With the social progress and the accelerated pace of life, how can we accurately know whether our daily exercise meets the health needs? The continuous attention to physical health has led to the rapid development of bracelet products in the past two years, and the functions of bracelet products are increasingly enriched, Handband products with relatively single functions, such as Xiaomi bracelet, can no longer meet the needs of players. The bracelet products with rich content display are attracting more and more attention. With the continuous enrichment of bracelet functions, bracelet products tend to develop in the direction of smart watches. More and more cross-border products enable us to enjoy the pleasure brought by scientific and technological progress. In addition to the basic bracelet movement data record, this product that I experience today also has rich functions such as calling, SMS reminder, real-time heart rate monitoring, WeChat push, etc., to protect our daily healthy sports.

The i7 smart bracelet is packed in a rectangular paper box. The front design of the package is very simple. The logo of the product is printed only in the middle. At the bottom of the package are the basic information of the manufacturer and the QR code of the product APP download, which can be very convenient to download the product APP.

In terms of inner packaging, in order to ensure the safety of the transportation process, the design of hard sponge is adopted, which can protect the smart bracelet reliably. The overall design style is very simple. The user manual of the product is too simple, which may be a little simple for novices.

This time, the author experienced the black version. According to the official website, we can see that there are many colors for users to choose from, which can meet the color selection needs of male and female users.

The smart bracelet is fixed in the form of buckle. The author's actual experience shows that the metal buckle can play a good role in fixing and is not easy to fall off. At the same time, in order to facilitate the user to wear according to the wrist, nine fixing holes are reserved for the watch strap. The wrist strap is made of TPU medical grade material, which is common in smart bracelet products at present.

Aviva i7 provides real-time heart rate monitoring function, and uses the world's top AMS dynamic heart rate sensor to achieve real-time heart rate monitoring function. Of course, if the real-time heart rate monitoring function is enabled, the power consumption is relatively large. In order to achieve good monitoring of heart rate, Evian i7 slightly highlights the design of heart rate sensor, which can better fit on the wrist. Compared with the flat design, this design should have a better effect on heart rate monitoring.

The design of the wrist strap adopts the standard interface design, which is very convenient to replace the standard watch strap. The replacement of the wrist strap is very simple.

For the convenience of users, the most popular magnetic charging mode is adopted for the charging of the i7. The advantage of this charging mode is that it is very convenient to realize contact charging. At the same time, due to the magnetic attraction, when the user places the charging direction in the wrong direction, it will be repelled. It is very convenient and safe to use.

The Evian i7 adopts a 316L all metal body with a body size of 39 * 31 * 8.4mm. The body thickness and appearance size can fully meet the needs of men and women. It can be said that it is located at the balance point of men and women's wear, which will not make women feel too big, and men will not feel too small when wearing it. Although the whole metal body is used, the weight of the bracelet is only 30g, which can be ignored in daily wear.

In addition to ultra-low power consumption, the most important thing of this type of display is the display effect. The display effect under the sun is perfect.

The i7 adopts the design of capacitive touch screen, and the author found that the design of the touch screen needs further optimization. The protective glass of the bracelet uses the 2.5D ultra-high reinforced glass, which is the most popular in mobile phone design at present. Because of the 2.5D design, the corners of the Evi7 are more smooth, and the edges of the protective glass will not feel like cutting hands. It is very comfortable to feel.

In terms of standby, the bracelet is equipped with a 100mAh polymer lithium ion battery. Through the author's practical experience, when the real-time heart rate monitoring function is turned on, the standby time is about six days, which is basically consistent with the official description. According to official data, when the real-time heart rate is turned off, the standby time can be up to about 20 days, Users can choose whether to turn on the heart rate function according to their own needs.

Since the i7 has a capacitive touch display screen, basic motion data can be displayed through the display screen, including time, motion data, and basic settings for the bracelet. However, more data statistics and data analysis still need to be achieved through APP. The i7 supports Android 4.3 and iOS9 and above systems, and is connected to mobile phones through Bluetooth 4.0 technology. The effective connection distance is about 10 meters.

The author's mobile phone is Android system, so the APP involved in this article is Android version. In addition to the function of mobile phone or email registration, WeChat i7 also provides quick login on WeChat and QQ. Since there are so many micro blog users at present, it is suggested that the manufacturer consider adding the function of quick login on micro blog. In addition to the basic height, weight, and gender settings, the i7 is also very convenient to connect, and you can follow the prompts to achieve a fool like connection. APP provides relatively rich function settings, including display time, sleep, gesture, etc. You can choose to use it according to your needs.

As a bracelet product, a very important function is sports statistics. The author is a fat man. The app of Evi7 provides the function of setting the daily exercise amount according to the weight. According to the goal, the daily exercise amount of the author needs to reach more than 10000 steps. In terms of sports statistics, the statistical function of i7 is very detailed, and the amount of sports in each period is recorded in great detail.

In terms of sleep records, due to the author's serious cold and cough recently, the sleep at night is very unsatisfactory, which can also be seen from the statistics of the bracelet. The sleep quality is also divided in detail according to the time period. At the same time, APP gives some suggestions on sleep. In terms of data statistics, Evi7 counts the daily sleep status by week and month, so that users can adjust their work and rest according to their own sleep status.

In addition to the movement function of the bracelet, the i7 also provides the function of recording movement according to GPS, which has certain reference value for users who need to count their own movement routes every day. In terms of real-time heart rate, after heart rate statistics is turned on, heart rate curve will be recorded automatically, and at the same time, movement and activity in each time period will be given. Of course, this heart rate value can be used as a reference value. If accurate heart rate recording is required, it is more reliable to go to the hospital. An important function of the bracelet is the daily reminder function, which mainly includes schedule and alarm clock reminders. The Evian i7 supports six alarm clocks, which can basically meet the daily reminder needs. In terms of schedule reminders, it supports up to four daily reminders, and up to 32 schedule management. It is very good for daily meeting scheduling and appointment reminders.

Because Tencent has opened the QQ health function, many users like to compare their daily exercise with others. Evi7 also supports access to the QQ health ranking and provides daily exercise data to compare with friends. For users who like to take self portraits, the remote control photography function of Evi7 is also very good. When the photography function is turned on in the APP, auto focus will be achieved. By clicking the touch screen of Evi7, the photography function can be achieved, which is very convenient.

In terms of interaction, Evian i7 has added voice function, which can obtain current movement data, weather conditions and other information through voice. APP also provides a relatively professional testing function, which can simply test the physical condition of users.

Thanks to the touch-screen display, the i7 can easily view the relevant data of the movement without a mobile phone. Slightly slide up the touch screen to observe the steps, mileage, calories consumed, real-time heart rate and other information. The step recording statistics of Evian i7 are relatively accurate under the condition of normal walking. The author used 50 step walking tests for each group, 4 groups in total, and the errors were within 3 steps. However, if the arm wearing the bracelet carries the hand bag and walks, the error is relatively large. This should be related to the arm swing counted by step recording.

The i7 can set sports items by touching. Under the corresponding sports items, the statistics of sports data are more accurate. Under the corresponding movement type, long press the touch screen to automatically enter the movement data statistics.

Another very practical function of the touch screen is the push function of messages, etc. At the same time, when the phone is connected, Evi7 will give a reminder, and the corresponding operation can be achieved through touch. In terms of message push, set the information to be pushed as needed, such as SMS, QQ information, WeChat information, etc. The i7 can retain the push display function of the last eight messages.

Apart from the mobile phone APP, the i7 can set some simple functions, such as the replacement of the dial. Unfortunately, there are only three dials to choose from at present. We look forward to the manufacturer's subsequent software development and increase the selection of dial types. Automatic heart rate shutdown, bracelet shutdown and other functions can be set here.

Summary

With the capacitive touch screen, the i7 can display various motion data more conveniently, and can be set conveniently according to user needs. It also has good experience in sports data recording, sleep monitoring, information pushing, etc. It is comfortable to wear, has heart rate monitoring function, and can last about six days under real-time heart rate monitoring. The price of 299 yuan is still worth looking forward to.
