  • Do not use it in high-temperature places such as saunas and steam rooms. The high-temperature environment will significantly increase the probability of water entering the watch.


1. Can not search the Bluetooth of the device in the APP.

It is possible that when you connected the device, you linked directly to the Bluetooth of the mobile phone system. Therefore, the connected device needs to be connected to the APP and not join in the phone settings. If the Bluetooth has bound in the phone settings, please unbind in the phone settings first, and then enter the APP to search for Bluetooth to bound. Note: A Bluetooth pairing request will pop up when the watch has connected to the iOS system. You need to click Allow pairing to connect the device normally.

2. The APP can’t synchronize the data of the smartwatch

The Bluetooth wireless connection may have signal interference and other reasons, which may cause the link or data synchronization time to be too long. In addition, the Bluetooth of some mobile phones may occasionally be abnormal when starting up. Therefore, it is better to restart the phone’s Bluetooth before pairing.

3. The watch cannot be charged

Please make sure that the positive and negative poles of the charging port are not reversed and that the charger is powered on; when the battery of the watch is too low, there will be a period of battery pre-charging time.

4. The time of the watch is not accurate

When the device is fully charged after a dead battery or has not been used for a long time, there may be errors in the time. However, as long as the APP is connected, the time will be automatically synchronized.

5. Heart rate detection will fail or be inaccurate

These conditions may be caused by non-standard wearing methods, such as light leakage due to incomplete fit to the skin, movement of the watch on the skin, wearing the watch too tightly, raising the arm, and making a fist that affects the blood circulation, Etc. These conditions may affect the heart rate measurement. The correct measurement method requires laying your arms flat, relaxing your body, and keeping it still while ensuring that the watch is close to your wrist.

6. The number of steps recorded by the watch is inaccurate or wrong

The following conditions may cause it:

• The arm swing amplitude, frequency, and law of the arm swing will have a particular impact on the step count. In addition, the accuracy of the watch’s step count is related to the walking posture, walking habits, walking speed, walking continuity, and road conditions.
• Please fill in various information correctly in the APP and synchronize it to the watch, including gender, height, weight, age, all of which will affect the step counting algorithm.
• In daily life, we often shake our arms or bodies. In some scenes, the shaking is regular, and the watch will misjudge it as walking.
• If only a few steps are taken when counting steps and the movement is not continuous, the watch may not record.
• The watch does not have a GPS positioning function, so there will be a specific error in step counting in sports mode.

7. Instructions on APP sync data

After the device is connected to the APP, the data can be synchronized to the APP for display. When connected to the APP, the APP will automatically synchronize all the device data once; pulling it down on the APP homepage will also synchronize the data.
Note: The device saves data every 15 minutes; the data displayed on the home page of the APP is the real-time data of the device, and the historical data of the APP is the data saved by the device every 15 minutes.
