Smart Bracelet M4 (aka Lefun M4) is a visual copy of the popular Xiaomi Mi Band 4 fitness bracelet and this is the only thing that unites them, since the Lefun craft is nothing more than a toy for children that can only emulate the popular functions of smart watches . The Smart Bracelet M4 (A Partner To Monitor Your Health) manual will allow you to find out the capabilities of the device, its configuration and appearance, and also answer the most asked questions regarding the performance of the gadget. Attention! Another dupe has gone on sale – Smart Bracelet M5
More details about the new product: Instructions for the Smart Bracelet M5
Equipment
The device comes in a box that is quite reminiscent of that of Xiaomi, and what’s interesting is that it shows exactly the Mi Band 4 with its proprietary dial, which, of course, is absent in the M4.
This is quite often used by scammers on all sorts of online platforms (OLX, Avito, etc.), having purchased Smart Bracelet M4 in bulk for pennies on Aliexpress, they sell them under the guise of original smart watches with an allegedly huge discount under the names Xiaomi Smart Band M4, Xiaomi Smart Bracelet M4, Smart Bracelet Band M4, although this device has nothing to do with Xiaomi.
Inside the box there is a capsule with a bracelet (can be of different colors), a charging cable and useless documentation in English and Chinese.
Connecting Smart Bracelet M4 to a smartphone
First of all, you need to make sure that the bracelet is charged. To do this, hold your finger on the touch key until the device turns on. If this does not happen, charge the bracelet.

After that, we connect it through the standard Lefun Health application, which is suitable for both this and previous generation bracelets.

Why doesn't Lefun Health see the bracelet?
Attention! Do not give the application unnecessary permissions, since their presence in the program is not justified and it is quite possible that they may be one of the loopholes for leaking your personal information.
What a smart Chinese fitness gadget can do
The manufacturer claims the following functions of the M4 smart bracelet:
- Displays the heart rate of the wearer of the bracelet in real time. In fact, these are some average heart rate values taken from the ceiling;
- Blood pressure measurement (also averaged fake data);
- Pedometer – it really works, the error is 5-10%;
- Sleep monitoring;
- Training mode;
- Calories burned;
- Reminder of activity (for example, you have been sitting on a chair for too long, and the bracelet will remind you that you need to walk);
- Time that can be customized;
- Alarm clock and more.

Key Features
As mentioned earlier, the Smart Bracelet M4 is nothing more than a toy and is only suitable as a watch for a child (or an adult).
Despite its supposedly rich functionality and the manufacturer’s promises, in fact, the device’s capabilities are extremely limited and will clearly not be enough for those who want something similar to the Xiaomi Mi Band 4, but cheaper.
The first thing I would like to note is that the bracelet does not have a touch screen, and all control is carried out by pressing a button located under the display (short press - goes to the next menu item, long press - confirms the action).
Pulse measurement
Unlike the original Mi Band 4, Smart Bracelet M4 does not measure heart rate, but only blinks with LEDs located on the back of the capsule and then displays a result close to the normal value.
In this case, it does not matter at all whether the bracelet is on your hand or just lying on the table - the pulse value will always be within the normal range.
Pressure measurement
As with the heart rate, the pressure measurement on the Smart Bracelet M4 is also fake.
Measuring blood oxygen levels
Recently, fitness bracelets (for example, Honor Band 5) have begun to introduce technology for measuring oxygen levels in the blood, but if this is at least somehow measured, then this measurement is simply emulated.
Thus, all data obtained using bracelet “measurements” should be treated with great caution, not taken seriously and taken only as a fun game.
Notifications and incoming calls
Unlike the Mi Band 4, where you can configure the list of applications whose notifications will be displayed on the bracelet screen, the Smart Bracelet M4 has a very limited list (mainly Chinese programs) and only the application icon is displayed during a notification.
The same applies to an incoming call: a “handset” is displayed on the screen without information about the name of the caller.
Other options
Perhaps the only thing that works here is the time display and alarm clock. The time is automatically adjusted during synchronization with a smartphone, and the alarm clock is set through the Lefun Health application.
There is also a phone search function, but it only works if the bracelet is within the signal range of the smartphone’s Bluetooth module and they are connected to each other.
What application should I install on Android for M4?
To connect the M4 fitness bracelet to your smartphone, you need to download and install one of the mobile applications on your phone. FitPro can be downloaded from PlayMarket and AppStore.
FitPro is a proprietary application for the M4 fitness bracelet. After registration, the user gains access to his personal account and can enter the necessary information into the device’s memory: information about gender, age, height and weight. Next, the program included in the application will calculate the owner’s body mass index and the percentage of fat present in his body.
The highlight of FitPro is its habit tracker. Having set daily goals for himself, the owner of the gadget will activate the corresponding option and the application will regularly send motivational reminders to the user.
The FitPro mobile application is compatible with all portable devices (smart bracelet, smart watch, etc.) and allows the wearer of the gadget to control all functions of their body - monitor the quality and duration of dreams, measure pulse and blood pressure.
An alternative to FitPro is Yoho Sport. The application is completely Russified. After downloading YohoSport from Google Play or AppStore, the user must first charge the bracelet and make sure that both devices are turned on. Synchronization will occur automatically, immediately after Bluetooth is launched.
The application is able to remember the indicators and sort them taking into account the date and time of the diagnosis. The menu contains such items as “Pulse”, “Sleep quality control”, “Blood pressure”. The watch can be configured so that the display records not only incoming calls and messages, but also letters sent by social network users. Such as Facebook, Twitter and WeChat.
An important advantage of the Yoho Sport application is its intuitive interface and automatic synchronization with the phone after rebooting the fitness bracelet or gadget.
Alternatively, the connection can be made by scanning the QR code of the bracelet and using the attached instructions.
Most Android owners are new users. When attempting to sync a bracelet through a mobile app, they receive a message that the operation failed and do not know what to do next. In most cases, the reason for failure is the lack of experience in using gadgets, as well as insufficient awareness. By scanning the QR code, the user will save himself from unnecessary problems and worries.
Questions and answers
Can I swim while wearing the Smart Bracelet M4? Despite the declared protection against water, swimming in this device is highly not recommended, as there are known cases in which water got inside the case and the watch failed.
Can I answer a call using Smart Bracelet M4? No, you can neither answer the call nor accept the call. The screen only displays information about the incoming call.
How to set the time on Smart Bracelet M4? To do this, you need to connect from your smartphone through the Lefun Health application and the time will be automatically synchronized with your phone.
Where to buy a strap for Smart Bracelet M4? Straps from Xiaomi Mi Band 3 and Xiaomi Mi Smart Band 4 are suitable for this device. You can order them on the Aliexpress trading platform.
How to connect an M4 bracelet to your phone
To pair the M4 bracelet with your phone, you need to use the FitPro or Yoho Sport mobile application.
After installing the application on the phone and synchronizing the fitness bracelet with the phone, the user will not be able to immediately use the bracelet. First he must register in the application. During registration, the user will have to:
- Agree with all requests of the program (report your location, provide access to the camera and other personal information).
- Activate the “Install” option
- In the window that opens, select the “Find” command.
- Re-scan the QR code that appears on the display of the fitness bracelet.
Having completed all the steps, the user can begin to use all the capabilities that the device provides.
User actions when activating a smartwatch via Yoho Sport:
- opening the “Device” tab (the connection will start via the menu);
- activation of the connection. For the connection to succeed, the user must refresh the connection. As a result, the name of the smartwatch will appear on the display next to the “Connect” button.
By activating the “Connect” command by pressing the button, the user will launch the device. In the future, the bracelet will be switched to automatic operation mode, and the owner of the synchronized phone will be able to control all the functions of both devices.
conclusions
Be very careful when purchasing this device and do not confuse it with the original Mi Band 4. Smart Bracelet M4 and Xiaomi Mi Smart Band 4 are completely different devices in terms of capabilities and are in no way related to each other either by functionality or by manufacturer. By purchasing an M4, you run the risk of getting an ordinary wristwatch instead of a sports device, and it’s okay if it costs you a few dollars. It would be much more offensive to buy it at the price of the original Mi Band 4.
