Today, I would like to share with you a professional level smart bracelet provided by Lei Feng for free trial - Le Xin smart bracelet ziva.

Lexin smart bracelet ziva is a smart heart rate bracelet released by Lexin Company in 2016, which can realize 24-hour continuous heart rate monitoring, automatically identify the movement mode, and bring its own night mode, information reminder, long sitting reminder IP67 waterproof and other functions. The leather wrist strap imported from Italy is used with fashionable metal body.

Unpacking:

The express packaging of Ziva smart bracelet adopts the design of inner and outer boxes. The outer box is a special express packaging box, and the inner box is the real packaging box of Ziva. The outer packing box is printed with the words "Le Xin" and the brand design, and also affixed with the label "Try out". Remove the outer packing box and you will see the ziva inner packing box. On the front is a creative picture with the words "ziva" written on the top and "Your heartbeat moment" printed on the bottom（ Your heartbeat is unique). On the back is the introduction of product features+product model identification+relevant parameter information. On the four sides are the product barcode and brand logo. The overall design of the packaging box is very beautiful, giving a sense of fashion and atmosphere. It is very close to this smart bracelet. However, on the packaging box, the author did not find that the mobile phone APP matching the bracelet can download the QR code, which is somewhat inconvenient. It is suggested to add the QR code to the packaging box for users to download.

Different from the front opening and closing design of ordinary products, Lexin Smart Handband Ziva adopts a novel side opening and closing design. On one side of the box, it is sealed with high-quality hard transparent plastic. At the same time, it is protected by a fixed paper box+hard foam. On one side of the box, there is a small box with "Quick Guide/Lexin Handband Ziva Manual/Warranty Card Certificate", The design of combining various scattered instructions is very simple and fashionable.

appearance:

The size of Le Xin smart bracelet ziva is 17 * 10.8 * 250mm (including wrist strap). The corners of the oval shaped dial are round and delicate, and the streamline appearance is very small and beautiful. The lower part of the screen is a fashionable and beautiful metal frame with even and full color. It looks very fashionable and pleasing, and is very suitable for sports, daily life, work, business Wear on social occasions.

Lexin smart bracelet ziva is designed with 0.87 inch OLED display screen. There is a touch button at the bottom of the screen to control the bracelet. You can view the time (including date/week), heart rate, exercise steps, distance, calorie consumption and other related data on the screen. You can also press and hold the touch button to enter the exercise step recording mode.

On the back of Ziva is a slightly convex adaptive embedded skin type photoelectric sensor. The slightly convex shape design can not only ensure the accuracy of heart rate monitoring, but also ensure the comfort of wearing. There is also a USB tag on the top, so you can clearly know the location of the USB, which is very meticulous and user-friendly.

The unique design of click wrist strap snap fastener and the material of calfskin imported from Italy are used in the wrist strap of Ziva, which is soft and delicate and very comfortable to wear. At the same time, the wrist strap and the main body of the wrist strap are fixed by pressing and taking out the design. Pressing the upper part down can take off the wrist strap. This design can ensure that the wrist strap is firmly connected with the main body of the wrist strap, and it is convenient to take out the wrist strap for charging, The design is very novel and innovative. The charging mode of this bracelet is universal USB access. Different from other products, the Lexin smart bracelet ziva uses a hidden USB design, and is an embedded integrated molding technology. Even if the charging interface is completely exposed, it can also ensure excellent waterproof effect.

Experience:

Wearing: As an intelligent wearable product, you must ensure that you can wear it comfortably. The Lexin smart bracelet Ziva adopts an ergonomic bending radian design, which fits perfectly with the wrist. The 22g lightweight body and the press button hole wear design make it feel very correct to wear it on the hand. However, the size of 17 * 10.8 * 250mm is slightly smaller for men. It is suggested that large screen men's model and small screen women's model can be launched according to the applicable crowd in the future.

Mobile APP: Lexin smart bracelet ziva supports the use of Android and Apple devices, both of which have the corresponding mobile APP - Lexin Sports, the latest version of Lexin Sports 2.3 APP for Android devices, The UI design is clear and simple, the architecture layout is reasonable, and the operation is intuitive and simple. In the "home page", you can directly view the movement steps, heart rate, sleep status and other data of the day. In the "My" option, you can set the movement target, view the device status, and set other operations. At the same time, you can click each option to view the steps generated in different time periods of the day, It is displayed as a bar chart, and the data generated by the heart rate of the day is displayed as a curve chart, which is simple and intuitive.

The disadvantage is that it seems that the Lexin mobile app can only support the connection of one kind of device. Because the author has previously connected Lexin's mambo watch, when scanning the code to connect Lexin's smart bracelet Ziva, he will be prompted with "the device has been bound, please unbind the original bracelet before scanning". Only the previously bound Lexin mambo watch can be unbound, and then scanned the unique two-dimensional code of Ziva can be bound successfully, This should be due to the imperfect software design, and it is recommended to optimize and improve it later.

Screen manipulation/wrist lifting for interactive experience: Le Xin smart bracelet ziva uses touch buttons to manipulate, touch once to display time, date and other information, touch again to switch, through touch switching, you can view heart rate, movement steps, distance, calorie consumption and other related data, of course, you can also long press the touch button to enter the movement step recording mode. The actual experience is sensitive to touch, and the screen display is clear without delay and dazzling. The night mode can also be set in the mobile APP, which is very good. In addition, the response of Ziva's wrist lifting and screen lighting is relatively sensitive. Every time you lift your wrist, you can basically wake up the screen, but occasionally there is no wake-up effect or a slight delay. It is recommended that you continue to optimize and improve it in the future.

Motion counting for interactive experience: As an intelligent wearable device, motion counting is one of its essential functions. Through experience, it is found that the motion counting of Le Xin intelligent bracelet Ziva is more accurate than similar devices, and there is a special motion recording mode, which can better help users record the details of movement.

Heart rate monitoring for interactive experience: The heart rate intelligent bracelet Ziva adopts 24-hour real-time heart rate monitoring. The slightly convex photoelectric sensor can better fit the skin and improve the accuracy of monitoring data. At the same time, Ziva can record the real-time heart rate once a minute, automatically generate a smooth and coherent heart rate curve, so as to better help users understand the health status, scientifically arrange sports, You can also check the resting heart rate, which is the most promising innovation. But the heart rate monitoring function is 24 hours a day. You can set whether to turn it on or off in the mobile phone APP, but you can't select a time period for monitoring. In fact, not all users need to monitor their heart rate 24 hours a day, nor can they not monitor it 24 hours a day. In addition, turning on the heart rate monitoring function 24 hours a day will increase power consumption to some extent, Therefore, it is suggested that it would be better to add user-defined heart rate monitoring time periods in the future.

Sleep monitoring of interactive experience: Le Xin smart bracelet ziva can automatically track the user's sleep time at night, analyze the sleep quality by drawing a sleep trend chart, and give some reasonable and practical suggestions according to the user's sleep quality. This is a very useful and meaningful function in the author's opinion. After all, due to the pressure of work and life, More and more people can't sleep at night. Ziva can help users better understand their sleep status, and can make targeted improvements according to the suggestions given, and can also interact.

Durable and waterproof: The Le Heart smart bracelet ziva adopts a detachable and hidden USB waterproof design. When the watch needs to be charged, just press the button on the inside of the strap to take out the bracelet body, and then connect it to the charger to charge it, Ziva has a built-in 78mAh battery, which takes about one hour from empty (about 1%) to fully charged (100%). The author has 60% of the power left after 8 days of normal use under full charge, so it can be inferred that the normal use of a fully charged battery for two to three weeks is no problem, and the endurance performance is better among similar products, which can meet the use needs of ordinary users. However, there is no residual power display on the watch screen, and it is unknown when to charge, which affects the user experience. It is recommended to add residual power display in the watch later. In terms of waterproof, the author did not deliberately take swimming and other underwater sports with him. He just immersed Ziva in water and took it out after about 30 minutes. Ziva bracelet works normally, which shows that this bracelet should be waterproof for daily life.

Summary:

With the improvement of living standards and the change of consumption concept, people no longer pursue low-cost intelligent wearable products, but pay more attention to the upgrading of product quality, performance and functional experience. In this context, consumers are more eager to purchase high-quality, good service and more professional intelligent wearable devices to improve their quality of life. Under this background, Lexin officially grasped the consumers' psychology and launched a sports health and professional Lexin smart bracelet, ziva, which can help users understand their own smart heart rate more accurately. If the above shortcomings can be improved, optimized and perfected, it is believed that it will become a high-quality intelligent wearable device that consumers love and trust.
