Smart wearable devices have developed rapidly, among which smart bracelets and smart watches are undoubtedly the two most popular wearable devices. I have used millet bracelets, but the experience is not perfect due to the lack of a screen With powerful functions and professional heart rate monitoring, I am lucky to get a trial opportunity in the znds crowd test. Let's talk about my use evaluation

Unpacking

The Evian i7 adopts the upper and lower box cover packaging design, which makes people feel simple and fashionable. The silver LOHO is printed on the front of the smooth rectangular white paper box, which will have a reflective effect in the sun. Personally, I like this packaging style.

The information on the back includes: model, manufacturer, system parameters, QR code, barcode, after-sales telephone, etc., and the brand logo and model are on both sides.

The first thing you see when you open the cover is the card with logo printed on it. Next are the instructions, bracelet and special charging line. The bracelet is placed in a special protective sleeve to prevent it from being damaged during transportation.

appearance

The i7 adopts a square design. The mainframe is a black 316L all metal shell. The front of the dial is made of 2.5D ultra-high strengthened curved glass, which has excellent scratch resistance. There is no problem in daily use. With the black TPU wrist strap, the workmanship is better than expected, and the square small screen is still blank when not turned on

The heart rate sensor is in the middle of the back of the dial, with English brands and brands on the top, and three small columns below. It is the charging magnet interface. In order to prevent users from not knowing the positive and negative directions when charging, the Evian i7 uses the magnet principle to distinguish the charging sequence. It cannot be installed in the opposite direction. The Evian i7 is equipped with a 100mAh polymer lithium ion battery, For the capacitive screen with non color screen, 100mAh is enough

Use of bracelet

The Evian i7 didn't have any buttons. At first, I didn't know how to start the machine. After reading the manual, it was clear that the way to start the machine was to press and hold the bracelet screen until the bracelet shook. The display effect of the screen was good, black and white. The power consumption of the equipped screen is extremely low, and even in strong light, it can still provide a clear display effect, which is very practical.

The main interface displays Bluetooth connection, power, time, date and week, and the display mode includes white characters on black background and black characters on white background, which can be set in app,

The number of steps, kilometers, heart rate and calories consumed will appear when sliding downward. Please slow down when sliding, so that the recognition rate will be high

Swipe left to display motion, message and function respectively.

There are five modes when the movement interface slides downward. Long press to start various modes. Other modes, such as cycling mode, can be added to the Ewe Health Assistant app.

After sliding up the message, you can view the latest WeChat, QQ and other software and SMS messages. You can save 8 messages. Each screen can display 35 words of content. Sorry, the phone didn't receive the message when taking a picture, so it didn't display it.

Under the function, there are shutdown, equipment search, dial replacement, automatic heart rate, two-dimensional code, and shutdown.

The dial has three modes to choose from. I feel that there are fewer modes. I hope they can be increased later. Personally, I prefer the default dial

After the automatic heart rate is turned on, the heart rate sensor on the back of the bracelet will collect data. According to the official introduction, Evian i7 uses PPG (photoelectric heart rate measurement). In short, it emits green light through the skin, detects the change of reflected green light, and depicts the characteristics of heart rate change. It emits ordinary green light, which is harmless to human body. Slide down the main interface to monitor the heart rate in real time, and you can see that the size of the heart icon on the screen changes.

There are also photo taking and music playing modes in the function. This should be noted that the bracelet must be disconnected from the app and connected to the mobile phone via Bluetooth before it is displayed. The bracelet can control the volume and track switching of music played by the phone, but there is no pause and play options. The mobile phone can be placed on the stand to take photos remotely to prevent shaking.

App experience

The app of Evi7, EviHealth Assistant, supports Android and iOS, two mainstream platforms. It can be installed by scanning the QR code on the package box. The start interface of the software has a green frog, which is very cute.

The Bluetooth connection is very fast. It is troublesome to repeat this step every time the connection is disconnected.

This is the main interface page of the software, on which there are various data monitored by the bracelet. At the top, there will be a superman silhouette to match the comprehensive data and compare the image.

This sleep detection data, including sleep data analysis, main factors affecting sleep, light sleep, deep sleep, and time period display, is clear and vivid.

Click "Connected" in the first column to enter the device status. There are not only basic settings such as long sitting reminder and message push, but also backlight settings, Chinese English switching, black and white screen switching, and bracelet screen desktop switching.

summary

Advantages 1. The all metal body is small and does not feel heavy, so it is suitable for both men and women;

Advantages 2. The bracelet is easy to operate. It only has two movements: downward and leftward. It does not need instructions at all. You can start playing it once

Advantages 3. When the automatic heart rate function is turned on, the battery life is basically satisfactory,

Advantages 4. Adsorption charging is more convenient and fast than the Xiaomi bracelet I used before, which is a very good idea.

Advantages 5. The call can be hung up directly, which is very practical and eliminates the trouble of taking out the phone from the pocket,

Advantages 6. The function of reminding people of sitting for a long time can be enabled through the mobile phone APP, which is a good reminder for people who sit for a long time,

Disadvantages 1. The bracelet is separated from the mobile phone and cannot set the alarm clock independently. I hope it can be improved in the future

Disadvantage 2. The historical data will be cleared after the account is changed. It is hoped that the user can choose whether to clear the historical data when uninstalling.

Disadvantages 3. The bracelet vibration amplitude is small, the time is short, and the alarm clock vibration in the morning is sometimes not felt.

Disadvantage 4. The screen display is too jagged, which affects the overall aesthetic feeling.

The i7 smart bracelet has a good experience in motion monitoring, sleep monitoring, heart rate monitoring, information push and other functions. It is also very comfortable to wear, and there are also areas that need to be improved. However, from the perspective of price and product, it is still very competitive.
