intend to start a bracelet to see how much exercise.
With reference to Ama's various evaluation data, the primary needs were identified: step count, and battery life, heart rate/time display, etc., with additional bonus points, locked a few: bong2s, bong3, millet bracelet 2, bong2 tangled in special-shaped batteries, And there is no new goods, misfit shine2 is also considered, but the price is still high (jd activity price also 299).

Misfit Shine2 Apple ios Android Smart Footsteps Sleep Sports Bracelet Health Watch Runner 699 yuan Lynx Featured Direct link The final result is through different channels to start with bong2, bong2s, shine2, a total of no more than 200.
To hand-battery/charging time: Bong2, 3.29 battery is used synchronously from official purchase to hand-on, Bong 2s, 3.27 to hand charge for 2 hours full sync with APP to start using, Shine2, 3.27 to hand-held battery (Shopping center 5RMB to buy Panasonic Batteries) Synchronized APP started to use.
There are a lot of unpacking quotes, and I will not post more drawings. I just provide a three-handed bracelet that I wear at the same time:
The reasons for the order: When watching wear requirements, notice that the bong2s that can detect the heart rate require to wear it at a specific position. However, if the goose is not well fixed, too tight or too loose, use Shine2 to block it. As for bong2 and shine2 Did not pay attention, casually wear.
Fortunately, bong2 and bong2s are different APPs, otherwise there is really no way to test at the same time.
In the vicinity of 10 days (running time.....?), an accuracy test was carried out while hand-held glory X2 X-ray exercise readings for comparison, for reference only, the results are as follows:
First provide the readings before the test:
The first one: to leave the hand test, sitting on a stool, wearing three bracelets hands drooping hand 200 groups (for the pimple is 200 groups, I think), shine2 record 400, bong2s record 92, bong2 record 179, mobile reading 400 , as shown:
In the second item, normally walk 200 steps, and the hand wearing the wristband swings normally. The readings are as follows: shine2,180, bong2s,97, bong2,218, mobile phone, 284, as shown in the figure:
The third item, pretend to play with a mobile phone, take 200 steps, and wear a mobile phone with a bracelet. The reading is as follows: shine2,208, bong2s,160, bong2,203, mobile phone, 198, as shown in the figure:
From the test results, shine2 has the highest accuracy, bong2 follows closely, bong2s does not work, and the cell phone records also have certain deviations. However, gooses are not unacceptable. Whether the three bracelets wear together will affect each other and can only be said to be impossible. avoided.
As for sleep detection, all three bracelets are available, but the Goose has only reference value, and there is no more data;
The three bracelet algorithms all record the stationary hand movements, but the movement of the goose and the stationary arm can also be recorded normally. Then, can we work hard on the algorithm to block off the hand movement? Or the simple hand movement is also an effective movement. Did not expect =.=
Take a look at the use of this time:
Bong2: Advantages: 1. The pedometer accuracy is relatively high, as can be seen from the test; 2. The battery is durable, with half a month, the display is sufficient; 3. There is an egg pain time display function; 4. The Yes key has an expansion Sex, then goose can not see now use; 5. Sleep helper gives sleep advice to a certain extent, you can refer.
Disadvantages: 1. Special-shaped battery compatibility = 0, can only find the official purchase; 2. APP network dependence is too high, in the absence of the network even if the synchronization is successful, the data can not be displayed (try once, exit and reopen APP Still not shown), features such as details/expanding are even more unusable; 3. Synchronization performance needs to be improved (if it still improves), synchronization is now required to ensure a certain success rate in a fixed position.
Bong2s: Advantages: 1. The battery is still good, set the smart detection of heart rate in the case of 20 days is not a problem; 2. synchronization success rate is much higher than the bong2; 3. heart rate detection, try, take their own pulse count, the gap is okay , but this needs to be worn tightly only to have effect, began to wear a period of time there is a record, but later there is no, rather strange; 4. APP on the network to reduce some of the sports details can be viewed offline.
Test the day of electricity display as shown:
Disadvantages: 1. The step count accuracy is bad; 2. The data report is not displayed in the non-networked state; 3. There is no other output function from the APP; 4. The charger is unique.
Shine2: Advantages: 1. The step accuracy is the highest among the three; 2. The battery is universal and durable, but the APP display does not seem to be reliable, but the goose is not a problem for one month; 3. The time display is not bad, but the goose will not appear. Accurate situation; 4. There is a link APP can extend the function, even if Android is also able to achieve Bluetooth photo =. = 5. APP can be used off the net; 6. can be worn in different locations for different sports count, but the goose does not Tested.
On the test day, the electricity is shown in the figure, but the goose is now full again:
Disadvantages: 1.APP is larger than bong; 2. No details; 3. Time display is ugly outdoors; 4. Expensive.
Waterproof performance, no special test, daily use should be no problem.
Ring belt, feeling or shine2 is better than bong's.
Just learned from a friend that the fitbit bracelet does not record the number of hands
Finish.
