preface

The nationwide movement has spawned a boom in intelligent sports equipment. However, professional smart sports watches are too expensive, such as Suntuo and Jiaming, which often start at thousands of yuan. The smart sports bracelet known for its cost performance has become the first choice of the public. However, how about the actual experience? It can only be worn when exercising. The time and date cannot be seen when wearing it in daily life. The relevant intelligent elements such as step counting and notification can only be used with mobile phones. To be honest, it is a bit lame. It is believed that an affordable intelligent sports equipment that can bring users a new experience will be popular in the market.

Today, the author will introduce a smart bracelet that can display time, date, 24-hour heart rate and sleep monitoring - Le Xin bracelet ziva. The new Le Xin bracelet ziva uses Italian calfskin wrist strap, which is more comfortable to wear. PowerPulse heart rate algorithm is used to monitor heart rate once a minute in real time, and can store user movement data offline, Automatic synchronization of motion data when connected with mobile phones, and automatic generation of concise motion data and heart rate curves, so that users can see the movement data of a day or even a week at a glance, successfully solving the needs of most users.....

Unpacking

Lexin bracelet ziva is designed with double-layer packaging materials. The outer packaging is made of hard kraft paper, which is energy-saving and environmentally friendly. The front center is the logo of the "Lexin" product, and the side is Ziva's product name. It looks very simple and solid on the whole.

After opening the outer packaging materials, it was found that the interior was the real product packaging of Ziva. The outer packaging was just for protection. The overall packaging box was designed with warm colors, bringing a sense of warmth to the opening in deep winter. The front center of the packaging box was Ziva's product physical image, small and delicate, the side was the product logo, and the back was the product related information As well as listing the features of the product in the form of icons, such as heart rate monitoring, heat, notification, step counting, sleep monitoring, etc.

The side of the box is ingenious. One side is made of transparent plastic material. The bracelet products inside can be clearly seen from the outside, which brings many surprises to unpacking. I can't wait to get started.

The music heart bracelet ziva has three official colors, namely rose gold, champagne gold and deep space grey.

From the color point of view, the one I got should be rose gold, black LCD screen, quiet and profound, rose gold watchband, romantic and fashionable. From the name, it makes people imaginative. The designer skillfully matched them together to achieve a good color contrast design. After opening the outermost layer of Lexin packaging, you can see the surprise brought by the package of Lexin bracelet Ziva.

After opening the plastic cover, you can take out the ziva bracelet. It's too simple to talk about such a large box. There is only a black accessory box with a product manual inside. The charger and charging line are not seen. Of course, it's not that the manufacturer forgot to pack it, but this bracelet is ingenious in design. The body has its own charging device, which is really wireless charging.

Upgraded appearance and outstanding design

Compared with the Le Xin bracelet mambo, the appearance of the Le Xin bracelet ziva is upgraded and more fashionable. The rose gold wristband+black OLED, perfect color contrast, thin metal edging, and nano injection molding process make the overall line more smooth and the host more designed.

The music heart bracelet ziva is structurally composed of the body and the wrist strap, and the wrist straps on both sides can be disassembled. The inside of the wrist strap is designed with an original click wrist strap snap button, which can be pulled out by pressing.

Wireless USB direct charging interface

On one side of the body is the real wireless USB direct charging interface of the Lexin bracelet, which can be directly inserted into the USB interface for charging without charging adapter and charging cable. On the other side, the interface is ingeniously printed with the product serial number, and changing the wrist strap will not affect the integrity of the product.

It not only gets rid of the limitation of charging cables, but also reduces the interface of the fuselage, maintaining the integrity of the fuselage, and ensuring the waterproof performance of ziva.

0.87 "OLED touch screen with thin metal edge

The display part of the music heart bracelet ziva uses a 0.87 inch OLED touch screen, which is quiet and profound in black. The large screen can display relatively rich content, such as time, date, step counting, calorie consumption, mileage, heart rate... This is rare in the smart bracelet industry. The large screen will increase the power consumption and affect the endurance of the overall bracelet.

Ziva screen uses a brightness display screen. Don't worry about the influence of strong light on the visual effect. The hardness of the screen has reached 4H, which is close to the hardness of ordinary glass and is not easy to scratch. The night mode can be set at night. The light is soft and not dazzling, which can effectively protect the eyes from damage. It is a very considerate design.

With the thin metal binding design of the body part, the visual experience similar to that of a smart watch is realized on the bracelet for the first time.

The touch screen carried by ziva is sensitive, placed on the inside of the wrist, and can be interchanged between left and right hands. When the wrist is raised, the screen automatically lights up to display the clock and date, which is easy to operate.

Independent display of clock, date, heart rate, step count and mileage without mobile phone

It is worth mentioning that Ziva has built-in ARM Cortex-M4 core processor, which is not a bit better than the ARM Cortex-M0 core processing of similar bracelets on the market. This processor, together with the 0.87 inch OLED screen, enables Ziva bracelet to work independently from the mobile phone. By clicking the touch screen, you can gradually switch the display contents, including time, date, step, mileage and heart rate, The movement data is automatically stored offline in the bracelet body. When the bracelet detects that the Bluetooth is connected to the mobile phone APP, the movement data is automatically synchronized to the mobile phone APP, completely saying goodbye to the dependence of mobile phones and making sports light.

24-hour heart rate monitoring, your heart rate is unique

Heart rate monitoring function is the most popular intelligent element of sports equipment, and also the core function of the smart bracelet to focus on health and sports effects. The heart rate bracelet ziva is equipped with ARM Cortex-M4 core processor, and a Deyi heart rate sensor is mounted on the back.

Heart rate is one of the main functions of Lexin bracelet ziva. With green LED and PowerPulse dynamic heart rate monitoring algorithm designed independently by Lexin, heart rate is monitored every 1 minute to realize 24-hour heart rate monitoring function.

Calfskin wrist strap imported from Italy, waterproof and wear-resistant, comfortable to wear

I have to say that Ziva's wristband is the most comfortable one among all the smart bracelets I have experienced. It is made of leather. I can't find out whether it is Italian imported calfskin.

Different from ordinary silicone wristbands, this wristband has good permeability, moderate hardness, no abrasion to the skin, and good skin friendly effect.

For a few days after wearing Ziva, there was no feeling that something had to be removed from the wrist when sleeping at night.

To make a brief summary, the rose gold color matching of the music heart bracelet ziva is fashionable and romantic, with a streamlined design. The 0.87 inch OLED body is supplemented by thin metal edging, which not only does not lose strength, but also maintains the beauty of the shape, with a strong sense of design. On the basis of high beauty, the calf leather wrist strap also maintains the comfort of wearing the bracelet, and it is hard to say that there is something you don't like.

Experience

In addition to being able to use Ziva independently from the mobile phone, Lexin bracelet can also realize more functions through Bluetooth connection to the mobile phone app "Lexin Sports".

Users can scan and download the "Lexin Sports" app from the official, application market, and bracelet box QR code. Lexin Sports App is a mobile client designed for sports, but it can achieve personal challenges, mobile phone steps (with or without a bracelet), group competitions, etc. The installation, registration, and login of software apps will not be wordy.

The author has been using Lexin's smart sports watch for a while, so he does not need to download the APP again. After logging in, the device displays the bound Lexin watch mambo watch. When you click to add a new device again, the software prompts that you need to unbind the mambo watch before you can bind the ziva bracelet, why？ It is troublesome to switch in this way, which is a pity.

The process of unbinding the mambo watch, reconnecting and binding the ziva bracelet is relatively smooth and fast. The software terminal displays the device power, serial number, and firmware version. The previously set movement goals can be seamlessly switched, such as exercising 7000 steps a day and weighing 66Kg.

For the first firmware update after Ziva is powered on, the software is automatically completed without manual participation.

Lexin Sports, Sports+Social

There are four modules in the APP, namely "Home", "Group", "Discovery" and "My". Personal sports related data and settings are mainly focused on the "home page" and "my", which will be introduced as a key point below, while "group" and "discovery" tend to be social sports, which will promote and popularize the enthusiasm of sports to a certain extent.

Step counting statistics

The "Home" interface design is divided into top and bottom card structure design, which is relatively simple and clean. The upper part is a step counting card, which shows the number of steps that have been taken today. The lower part displays the current calorie consumption, movement target, and kilometers of walking; The lower part is the heart rate, weight, sleep, and exercise list, which shows the current data in a concise way without too much redundant information. Click to click the detailed information of the number of steps taken, and the statistics of the number of steps taken in the last day, week, or even month. When walking into running, Ziva can automatically open the running mode according to the monitored changes in heart rate and step frequency, and record accurate dynamic heart rate in real time.

24-hour heart rate monitoring

Lexin bracelet ziva has built-in ARM Cortex-M4 core processor+high-precision heart rate sensor, together with Lexin's independent heart rate algorithm, so that this bracelet can accurately monitor heart rate changes, make independent measurements every 1 minute, and monitor heart rate 24 hours a day, including sitting, exercising, happy, sad, The heart rate curve can be directly displayed on the OLED display screen of the bracelet+APP to record the heart rate curve. The curve is bright. The test results of the author in the scenarios of sitting still, after exercise, before sleep, and hand washing show that only after hand washing, there is a prominent deviation. I guess that water splashes between the heart rate sensor and the skin, causing partial deviation to the monitoring results, The overall experience is relatively smooth.

Sleep monitoring

The sleep monitoring function of Lexin Sports uses algorithms to accurately identify users' deep sleep, shallow sleep, and awake states, and stores them offline in the bracelet. When the bracelet is connected to the mobile phone APP in the morning, sleep data is automatically synchronized, and curves and histograms are drawn. Users can clearly understand the sleep quality of last night, and make adjustments according to the sleep recommendations of the APP, The author actually checked yesterday's sleep situation, and the result was quite accurate. Last night, he got up at about 4 o'clock to go to the bathroom. The result showed that this time period on the curve was awake, but whether the algorithm for calculating the state of sleep was scientific still needed long-term practical experience.

In addition, Lexin Sports APP also has a lot of functions, such as long sitting reminder, WeChat SMS message reminder, call rejection, wake up alarm clock, etc. For example, some annoying guys harass you by phone in the early morning, but they don't want to get up to hang up on their mobile phones, then just click on the Ziva screen to reject calls. For example, if you set an early alarm clock to exercise, the children and their families are asleep, Ziva's alarm clock is only used to remind people through vibration to avoid disturbing family rest. It is very considerate.

Let's make a summary. The Lexin Sports App plays a more powerful role in the use of the Lexin bracelet ziva, greatly enriching the use scenarios of the Lexin bracelet ziva. The 24-hour heart rate monitoring curve, daily, weekly and monthly sports data statistics, let you know more about the body and make sports more scientific, while the message reminder, call display and call rejection functions, left and right hands Smart elements such as horizontal and vertical screen custom settings have greatly improved the intelligence and convenience of life, and the social elements of group games have greatly improved the enthusiasm of sports. In addition, "WeChat Internet" is a major advantage of Lexin. You can easily view sports, sleep and daily sports by binding WeChat.

About endurance

According to the official data provided by Le Xin Ziva, the 24-hour heart rate monitoring can last for 7 days; When heart rate monitoring is off, it can last for 30 days.

In the last few days when the author got hold of it, the 24-hour heart rate monitoring, message reminder, long sitting reminder, caller ID display, etc. were all turned on, and the battery power dropped from 80% at the beginning to 60% now. If this is the case, there should be no pressure on the 7-day endurance. Of course, you can also choose to turn off the heart rate monitoring to save power and extend the endurance.

In addition, when the power of the bracelet is too low, it will automatically enter the power saving mode, which can last for another 8 hours.
