[Preface]

Smart wearable devices, especially the bracelet, have entered a popularization period since the Xiaomi bracelet. Almost everyone has one. The price advantage of the Xiaomi bracelet has undoubtedly played a great role in promoting its rapid promotion at the initial stage. However, the lack of a screen makes the Xiaomi bracelet look a bit weak. Even the new generation 2 has only added the heart rate function. Today, we experience the Ivy I7 smart bracelet, It not only has the functions of conventional bracelet applications such as heart rate, sleep monitoring, long sitting reminder, and step recording, but also has the functions of smart watches such as time display, instant messaging, and call display because of the screen. So I think it is not too much to call this smart bracelet Ivy I7 a smart watch.

Thank Lei Feng for offering this experience opportunity.

[Package and appearance]

The outer packaging of Evo bracelet still follows the current popular simple style. The front of the rectangular white hard paper box is simple to only have the brand logo, and the back is the product's mobile phone client requirements, two-dimensional code, manufacturer and other information.

In addition to the bracelet, there are charging lines, instructions and an invitation card for reviewers.

The Evian i7 uses a square dial, and a 3161 all metal body and capacitive touch screen. The 2.5D ultra-high strengthened glass and the smooth arc design of the edge and the square dial are more suitable for Asian wearing lines and curves. There are no physical keys on the dial. The 39 * 31 * 8.4mm dial size matches only 30g weight, which is very lightweight.

The i7 also supports the heart rate monitoring function. The heart rate sensor can be seen on the back of the bracelet host, and the three metal contacts below are charging interfaces. The built-in heart rate sensor of Evian i7 is the top AMS dynamic heart rate sensor in the world. It uses PPG, that is, photoelectric heart rate measurement. In general, it depicts the characteristics of heart rate changes by emitting green light to the skin under the wrist and detecting the changes of reflected green light.

Evian I7 uses TPU medical grade skin friendly wrist strap with sweat drainage groove, which makes it very comfortable to wear. The buckle of silver band LOGO also adds a sense of fashion to ordinary wristbands; The zoom range of the 9 hole position is adjusted, which is more suitable for people of all shapes.

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.

Evo I7 also adopts the most popular magnetic adsorption charging design for smart bracelets and watches. When the back of the watch is close to the charger, it can automatically be adsorbed in place for charging. The gap marked by the red arrow in the figure can pack the charger without being inserted reversely.

The Evian i7 is equipped with a 100mAh polymer lithium ion battery, which is safe and efficient. According to official data, it can stand by for 7 days when the automatic heart rate function is turned on. If the automatic heart rate function is turned off, the endurance can reach an amazing 20 days. This endurance should be in the upper middle level among similar products. According to the actual measurement by the author, the i7 can basically last for 5 days when the automatic heart rate function is turned on, which saves a lot of trouble for daily use.

The screen of Evian i7 supports two display modes: white characters on a black background or black characters on a white background. The two display effects have different aesthetic feelings. You can choose black background when sleeping at night, but you can choose white background during the day. Of course, both display effects are good. In addition, Evian i7 also has a variety of dials in different styles, which can meet the different aesthetic needs of users. If you feel tired of aesthetics, you can switch freely at any time.

The i7 dial has no physical keys. The Memory display screen it is configured with is a capacitive touch screen that supports touch operation. In addition, the system UI is specially optimized for touch operation. With fingers gently sliding across the screen surface, you can call up various functional interfaces as you like.

I7 adopts the unique control mode of long press and slide. The specific operation method is: long press is to confirm the entry of the corresponding function, and slide is to select the function; It should be noted that the capacitive touch screen of i7 is not as sensitive as we thought, which may be to effectively prevent accidental touch. Therefore, we need to master certain tips in the use process to better play the touch function of i7, that is, click first and then slide slowly. For the operation mode, there is still a certain learning cost.

[Wear]

I really think it is a watch unless I say it. The same material of the strap and the light weight of the dial make it very comfortable to wear.

Comparison

And Weile Xiaohei 2 The appearance is simple and contrasted. The Evian I7 dial is smaller and thinner. At the same time, the Xiaohei 2 uses physical buttons, which is relatively cheaper to control and learn. From the back, it also uses adsorption charging, and I7 has more heart rate detection functions.

And the previous generation products of Evo I5PLUS In comparison with the appearance, the larger dial screen displays more messages. At the same time, the screen is always on, and the viewing time is more convenient. In terms of the buckle, I prefer the I5PLUS, which is more fashionable, while the I7 buckle seems to be a little more introverted.

Comprehensive comparison

[Function Experience]

As a smart bracelet, it is essential to use it with mobile phone APP,

The manual contains the QR code of the mobile phone client. We scan the code to jump to the official download address, download and install the official "Zero One" App of Evian. The software supports three login modes: "QQ login", "WeChat login" and "Zero one account". As for which login mode you choose, it depends on your habits. However, if you choose "QQ login", the exercise record of the bracelet will be automatically synchronized to the "QQ Health" platform. In addition, another app of Evian, "Evian Health Assistant", seems to have better support for bracelets.

Press and hold the host screen for a long time, and the machine will start successfully with slight vibration induction. The I7 bracelet still supports the connection with mobile devices such as mobile phones through Bluetooth. If you do not want to establish a connection with mobile devices such as mobile phones, it will not affect the use of the bracelet itself. After starting up, it can be used as a pure sports bracelet to count steps, calculate the heat burned, and accumulate the kilometers of movement. But I personally advocate connecting mobile phones through Bluetooth, because more practical functions of I7 rely on mobile phone clients.

The first step we need to do after landing is to bind the bracelet. Select device binding in the navigation bar that pops up on the left, and you can easily complete the binding according to the prompt. After binding, enter "Device Settings" to personalize the bracelet. Main functions include call reminder, WeChat QQ、 Information push reminder, self timer, mobile phone search, sleep monitoring, long sitting reminder, deep waterproof, wrist turning gesture, Chinese English switch, black and white screen switch, backlight setting, etc. Among them, "long sitting reminder" and "alarm clock reminder" functions are very practical for office workers. The former can regularly remind people to stand up and relax and drink water; The latter can let oneself be awakened by a gentle vibration rather than a loud bell in sleep. However, sometimes when a long-time sitting reminder is turned on, when you take off the bracelet and put it in your bag, you will also be reminded by vibration from time to time. If you can monitor the status of the bracelet taken off, it would be nice to have an intelligent reminder.

Another practical function is message push. The I7 bracelet supports "call reminder", "SMS reminder", "QQ reminder" and "WeChat reminder". (Phone permissions need to be set) After all of these are turned on, we can receive a response reminder when the phone Bluetooth and the bracelet remain connected. When the phone receives a short message, the bracelet will also vibrate the reminder and display a message summary. Through my own experience, the bracelet can remind users of common APPs such as incoming calls, SMS, QQ messages, WeChat messages, etc. However, users with a large number of QQ and WeChat groups are not recommended to open these two push messages. Constant vibration will accelerate power consumption.

In addition, I7 also supports the sleep monitoring function, which can be set to automatically enter sleep. The bracelet will automatically enter the sleep monitoring mode at a fixed time every day. Click the down arrow in the upper right corner of the application, and select the "Sleep" tab in the pop-up navigation bar. You will see your own sleep quality in the recent period.

In addition, I7 supports three kinds of sports: cycling, running and hiking. It records sports data in real time and generates statistical curves, which helps to understand your own sports situation and record calories consumed. It is also very helpful and can promote weight loss. However, since GPS is not supported, no motion track will be generated when the mobile phone is disconnected.

In addition, after opening the camera and adjusting the viewfinder, you can click the bracelet to complete shooting, which is the intelligent shooting function of I7. It is very convenient to take a remote selfie.

I7 also has a more practical function - looking for mobile phones! When the bracelet is connected to the mobile phone via Bluetooth, swipe to "Find Mobile Phone" and press and hold. When the bracelet vibrates, the mobile phone will sound an alarm.

Summary

advantage:

1. Equipped with touch screen, the display effect is excellent, and there are many message push display contents, saving the trouble of checking mobile phones;

2． Rich functions, especially the message reminder function, which can not only remind but also display content. At the same time, functions such as "looking for mobile phones" and "smart photography" are highlights of the product.

3． Waterproof and dust-proof, meeting the daily application. At the same time, the 7-day endurance is not only convenient, but also good without charging at any time.

four The wrist strap is made of comfortable material and has a fashionable overall appearance.

Suggestion:

1. Can I add the "nap" function to the alarm clock? After the alarm clock rings, I can click it to sleep for another 5 minutes.

2. It may be more intuitive if there is an interface digital display of the remaining power. After all, it is still troublesome to log in to the APP and connect via Bluetooth.

3. Add stopwatch and timing function.

4. The control mode is described in detail to reduce the user's learning cost.

In general, the functions of the Ivy I7 smart bracelet are very practical. The 7-day endurance is excellent for the function with a display screen and heart rate. It is comfortable to wear and fashionable in appearance. In terms of performance, it can be compared with a smart watch.
