Fitbit was founded in 2007 and is headquartered in San Francisco, USA. At that time, the two founders realized that the development of sensor technology and wireless technology provided new experiences for people's sports and healthy life, so they established Fitbit. Their first product is a pedometer called Fitbit Ultra, which can transmit the recorded and tracked data to the computer through wireless technology. Later, they introduced Aria, which can transmit data indefinitely. Now their main products are Fitbit One with sleep recording function and entry-level Fitbit Zip. Their latest product caters to. Wearable computing? The trend of smart bracelet Fitbit Flex.
On Fitbit's homepage in official website, we can see that their current product family, Fitbit Flex, has attracted much attention since its release. After learning about this product in March this year, a merchant ordered one on Taobao. At that time, Fitbit officially announced that it would start shipping in early May. After a series of official jumps, I really got the Fitbit Flex bracelet in mid-July, and at this time I have actually used Jawbone UP for two months. But it's better this way. I can introduce this Fitbit Flex smart bracelet to you from a comparative perspective. (Jawbone UP, please refer to the brother website? Love geeks? about

But I don't agree with them about the smart bracelet? Install 13? Definition, as to why I will explain later in the article. First of all, the packaging of Fitbit Flex smart bracelet is relatively simple, including:
● Flexible tracker
● A wrist strap and a wrist strap.
● A wireless transmission receiver.
● Dedicated charging cable.
● Quality assurance certificate.
● Free membership in Fitbit.com (non-physical)
●iPhone or Android applications (non-physical, self-downloaded)
Fitbit Flex is not so much a smart bracelet as a health tracker worn on your hand. Its real body is just two little finger-sized trackers, which complete all the tracking/recording work. When in use, put the tracker into a special wristband and wear it. Flex can mainly track and monitor your daily life: walking steps, walking distance, calorie consumption, activity time, sleep duration and sleep quality.
Very compact flexible tracker with flat surface, rounded corners and straight lines.
Flex tracker is so small, compared with USB port of charging cable.
Although this health tracker is small, it has everything. Flex has built-in lithium-ion battery and its charging module, MEMS 3-axis acceleration sensor, Bluetooth 4.0 module, memory module, vibration motor and five LED lights. The external interface of the whole sensor has only three charging contacts at the bottom. Everything is actually done by finger tapping, which is very interesting. We will explain it in detail later. In addition, the authenticity of our own state is displayed by the combination of five white LED lights.
When charging, five LED lights will light up gradually, and each light represents 20% of the power reserve.
Officials claim that Flex can support applications for about 5 days, and it is recommended to charge it every 3 to 5 days. I started using it on Tuesday, and there are 2 batteries on Sunday (5 batteries when fully charged). Maybe I don't exercise much, so I always consume less. When charging, take the tracker out of the wristband, put it into the special charging cable slot, and then plug in the USB interface to charge.
It's conscience to wear two wristbands. If the large size is not suitable, you can also apply for XL code from the official.
Fitbit Flex directly provides two wristbands, one large and one small, in the packaging. Users can choose according to their own needs, which is very kind, unlike Jawbone UP, which is only suitable for a single size.
After choosing the size, insert the Flex tracker into the wristband, and you can see the metal contacts on your ass.
You can clearly see the arrow mark on Flex tracker. Please install in this position.
In fact, it seems nothing, but it can be more flexible in practical use, which I deeply understand: it's only summer, and I'm a sweaty person. If I stick Jawbone UP medium tightly on my wrist, I will sweat a lot at the place where I contact with my skin, and the taste here will be very bad after a long time. Using Fitbit Flex large wristband, the buckle is a little loose, and there is a certain distance between the skin and the wristband, which is convenient for air circulation, so there is no such trouble. In addition, the position of the arm can be adjusted according to the tightness of the wristband, such as in the front or back of the watch. The fixed-size jawbone UP can only be placed in front of the wrist.
The actual effect and shape of getting started are still very ordinary, and no one will notice when walking in the street.
This button is designed to be a little tight, so it needs to be pressed hard, and sometimes it will hurt your arm.
There is a transparent material area on the wristband, which just allows the LED light of the Flex tracker to come out.
At present, Fitbit only offers two colors to choose from when purchasing: black and slate cyan. In addition, they have a set of wristbands in three colors (orange, navy blue and aquamarine), which are sold separately as accessories. Among them, three wristbands are packaged and sold together, and official website quoted $29.95.

By the way, Fitbit Flex has a split structure and is not waterproof, so before taking a bath or swimming, you must remove the handle ring to avoid short circuit caused by contact with water.
The wireless transmission receiver attached to the package occupies a USB port, which is a bit inconvenient.
The biggest advantage of Fitbit Flex smart wristband hardware is that it can transmit recorded data wirelessly, which can not only synchronize data with the computer, but also support wireless synchronization of data directly to the mobile phone. Fitbit Flex is better than Jawbone UP in this respect, and Jawbone UP cannot synchronize wirelessly. However, Flex uses Bluetooth 4.0 technology, so it can only support some iOS devices and Android devices, mainly Apple products after iPhone 4S and some newer Samsung Android phones. See for details.

. This is the case with the basic hardware of Fitbit Flex. Let's talk about software and usage first. It is the first time to use Flex. Follow the instructions on the package and have a look first.

, and then download the Flex dedicated connection software (Windows and Mac OS versions respectively) according to the prompts, then plug in the wireless receiver contained in the Flex package on the computer, and then register an account according to the prompts of the software, fill in the information, and you can officially start using Fitbit Flex. Of course, this process can also be completed directly through the APP. Fitbit Flex？ Smart bracelet wireless exercise sleep recording wristband

Unfortunately, Fitbit doesn't seem to pay much attention to the China market. Not only does the website/software not provide the Chinese version, but even the iOS APP can only be downloaded from the American APP Store, which is not searchable in the China APP Store, so if you don't have an American APP Store account, you can either register one (the method is visible).

), or just synchronize with the computer. In this respect, it lags far behind its direct competitor Jawbone UP. After all the settings are completed, you can start to use the Fitbit Flex bracelet (it is recommended to fully charge the Flex before using it for the first time, so as to avoid the novelty when using it at first, and then conduct various tests to quickly charge it). The first step in using it is of course to put Flex on your wrist. Fitbit's official suggestion is to wear it on your unprofessional hand (if you are right-handed, your left hand is your unprofessional hand, and your left hand is your right hand), which can further reduce the recording error. Here, I still want to spit out the buckle of the Flex bracelet. Maybe Fitbit wants to make the clasp of the bracelet stronger and firmer, so the clasp is designed very tightly. It takes a lot of force to close it when you wear it. It is easy to hurt your wrist.
The personal center of Fitbit computer website displays the data transmitted by Flex. Put on the Chinese interface and you can leave it alone. At this point, the Flex bracelet has entered the tracking and recording state, which will record your daily walking. As long as you are within 10 meters of the computer with the wireless transmitter installed, Flex will automatically connect and synchronize the data to the official online database of Fitbit, or automatically synchronize when you open the Fitbit APP in your mobile phone. You can visit Fitbit official website at any time, or you can access these data synchronously through the mobile APP.
In addition to viewing your walking data on official website and APP, you can also tap twice directly on the front of Flex. At this time, the LED light on Flex will light up, showing the proportion of the target steps you took that day. The target number of steps was also set at the beginning. For example, if you set 10000 steps today, then each LED of Flex represents 10000 1/5, which is 2000 steps. If you see that two LED lights are on all the time and the third LED light is flashing, it means that you have walked more than 4,000 steps now and haven't reached 6,000. Once you reach the target number of steps for the day, Flex will start to vibrate rhythmically and make five LED lights flash to celebrate your achievements. This design is very interesting, mainly to further stimulate your competitiveness and let yourself go more ways to complete the goal setting. In contrast, Jawbone UP does not have such a target incentive method.
It doesn't need much force to knock on this place, and this inductive operation mode using acceleration sensor is very convenient.
After working for a long time, I don't think most people have the habit of exercising regularly every day. I'm afraid the most exercise they do every day is walking. Fitbit Flex lets users know about daily activities through recorded walking data, and encourages users to walk more and consume more calories through some incentives. For office workers who find it difficult to spare special time for exercise every day, this method is obviously a more acceptable fitness concept.
In addition to recording your exercise, Fitbit Flex can also monitor your sleep. It is also very simple to use. Tap the front of the bracelet with your finger 1 to 2 seconds before going to bed. After seeing five LED lights flashing, the leftmost and rightmost LED lights stay on for two seconds, indicating that Flex has entered the sleep monitoring state, and then you can have a good sleep. After getting up in the morning, still tap the front of the bracelet with your finger 1 to 2 seconds. After the left and right LEDs are always on and five of them are flashing together, Flex ends the sleep monitoring state and switches back to the daily tracking mode. At this time, if you synchronize Flex, you can see your sleep last night on the computer or in the APP.
Borrowing a picture from official website, tracking and recording sleep quality is a very popular health behavior in Europe and America.
What are the sleeping conditions recorded by Fitbit Flex? Sleep? (normal sleep)? Restless? (light sleep),? Are you awake? (awake) three States. At present, normal sleep and waking state are well understood, light sleep, according to the explanation in the interactive encyclopedia:? People's sleep is rhythmic, and deep sleep and shallow sleep are repeated alternately until they are awake. Shallow sleep refers to the stage between waking and falling asleep. ? In other words, light sleep is what we often say when we sleep? Dazed? The state of. In addition, Fitbit Flex can also tell users when they started to sleep, how long it took them to fall asleep and how many times they woke up. Can users adjust their sleep habits according to these data, such as playing some before going to bed? White noise? Or? Ambient sound? Improve your sleep speed and deep sleep duration.
Monitoring sleep depth is actually? Sleep management? Part of it is that managing sleep is necessary for busy office workers. A good sleep determines the state of your day. In fact, there are many APP applications on mobile phones that can be used for sleep monitoring. However, due to the limitation of hardware, the accuracy and convenience of sleep monitoring applications on these mobile phones are far less than those of special wearable devices. Therefore, if you always feel that you are short of sleep, or sleep lightly and easily wake up, it is still necessary to monitor your sleep and then deal with it.
I slept on Monday. I fell asleep in about 5 minutes, but I slept soundly afterwards.
I fell asleep quickly on Tuesday, but I often took a light sleep after 4: 30. Appendix: white noise software recommendation: you can search Relax Melodies Oriental in apple APP Store, which is a series of very oriental environmental sounds. I personally recommend it? What about Tian? +? Meditation bowl? A combination of sound effects.

》; And Zhihu's question and answer, "How do shallow sleepers improve their sleep quality?
In addition to tracking steps and monitoring sleep, Fitbit Flex smart bracelet also has a very useful function, which is silent alarm. In fact, it is a vibration alarm. Set an alarm clock in Fitbit website or application, and Flex will remind you by vibration until you tap the front of the wristband with your finger. In fact, the vibration alarm function may be the most popular function of smart bracelets such as Fitbit Flex, which is true from my personal experience.
Fitbit's personal homepage can set mute alarm. I am divided into two groups according to working days and rest days.
For example, I used to get up at 6 o'clock every morning and leave early, while my wife got up at 6: 40. My daughter-in-law's cell phone alarm at 5: 50 to 6: 00 used to wake up, and it didn't work well, so you know the situation. But it's okay now. The vibration of my wrist at 5: 50 will wake me up, but it won't affect my wife. In this way, my home is much more harmonious in the morning. There are many similar occasions in daily life. I hope to have an alarm clock that doesn't disturb others, or in situations where I can't hear the ringtone of my mobile phone because of too much noise. The smart bracelet worn on your wrist will never let you miss the reminder.
These are the functions of the Fitbit Flex wristband itself. In fact, Flex wristbands can have more ways to play their official website and mobile APP applications, such as recording daily diet; According to the calories burned by daily exercise, give your dietary guidelines; Data link with Fitbaria wireless weighing scale; There is even a senior member function with an annual fee of $49.95 (giving you professional weight loss/fitness/exercise planning and guidance); Unfortunately, due to the lack of Chinese support and local food database, these extra functions are basically unavailable (of course, if you are proficient in English and only eat western food, you can challenge it).
Fitbit's personal home page records the diet page, but unfortunately its food database only supports English.
Ok, now let's talk about Fitbit Flex's recording error. Fitbit Flex is relatively accurate for sleep monitoring. It took me a week to record my sleep time, which is basically the same as putting Jawbone on while sleeping. Personally, I think there is no mistake in this respect. And I also pay more attention to the error of step recording. After all, the walking distance and calorie consumption tracked by Fitbit Flex are calculated according to the walking steps and height and weight in your personal data. So the number of walking steps is a very important variable in daily exercise data, so the accuracy of walking steps is very important.
In this respect, Fitbit Flex tends to record more steps than it actually does. I have measured the error of the jawbone before. I walk 500 steps by myself, and UP will record that I walk about 570 steps. Testing Fitbit Flex under the same conditions and methods, 500 steps will record that I have taken about 590 steps. I also wore two wristbands one day. Jawbone UP records that I walked about 12800 steps, and Fitbit Flex records that I walked about 14000 steps.
? Fitbit Flex recorded exactly 100 steps before and after driving 14 km.
In addition, I also tested how many steps my wristband recorded by mistake while driving, and the result was a bit unexpected. At the same time, after driving 14 km with the same wrist, Jawbone UP thinks I took 104 step, and Fitbit Flex thinks I took104 step. In the case of relatively small range of motion, the gap between the two seems to be relatively small. To sum up, basically Jawbone UP's record data needs 8.8 fold, and Flex needs 8.5 fold. It seems that no matter how the manufacturer improves the algorithm and technology, the error is inevitable.
Despite this regret, I strongly recommend this Fitbit Flex smart bracelet product, especially for those editors/staff/programmers who have worked as long as me!
Why? These years? Karoshi? News came one after another, but sub-health is normal among sedentary office workers. Just two days ago, it was reported that a colleague of mine who was under 35 years old died of health problems. This fact always makes people realize that the crisis is not far away from them, and always makes them make up their minds to strengthen exercise and pay attention to diet, but these plans are put on hold because of various problems in real life. In fact, what we need is not necessarily high-intensity and long-term exercise every day. Sometimes, as long as you can walk two more stops every day and sleep for an hour, you can get your health to a higher level. All you need is a little encouragement and support. Smart bracelets like Fitbit Flex can help you do this.

Maybe you are still young, about 20 years old, and you have more sports meetings. Maybe you don't agree with what I said above, and even think that buying this thing is a fashionable behavior of 13. But at the age of 30, my working life is getting busier and busier, and my time is getting less and less. When you want to find a large amount of time to exercise, but you can't do it, maybe you can understand the true value of this product.
In addition, don't tell me that there are applications that can complete these functions on the mobile phone, so why buy a smart bracelet? First, most of these functions are completed by separate APP applications and service providers, making it difficult to achieve seamless docking; On the other hand, many times the mobile phone is not around, such as when sleeping, having a meeting or walking. At present, only wearable devices such as Fitibit Flex smart bracelet can follow you all the time, track and record your life/health around the clock, and seamlessly complete various functions.
Buy a smart bracelet like Fitbit Flex, right? Keep up with the fashion and wear equipment Or? Improve your b-grid? So there is no nutrition, which is actually an investment in one's health and a responsibility for one's body. The bracelet can be used almost 365 days a year. Even if it only takes one year, the converted cost is equivalent to taking the subway twice a day. So I strongly recommend buying a smart bracelet.
As for which to buy, Fitbit Flex and Jawbone UP, I personally like it. I've been using Jawbone UP for over two months, and Fitbit Flex only took a little over a week. Based on my personal point of view, I made the following simple summary, hoping to help you choose to buy:
● What are the advantages and disadvantages of ●Fitbit Flex compared with Jawbone UP?
1.？ Please refer to the previous article, Flex can be resized, and UP has a fixed size. In addition, the fixing method is Flex, which is more firm, and you don't have to be afraid of being squeezed out when squeezing.
2.？ There are different opinions on the appearance. Personally, UP pays more attention to design, while Flex is slightly low-key and involves moderate ideas.
3.？ Flex is not waterproof, UP can live waterproof (but don't take it to take a shower. Many cases on the internet show that taking a bath for a long time can also lead to the water cut-off of UP.
4.？ Flex official website and APP applications do not support Chinese, and APP can only be downloaded in the US APP Store; UP's official website and application support Chinese, and the application can also be downloaded from stores in China.
5.？ Flex can directly display the completion of walking goals on the bracelet, which is better than UP in encouraging users to exercise more. I once deliberately got off the subway two stops early to go home in order to achieve the goal of all five LED lights (obsessive-compulsive disorder, you know).
6.？ Fitbit Flex's killer is wireless synchronization, which Jawbone UP can't achieve. My own experience is that every time I synchronize Jawbone UP, I feel very troublesome, because I have to take it off my hand, remove the cap of the interface, and then plug it into the earphone hole of iPhone. Is this exactly the same as the process? Elegant? You can't touch it. Be careful not to lose that little hat. You can search on Yi Bei and Taobao to see how many businesses sell that little hat, and you will know how many people will lose it. Therefore, the wireless transmission function of Flex greatly wins.
7.？ Flex has no idle reminder function, while UP can be set at a certain time (such as office hours), and every once in a while (such as 1 hour), there will be vibration to remind users. This function is very beneficial for sedentary work. It can remind you to stand up and relax every hour. I think Flex needs to supplement this function most, and I hope it can be realized by upgrading the firmware.
● Should I buy Fitbit Flex or Jawbone UP?
Generally speaking, Fitbit Flex has a high degree of hardware completion, but it lacks some software. On the one hand, it doesn't support Chinese, on the other hand, websites and apps are slightly more complicated and have higher requirements for users. Jawbone UP has many shortcomings in hardware, but the software supports Chinese and is easier to use. Generally speaking, it is good to buy any kind of diamond cut diamond, but I think the main determinants are as follows:
1, depending on your English level, you can choose Fitbit Flex if you have confidence in English, and Jawbone UP if you are struggling with English.
2, look at your preferences for appearance, like low-key man show to choose Fitbit Flex, choose Jawbone UP, if you like to design concave shapes;
3. See if you are afraid of trouble. If you are afraid of trouble, choose Fitbit Flex. Wireless synchronization is very convenient. If you are not afraid of trouble, choose Jawbone UP and plug in your mobile phone every time.
At present, although Fitbit Flex has been listed, it is still in short supply in the market because of the problem of production capacity. The official Fitbit Mall even marked the prompt that it will not be delivered until 8 weeks after placing an order. Coincidentally, Jawbone UP is also out of stock worldwide, and its official sales channels such as Yixun.com and Apple official website are basically out of stock.
