* Preface *

In a report "2014-2015 Intelligent Hardware Market Analysis Report" issued by Speedway Research Institute in 2015, it was pointed out that 2015 is a year of rapid development in the field of intelligent hardware, and intelligent wearable devices will set off a new wave in the electronic consumer industry. In addition to foreign well-known brands such as Apple and Samsung, domestic enterprises such as Huawei, Xiaomi, Evei, Jiaming and Gudong are also unwilling to lag behind and have launched their own brands. At the end of last year, the annual sales of Xiaomi bracelets exceeded 10 million The market competition for smart bracelets is so fierce that it is really a problem how to stand out from many bracelets. Maybe only continuous innovation is the solution.

＊ iwown i7 intelligent heart rate bracelet ＊

Today, I want to introduce the 2015 flagship product of Evey, the iwown Evey i7 Intelligent Heart Rate Sports Band, launched by Shenzhen Evey Information Technology Co., Ltd., which is a healthy band focusing on heart rate. The company is mainly positioned to provide complete mobile Internet software and hardware products, and has launched the i5 bracelet and i5plus bracelet. These two bracelets are also the classic works of the company, ranking top in the sales of JD. As the flagship product of Evo in 2015, what surprises are there in the i7 heart rate bracelet? Let's have a few photos to satisfy our eyes.

▲ Micro i7 looks like a watch.

＊ Details of Evian i7 bracelet ＊

Take a closer look at the Ivy i7 bracelet.

▲ When the bracelet was just taken out, it was not particularly amazing. The black color was very low-key. Pan Xiansen said it looked a bit like a digital watch. The dial adopts a square design, which looks more like a smart watch. The front of the dial is made of 2.5D ultra-high reinforced glass. I checked Baidu Encyclopedia. According to the introduction, The 2.5D glass screen has a flat area in the center of the glass, and then radians are processed on the edge based on the flat glass. Many mobile phones use such glass, which can It is to improve the overall visual effect of the screen and the body, improve the feel, and more ergonomic. I felt it, clock dial It does not feel good wrong.

▲ When the watch is just taken out, there is a soft film on the dial surface, which can be torn off for use.

▲ The default display interface has time, date and day of the week for easy viewing.

▲ If the dial is worn for a long time, it is easy to be stained with dust or fingerprints, which can be wiped off with paper. However, the scratch resistance of the dial is good. After wearing it for several days, I didn't see any scratch marks.

▲ The back of the dial is the heart rate sensor and charging interface. When measuring the heart rate, the middle sensor will emit green light. As you can see, the watchband is also prone to dust.

▲ The wrist strap is made of TPU medical grade material, which has the characteristics of high tension, toughness, high wear resistance, aging resistance, oil resistance, water resistance, mold resistance, etc. It is a mature environmental protection material, and it is also very skin friendly and comfortable to wear.

▲ Wrist belt buckle, I feel that this watch belt buckle is not particularly easy to use, and it can be fixed only by pressing hard.

▲ There are 8 holes in total, and the changeable length of the wrist strap is from 16.8 cm to 21.8 cm, which can be worn by both men and women.

＊ WeChat Health Assistant APP ＊

The supporting app of Evey bracelet was called Zero One, and later it was changed to Evey Health Assistant, which can scan the QR code on the manual to download the iOS version and Android version.

▲ The launch page introduces the main functions, including health data, voice chat, and personal exercise plan.

▲ For the first use, you must first register with your mobile phone and set gender and basic information. The above figure is the default display information, which you want to change, mainly height, weight, birthday, physical condition and work type. These information can be changed in the APP after it is not written in the registration. After registration, the login interface will pop up automatically, and enter the password to log in. Of course, you can also choose WeChat or QQ to log in.

1. Three interfaces of APP

▲ APP has three interfaces, namely: Home, Voice, and My interface. The picture above is the homepage, which has just been registered, but no information has been added yet. The top of the home page is used to connect the bracelet. The middle shows today's health and score. The left villain will use color to show how much energy there is. At the bottom, you can set your own exercise goals, daily target steps, yesterday's sleep, alarm clock, target weight, and heart rate. Click the plus sign at the bottom of the home page to add or hide modules on the home page, including exercise, sleep, schedule, weight, and heart rate. The default is full display.

▲ This is the second largest interface. Click the microphone icon next to the home page to chat with the voice assistant Weiwa. The function is very powerful, and it feels very easy to use. It can query the number of exercise steps, sleep, weight, heart rate and historical data, query the power of the bracelet, display push, voice setting alarm clock is very useful, and check the weather, etc. It's too convenient.

▲ The first one in the above figure is the third interface, My information interface, and the three pictures on the right are respectively the WeChat Sports Leaderboard, QQ Health Leaderboard and Contact Customer Service interface. You can share the sports data with your friends to compare who is better.

▲ In my information interface, click Discover to add various tests, such as weight loss test, health assessment, fitness assessment, sleep assessment and psychological assessment. There are many weight loss tests, as shown in the figure above. There is only one health assessment for cervical spondylosis. There is one fitness evaluation item, and the test is selected for the fitness plan. There is one item of sleep assessment, which is sleep quality test. There are two psychological tests, namely, anxiety analysis guidance test and depression analysis guidance test. By default, there is no test. Click the plus sign to add it. For example, if I add a cervical spondylosis test, the background will automatically pop up a question. Click Yes or No, and the conclusion will be displayed after answering. Nowadays, many young people are sitting in front of computers for a long time and playing with their mobile phones. It's easy to get cervical spondylosis. We really need to pay attention. We will move our heads for a while.

▲ At In my information interface, click Help and Upgrade, and you can see three contents: adaptive models, FAQs, and firmware first-aid kit. The compatible mobile phone types of the client are listed in the adapter models, and some compatible mobile phone models are listed. Frequently asked questions include questions about existing products, but there are no frequently asked questions about i7. The version can be displayed in the firmware upgrade, and how to solve the problem. Click Upgrade in the device list.

The voice interface and my information interface are basically introduced. The following is mainly about the information on the home page for your reference.

▲ To use the bracelet for the first time, click the top of the home page to connect the bracelet, select your own device, click Connect when it is displayed, and the device status will be displayed after the binding is successful. You can also set the ring here, including sitting reminder, message push and backlight settings. By default, the opening time displays 24-hour system, automatic sleep, wrist turning gesture and Chinese English switch. By default, the black and white screen switch and segment connection reminder of the dial are turned off. If necessary, it can be turned on. At the bottom is the firmware upgrade, and the upgrade of my information interface.

Next, we will introduce the long sitting reminder and message push in the device status.

▲ The reminder of sitting for a long time is turned off by default, and cannot be turned on directly. You must repeat the setting first, that is, the day of the week. You can also set the time period. Remind once every half an hour after opening "It's time to move", and a simple figure However, when I was shopping in the supermarket today, I even reminded me once. It seems that the accuracy should be improved.

▲ The function of message push is very practical. Call reminder and WeChat reminder are enabled by default. Click Set SMS application to enable reminders such as information, and also QQ reminder. In addition, other software push can also be set.

▲ At the bottom, there is a note about application message push, but it is still a zero one software, and it is not changed to the WeChat Health Assistant.

2. Main functions of APP homepage

▲ Calorie target setting. The first row in the homepage is calorie goal setting. There are two kinds of sports goals to choose from: keep healthy and lose weight. You can choose by yourself. After goal setting, you can also modify the goal in the upper right corner. The default type of motion is set as walking. You can add 23 types of motion, including ball games, rope skipping, sit ups, mountain climbing, cycling, yoga, etc.

▲ The second line of data is step statistics, which will display the walking time, distance, duration and speed. The sleep data shows the sleeping situation last night, including the time of deep sleep, light sleep and waking up, as well as suggestions. But how can I stay awake for more than an hour? It's a bit strange. I haven't been playing mobile phones for so long in bed in the morning.

▲ Above are alarm clock, schedule display, weight and suggestions, heart rate chart of the day and historical records. The alarm clock and schedule can be set up directly by voice or added in the upper right corner. In the weight chart, after a long time, it always shows that the device is being searched. The following information is also 0, and there is no display. Evi i7 is a heart rate bracelet. To display a heart rate chart, you must turn on the automatic heart rate on your watch. You can also view the historical heart rate chart, and display today's exercise in color. Heart rate function is very good.

▲ There is also a very important function on the home page. Click the record button in the upper right corner to see two very important functions. The first is GPS movement and smart photography. Click GPS Sport. After GPS is enabled, the cycling, running, jogging routes and data can be recorded. After clicking Start, the interface as shown in the third picture above will record the distance, duration, speed and average speed. The above map has been processed. The function of Smart Beat is actually to use the watch as a self timer remote control. See the function experience section for specific use.

＊ Function experience of i7 bracelet ＊

1. Magnetic charging

▲ The i7 bracelet can be connected to the computer USB port or directly connected to the mobile power supply for charging demonstration. The watch body is equipped with a 100mAh polymer lithium-ion battery. According to the publicity, the real-time heart rate can last about 7 days when it is turned on, and about 30 days when it is turned off. According to the test, the real-time heart rate can be turned on for about 5 days. When charging some bracelets, you need to see the direction. If you don't put them in the right place, you may find that they cannot be charged after a long time. However, if the charging line interface of the i7 bracelet is not in the right direction, it will repel. Only when the direction is correct, can it be well contacted, so as to avoid the problem that the charging line is not in the right direction for a long time.

2. Turn on the bracelet

▲ Press and hold the screen to open the bracelet, or the bracelet will automatically open when charging.

3. Main interface of bracelet

▲ The bracelet mainly has four interfaces, sliding left and right, and the default time interface is displayed. The second is movement, the third is message, and the fourth is function.

4. Time main interface

▲ Slide down from the time interface to display today's step statistics, distance statistics, heart rate, calories consumed, and how far from the set target value. Note the heart rate here. It will take a while to display the reading.

5. Motion interface

▲ The sports interface slides down. By default, there is only one running, but it is said that there are more than 20 sports. How can it display only one? Well, you need to add movement in the first row of data target setting in the APP before it will be displayed on the watch. Please refer to the introduction of the APP main interface in the previous section. The types of sports include: walking, sit ups, push ups, rope skipping, mountain climbing, pull ups, badminton, basketball, football, volleyball, table tennis, bowling, tennis, cycling, skiing, ice skating, rock climbing, fitness, dance, plank support, aerobics, yoga and shuttlecock ball, a total of 23 kinds. Please note that the APP here counts walking and running as one item, which should be 23. The APP displays walking, but the watch sports mode displays running icon, which is also a default sports mode, as shown in the figure above.

▲ When starting the movement, you can select the corresponding movement mode in the watch, and long press Start, and long press End to display the movement data. However, if you want to display the route map of the movement, you must turn on the GPS movement in the record in the upper right corner of the APP, and turn on GPS to display the route. After saving, you can see the historical data, as shown in the above figure.

6. Message interface

▲ When QQ and WeChat reminders are enabled in the APP, Bluetooth is always enabled. When there is a message, the watch will remind you. You can click to view it. By default, up to 8 messages are displayed.

7. Function interface

▲ Scroll down from the function, the main functions are: equipment search Photo taking, music control When you want to enable the function, you have to press and hold the button for burning mode, changing dial, automatic heart rate, black and white inversion, language switch, QR code, and shutdown. Click the device to search, and the mobile phone can give an alarm to facilitate the search of mobile phones. When using the smart shooting function, click "take a picture" to open the bracelet. The burn in mode is the manufacturer's and can be ignored. Turn on the automatic heart rate here, and the bracelet will keep recording. The black and white reversed color changes the background color. To close the bracelet, click Shut Down.

▲ The QR code displays the version information of the bracelet, and the voice can be switched between Chinese and English, but everyone should pay attention to that the switch is in English, no English is displayed, and all the icons have changed their flavor. It is recommended that you choose the default Chinese version. The music control is still very good, but the Meitu mobile phone I use has failed to use the default music player, Kugou and Kuwo players. I wonder if it has anything to do with the mobile phone.

▲ The first dial in the figure above is displayed by default and can be changed to the other two.

8. Smart shot function

▲ The i7 bracelet can be used as a self timer remote control, which I think is very convenient. The Meitu mobile phone I used to use cannot use an ordinary selfie stick, but it takes more than 80 people to buy a Meitu remote control. With a bracelet, you don't need to buy a selfie remote control. The above figure shows the APP smart shot interface and the photos taken. The photos are saved in the album and named DICM. In addition, in the upper left corner, the camera can be switched. The rear camera can be activated as standard, and the front camera can be activated as self timer. Click the camera icon in the upper right corner, You can choose to auto focus or take a single photo, Take three photos by default . However, you can take photos with the bracelet only after you click the record in the upper right corner of the APP and turn on the smart shooting function. You cannot start the camera with the bracelet.

▲ The photo button of the bracelet. Touch it to take a picture, and the bracelet will shake.

5. Heart rate curve function

▲ The heart rate bracelet commonly used before is 37 degrees, which is compared with Ivy i7 when used.

▲ The back of both bracelets are heart rate sensors and charging contacts.

▲ When measuring heart rate, the heart rate sensor on the back will display a green light.

▲ The 37 degree bracelet used previously to measure the heart rate is usually measured on the whole hour, or manually opened to measure the heart rate, but the 37 degree bracelet is still very cost-effective. Aviva i7 has a real-time heart rate function. After it is turned on, You can view the heart rate curve of the whole day, and also observe the heart rate during exercise. There are five stages: aerobic exercise, anaerobic exercise, cardiopulmonary exercise, fat burning, or heart rate warning, reminding you to exercise healthily. In addition, you can view the previous heart rate in history. It is observed that the heart rate measured with the Evi7 bracelet and the 37 degree bracelet is similar.

＊ Wearing experience of Evian i7 bracelet ＊

▲ In terms of face value, Evi7 really has room for improvement. Moon frost wins in beauty.

▲ When wearing the Ivy i7, you have to press the button hard, and often press it several times to succeed.

▲ The bracelet display is also very clear in the strong noon sun.

▲ It is clear that the backlight can be turned on at night.

▲ I wear the Evi bracelet to travel, which is used to record the sports data during the travel and see the daily activity.

* Summary *

Here is a summary of the advantages of the i7 bracelet and some suggestions for reference.

advantage:

1. A variety of watchband colors can be selected, and the wearing comfort is fairly good.

2. Step counting, sleep, alarm clock, heart rate, exercise recording, and photo taking functions are all available. The characteristic is real-time heart rate.

3. During magnetic charging, if the direction is reversed, it will repel, so as to avoid the problem that the direction is not set in the right direction and the power cannot be charged for a long time.

4. The voice assistant Weiwa is very easy to use. It can ask all kinds of data. Voice can set up alarm clock, intelligent question and answer, etc. It's great.

5. In the APP My Information Interface - Discovery, there are various health tests that can be done to better understand your body and urge you to pay attention to health problems.

6. Turn on real-time heart rate, and you can see the heart rate curve and history on the APP.

7. GPS sports and smart photography functions are great. GPS sports can see the routes and data of cycling, running and jogging. The smart beat function enables the bracelet to be used as a self timer remote control, which is very convenient.

8. Click the device to search, and the phone can send out a prompt tone, which is convenient to find the phone.

9. When exercising, if there is an incoming call, you can hang up directly through the bracelet.

Suggestion:

1. The Bluetooth pairing described in the APP in the manual is still the pairing method of the old version of the APP, and now the new APP has been changed to the WeChat Health Assistant. The manual should also be changed. In addition, the word "zero one" can also be seen in the new version of the APP. If you are a new user of the WeChat bracelet, you may not know what "zero one" is. We should know that "details determine success or failure". Only by doing every aspect carefully, can we win the trust of customers.

2. Click Help and Upgrade on the My Info interface of the app. The common problems are not related to the i7 bracelet.

3. There is still a lot of room for improvement in the appearance of the Evian i7. The logo of the iwown brand cannot be seen on the whole bracelet. In fact, there is a large area under the dial. I think it is no problem to print the logo, and it also plays a role in publicity. When a friend asks which bracelet he is wearing, why should he write the brand to them.

4. The touch on the surface of the Evian i7 bracelet is not very sensitive. You have to press it several times, which is a bit unbearable. It really needs to improve the user experience. In addition, When you need to select a function on the dial, a short press at the beginning does not respond, but a long press is required.

5. In the sports mode, there are 24 kinds of sports for publicity, but the actual default display is only the running mode, which requires users to add corresponding sports to the target settings in the APP. In the APP, running and walking are classified into one category, with 23 kinds in total. The APP adds walking by default, but the running icon appears on the surface, which is a bit confusing. Walking and running should be separated and displayed with different icons. This is exactly 24 sports modes. I see many people on the Internet asking why there is only one kind of sport on watches. I don't know how to add it to the APP, but it can be explained in the manual.

6、 Remind me of sitting for a long time. When I was shopping in the supermarket, I even had a reminder. I need to improve the accuracy.

7. On the APP weight page, the device search is always displayed. Please wait, it is clear that the bracelet has been connected.

8. The burn mode in the watch function is used by the manufacturer. This option can be removed to avoid misleading.

9. Taking off the watch and putting it on the computer keyboard, the heart rate will also be displayed, which makes people doubt the accuracy of heart rate measurement of the bracelet.

10. Stand still, shake your hand, and the number of steps will be recorded. In addition, if you walk with your hands behind you, the number of steps is not included. But this is also a problem with many bracelets. The step counting algorithm is still worth considering, and the accuracy needs to be improved.

11. The actual dial style is not quite the same as the promotional pictures at the beginning.

12. The watchband button is not particularly easy to fix, and you have to press it several times to succeed.

13. Among the watch functions, the music control function I did not try successfully on the Meitu mobile phone, which may only be suitable for some models.

14. The endurance can be improved.

It is expected that the functions of Evei bracelet can be gradually optimized, improve the user experience, protect the health of users, and become a health steward.
