The fast pace of life and irregular diet of modern people make many people's weight easily soar, especially girls who are not careful will become fat, and losing weight has become a major event for many people. If you want to do a good job, you must first sharpen your tools. If you want to lose weight, you must naturally have a good partner: the scale that can only show the weight simply has been out of date, and the intelligent scale that can measure body fat is the mainstream today.

At present, in addition to traditional medical device brands, there are also many Internet brand products in the body fat scale market. This time, the products of Yunkangbao, Lexin and Tsinghua Tongfang that we have reviewed have passed the medical device certification. What is the gap between the products that also pass the certification? Which is more suitable for consumers?

Appearance comparison

On the outer package, the packing box of Lexin S7 is the largest, which will slightly hinder the handling or storage; Yunkangbao Mate is much smaller than Tsinghua Tongfang Haotizhi. It is worth mentioning that Tsinghua Tongfang does not know whether it is worried about violent express delivery during transportation, and the outside is protected by a layer of kraft paper.

At present, the intelligent body fat scales are quite similar in appearance. Tsinghua Tongfang's HTZ M1 adopts a white panel design. The electrode slice is designed as a petal shape, with HTZ's logo at the bottom. The overall design follows the middle course.

At the bottom, there are regular product identifications, and relevant parameters such as the maximum weighing weight that can display good knowledge; Below is the battery compartment, which is powered by 4 AAA batteries. It is very convenient for users to replace it.

Yunkangbao Mate also uses a white panel design. The electrode design is more formal than that of Goodknowledge, and the logo is embedded in the center. The sense of integration is better than that of Goodknowledge, mainly because Yunkangbao's logo is more low-key.

At the bottom, the layout is similar to that of Goodknowledge. The same is the product label and battery compartment, and the same is the use of four AAA batteries for power supply. The difference from Goodknowledge is that the battery compartment is arranged above the label.

In contrast, the Lexin S7 is much more "prominent". It uses a black panel design. Although the area is no different from that of Yunkangbao and Hitizhi, it can be seen that the part covered by the electrode is slightly smaller than the first two. The logo is similar to Yunkangbao and is directly embedded in the center.

There is nothing special about the design of the bottom, which is also the label and the battery compartment. But because the overall design adopts the oval design, it doesn't look as neat as HTK or Yunkangbao.

In terms of the three dimensions, Hitizhi M1 is 320x320x23mm, Yunkangbao Mate is 310x310x25mm, and Lexin S7 is 352x330x29mm. In contrast, Lexin S7 has the largest volume among the three. Haotizhi M1 has the thinnest thickness, but its weight is 2kg as the largest Lexin S7, while Yunkangbao Mate is 1.8kg. By comprehensive comparison, Yunkangbao Mate has the best volume and weight control.

Function comparison

Since it is an intelligent fat scale, apps are indispensable. Tsinghua Tongfang's HTZ M1 supporting app uses green as the main color, and basically functions around the body fat scale. Naturally, there are corresponding in-depth analysis, evaluation details and other status displays. Users can also see their own weight and body fat, and make specific weight loss and fat reduction adjustments according to the actual situation.

The app of Yunkangbao Mate is similar in design, but the main color is changed to blue. At the same time, because the heart rate sensor is added, the data displayed will be more comprehensive. The other thing that I am particularly pleased about is that all data of Yunkangbao can be synchronized to iOS's own "Health", QQ Health, Keep and other related programs through the app, which is particularly convenient.

Lexin's app is a little different. It directly uses Lexin exercise to take over the data of the body fat scale, so we can see that the app is more focused on step counting and aerobic exercise than on body fat and weight. Of course, there will still be details about body fat and weight, but not as detailed and focused as Good Body Knowledge or Yunkangbao.

Of course, as a body fat scale, it is the most important thing to correctly reflect the user's weight and body fat. The author personally tested three products at almost the same time, and the test results are as above. From the test data, Yunkangbao Mate's values were completely consistent in the three measurements, and Lexin's performance was also good, but the performance of Haotizhi was somewhat unexpected. Not only did the data change in the three tests, but also the data were quite different from the other two (The author successfully lost 5kg!) In this respect, M1 can be said to fail.

In terms of measurement accuracy, Yunkangbao is better than the other two for a reason, because at the beginning of user settings, the app will require users to describe their waist hip ratio and body shape according to their own conditions, so that the app can adjust the algorithm for different users, better measure weight and body fat, which is a major advantage of Yunkangbao Mate.

Service comparison

In addition to the measurement of body fat and weight, the three are also different in other service parts. For example, in app connection, only Yunkangbao Mate currently supports direct connection through WeChat applet. Search for "Yunkangbao Body Fat Measurement" and quickly log in with WeChat. Then you can directly measure data on the scale, which is quite convenient for users who do not like to bind apps or occasionally use them. However, Lexin S7, which used to provide WeChat services, has now changed to a mandatory app, which will make it easier to use Yunkangbao.

Another problem is that the tested Lexin S7 WiFi version can only transmit data through WiFi, and the other two models can quickly provide measurement results through Bluetooth. In actual use, if there is no WiFi, the usability of Lexin S7 will be much lower. And I don't know if it's the problem of the author's RP. After using the Lexin S7 for several times, it can't be configured with WiFi, so I have to ask the after-sales service to deal with it.

tail

In this horizontal review, although Tsinghua Tongfang, Yunkangbao and Lexin are all products that have passed the medical device certification, there is a big gap in the actual experience. In the connection with app/WeChat, the experience of Otiski and Yunkangbao is good, but the measurement result of Otiski is far from the other two products; From the measurement results, Lexin S7 and Yunkangbao are both convincing, but the WiFi version can only transmit data through WiFi and apps, which is inconvenient to use in some cases, which greatly reduces the user experience.

To sum up, Yunkangbao Mate has the highest comprehensive quality among the three. The user experience and measurement results are satisfactory. The direct use of WeChat applet is icing on the cake. Adjusting the algorithm according to the user's shape is also one of the advantages, which is worth buying.
