Wearing devices are one of the hottest products at the moment. Just last year, there were tens of thousands of similar smart watch bracelets, and this year is no exception. One model after another was launched. We pay more attention to the appearance, function and data accuracy of these products. As a smart watch bracelet, the most important thing is to record movement data. Of course, it also includes some other small functions used, such as time display, incoming call, SMS reminder, and even heart rate detection. In this fierce wear market, it is also difficult to occupy a place, unless you have a cost-effective price on these bright features. Today, Lao Hu brings a smart bracelet that not only integrates the above bright features, but also has an ultra-low price. What kind of smart bracelet is it? With this curiosity, let's have a look.

For smart bracelet products, we pay more attention to the accuracy of the record and the use of the overall function, followed by the acceptance of the price. This time, Lao Hu experienced that this is a smart bracelet with intelligent heart rate test function launched by Shenzhen Evi Information Technology, which integrates large screen touch control and movement data sleep recording functions, Of course, there are some other small functions, such as long sitting reminder, incoming message, ringing fingers to cut songs, and so on. In addition to daily data viewing, the matching APP also has a voice robot that can view voice data at any time. However, the price is relatively friendly and only sells for 299 yuan. Next, whether it's that good or not.

Appearance details of i7 smart bracelet

The outer package is rectangular with an overall white design, while the front only has a simple brand logo. The product protection of hard sponge plays a very important role in the transportation process, which is simple and comfortable on the whole.

In terms of accessories, it is very simple to match them. The instruction manual and the charging cable are simple in function description, and even some functions are not explained. You can walk more carefully in the instruction manual, for example, it is easy to understand the overall function operation.

The i7 adopts an ultra-low power consumption memory display screen, which can almost be used in this type of smart bracelet. It not only has a good display effect, but also brings a more objective standby to the endurance. The 2.5D ultra-high reinforced glass is used for the screen appearance. The advantage is that there are slight scratches that can hardly be seen, while the disadvantage is that it will break when encountering hard objects. In touch control, we have not seen the use of button design before, but the use of capacitive touch screen to complete some functional operations. Compared with button design, touch is relatively convenient.

TPU medical grade material is used on the wrist strap, which is a common material used in our smart bracelet, providing good wearing comfort. The metal buckle design brings good fixation for wearing, which is not easy to fall off. In order to adapt to different hand sizes, nine holes are added, which can be worn according to the size of the hand, without worrying about the size of the hand.

The i7 is equipped with a dual core processor with ultra-low power consumption. One core is responsible for the processing of the screen and motion sensor, and the other core is responsible for the calculation of dynamic heart rate. There are two ways to test heart rate. You can select automatic and manual ways to detect heart rate, but the good is better than the bad. Turning on automatic will greatly reduce the endurance. Generally, it is 7 days, while turning off can achieve more than 10 days. Personally, I think it is better to turn off. If you want to test again, you can ensure the endurance.

The overall size is 39 * 31 * 8.4, which can be said to be the approximate size range of an ordinary watch, and this size can be worn by both men and women, without making people feel that the overall size is too large or too small to fit. For women, a variety of colors have been added, without feeling that black is too monotonous, and the weight of 30g is also very small, The wearer will not feel the weight. IP65 waterproof is adopted in the waterproof, which belongs to the scope of daily waterproof. For example, hand washing and rain will not let the bracelet enter the water and damage the internal parts.

Built in 100mAh polymer lithium battery, and the endurance depends on whether automatic heart rate detection is turned on or off, which depends on personal preferences. The magnetic charging design is adopted in the charging, and it is very convenient to draw automatically by aligning three contacts.

I7 smart bracelet client experience

In addition to viewing some simple data and settings on the smart bracelet, it can also be viewed and set on the matching client. Currently, it supports Android and iPhones above IOS 9, and is connected through Bluetooth 4.0 technology. The effective distance is about 10 meters. Next, let's see what different experience the client brings us.

When entering the client, the first step is to register. In addition to supporting mobile phone registration, third-party applications are supported for authorized login. Next, some personal information is filled in. Correct information is filled in effectively for movement calculation. Binding the bracelet is also very simple. Just open it and it will automatically search for the smart bracelet. Click to complete the binding operation.

On the setup page of i7, you can set some functions. For example, the upgrade process can be completed with one button without too much responsibility. It is also divided into independent firmware and heart rate upgrades. The operation is very simple.

There are 24 types of sports management on the sports data record, which can not only accurately record steps, but also view detailed sports data through clicking. Sleep adopts a fully automatic way, which will automatically test our overall sleep in a night to understand our sleep status. In addition to viewing on the client, you can also synchronously display the data of the number of exercise steps on the health app of the iphoen phone.

The main interface can also be selected and displayed in the way you like. In order to make the client more interactive, voice based queries have been added, which can not only query sports sleep data, but also carry out other queries, such as weather queries. At present, in addition to supporting the display of incoming calls and short messages, the application has also added information push, but it has less support. Only QQ and WeChat are relatively monotonous. In the later stage, the message push display can be added in an optional way.

I7 smart bracelet function experience

The i7 has a capacitive touch screen. In addition to the display of time and date, the main interface can directly see the display of sports data through the upward stroke. In the aerobic exercise interface, we can directly detect our heart rate, which is very intuitive.

Slide right is divided into three functions, namely, movement, message and function. Just slide to the corresponding function, and then slide up to select interface options. All operations are completed by sliding, which is as simple and convenient as our mobile phones.

In the function menu, the settings of most functions are integrated, such as the replacement of the dial, taking pictures, and turning on or off the automatic heart rate, which can be operated by long pressing. However, there are few patterns on the dial to be replaced, and there are only three options. I hope that more patterns can be replaced later. One function worth mentioning is music playing. It supports ring finger song switching. In the process of playing, you can switch songs through ring finger at will. This is a good opportunity to show off your skills in front of friends.

Aviva i7 has a fully automatic heart rate detection. It uses a leading heart rate sensor, which can detect heart rate from time to time. In the actual experience, individuals still choose the manual mode. After all, opening the fully automatic heart rate detection will greatly shorten the endurance time. What is commendable is that the heart rate range of fast and intense exercise will be fed back in different vibration ways, so that we can understand it more clearly.

Personally, I think the overall use of the i7 is pretty good. It's a pity that there is a slight lack of functions, which needs to be improved by subsequent engineers. For such smart bracelets, we prefer smart bracelets with screens. They can not only view time and date daily, but also facilitate us to view sports data in real time, rather than having to hold a mobile phone to view it. It feels more practical than those without screens. The basic functions we need can be seen in the Evian i7, including the popular sports and sleep data recording, heart rate detection, etc. In addition to these, we can also use the call and information display in daily use to avoid having to pull out the phone to check during driving, and also add some self safety. As a smart bracelet with heart rate detection, the current price is 299 yuan, which is relatively acceptable. Will you buy it?
