Fitbit Flex is one of the popular health bracelets. Its shape is not as beautiful as JawBone UP, nor is it the heart rate selling point of Withings Plus. It is now a product with good reputation in all aspects. What makes Fitbit Flex so attractive?

Appearance design:

Fitbit Flex is packaged like a watch.

At the bottom of the package is the recording function of Fitbit Fxe, and its wireless synchronization is also a big selling point.

Fitbit Flex's complete set of accessories and body.

Fitbit Flex comes with two size wristbands, which are more optional than Jawbone UP. However, it seems that the wrist strap of Fitbit Flex does not use special materials or processes, and the trace at the mold connection can be clearly seen. The texture is also quite ordinary.

The synchronization receiver of Fitbit Flex is similar to the mouse receiver, which synchronizes via Bluetooth 4.0.

The special charging accessory of Fitbit Flex may be easier to use if it is designed together with the synchronizer.

The body of Fitbit Flex is very compact, which is smaller than most USB flash drives.

The use of Fitbit Flex is quite simple. Select a suitable wrist strap and insert it. However, the wrist strap of Fitbit Flex needs a certain amount of force to buckle down, and carelessness will cause considerable pain.

Fitbit Flex does not have any buttons. It provides interactive feedback by tapping. There are five lights on the front of Fitbit Flex to express the percentage of goal completion. Click Fitbit Flex twice to give the percentage of target completion to light up. If 10000 steps are taken as the target, 3 lights will light up when 3000 steps are completed. Tap Fitbit Flex several times to enter sleep mode and record your sleep status.

Fitbit Flex also makes a strange judgment on knocking. When I take a quilt and pillow, I sometimes recognize it as knocking, but when I lie in bed, I can't recognize how to knock to enter the sleep mode.

App synchronization experience:

The synchronization of Fitbit Flex is quite fast and powerful, and its synchronization is different between PC and mobile phone. After installing the corresponding App, you can synchronize.

After installing the corresponding App on the PC, you can see that the interface is quite simple.

The synchronization of Fitbit Flex is very fast, and the synchronization process can be completed in a few seconds. However, this ontology app is only used for synchronization. To view relevant data, you need to log on its official website.

It is easier to synchronize Fitbit Flex with your phone, but you need to confirm that Bluetooth 4.0 is used first. At the same time, it can also automatically enable the corresponding App automatic synchronization through NFC pairing, which is quite powerful.

In addition to its very fast synchronization speed, Fitbit Flex's most powerful feature is its real-time synchronization feedback after synchronous connection. After synchronization and connection, your data will always be synchronized during your movement.

App experience:

The app design of Fitbit Flex is in line with the rules, and there are not many highlights. It displays the percentage of goals completed through bars, and can view the corresponding time. At the same time, it can also set corresponding goals, alarm clock and other functions. In general, there should be, but without a Chinese interface, some users may be rejected.

App can see the completion of the set goal, which is represented by the progress bar.

Enter the corresponding sub item to view the corresponding data arranged according to the time, as shown in the figure, the left is the steps of the morning work time; The right side shows the corresponding situation during sleep.

Q&A：

Q: Is Fitbit Flex waterproof?

A: Officially, Gitbit Flex is waterproof and can be worn while swimming. In contrast, Jawbone UP official said that it is not recommended to wear it when swimming.

Q: What should we pay attention to when synchronizing Fitbit Flex?

A: Synchronization of Fitbit Flex with mobile phone requires mobile phone Bluetooth version 4.0. In addition, some manufacturers have compatibility problems. For example, although the HTC Butterfly S in my hand is Bluetooth 4.0, there is a problem with its compatibility, so it cannot be synchronized. At present, the best ones are Apple iPhone series and Samsung Galaxy series.

Q: Does Fitbit Flex have an alarm clock?

A: Fitbit Flex has an alarm clock to remind you, but it does not have the intelligent alarm clock of Jawbone UP, and there is no gap alarm clock. To complain, the alarm clock of Fitbit Flex is very annoying. Its vibration is long. At the same time, it is weird to knock the provisional judgment. Every day, I get up with complaints.

Q: Is Fitbit Flex durable?

A: At present, I believe that the Fitbit Flex is quite durable. Its body is just a small U-disk, and it is also installed in the small compartment on the wrist strap, making it quite protective. In contrast, my Jawbone UP has fallen off parts and yellowed materials.

Q: How about the endurance of Fitbit Flex?

A: Officially, the battery life of Fitbit Flex is 10 days, but I was told that the battery was low after one week or seven days of use. It should be noted that after the first synchronization of Fitbit Flex, it will send an email reminder when the target is completed and the power is low, which is quite interesting.

Q: How is the Fitbit Flex experience?

A: In my experience of more than a week, the biggest highlight of Fitbit Flex is its very fast synchronization. Compared with Jawbone UP, it needs to be taken down for synchronization. With Pulse, long press for 3 seconds for synchronization. Fitbit Flex has automatic synchronization, which makes the experience quite refreshing. However, compared with Jawbone UP, it lacks an intelligent alarm clock, which makes people feel angry every day.

Summary:

In general, Fitbit Flex is a standard product in terms of functions. Its basic recording functions, such as steps and sleep, are essential in today's health equipment, and there is not much outstanding. However, compared with other health devices, Fitbit Flex is relatively inexpensive, and it is outstanding in some details, such as wear and waterproof level.

The biggest selling point of Fitbit Flex is its powerful synchronization function, which can be said to be the most powerful among similar products. However, it has some compatibility problems, which affects the experience to a certain extent. Fitbit Flex is also very easy to use. It feels good to complete feedback by tapping.
