Why does the Android phone APP need to turn on GPS (location information) to search for the device?


Because the system Bluetooth scanning after 6.0 needs to apply for location related permissions to support some Bluetooth functions, such as discovering nearby bracelets. This is the permission that must be used during development.

The bracelet obtains the time from the phone via Bluetooth. As long as your phone and the bracelet are successfully bound, the time of the bracelet will be automatically updated and synchronized with the phone time.



Can the bracelet record sleep during the day?


Daytime sleep is not currently recorded.


Why do I wear a bracelet to sleep, sometimes there is no sleep data?


  1. The bracelet currently does not record daytime sleep, including naps


  1. The sleep data of the night before is all after getting up the next morning, take a few steps to move your arms, let the bracelet know that you are up, the bracelet will exit the sleep mode, and then the sleep data can be synchronized. Sleep data is displayed after 7:30.

When does the bracelet start recording night sleep? Will it be recognized as sleep when the handle ring is placed on the table?


Sleep detection starts at 9:00 PM. The bracelet can distinguish between resting and sleeping.



Why does the blood pressure value deviate from the sphygmomanometer?


The deviation of the measured value of the wristband and the blood pressure meter is determined by many factors. The measurement position of the blood pressure meter is in the brachial artery, and the measurement position of the wristband is in the two main branches of the arterioles. Normally, the measured value of aortic blood pressure and The blood pressure measurement of arterioles will vary by three to forty; if you use a wristband and a sphygmomanometer to measure at the same time, because the blood flowing in the artery is eccentric, the sphygmomanometer measures the band below the center of your elbow. Under pressure state, blood cannot flow smoothly to the lower arterial branches temporarily; increased vascular tension will cause greater deviation of upper and lower blood pressure measurements。


Why does the bracelet temperature deviate from what I measured?


  1. The temperature of the bracelet is calculated based on mercury data, please do not compare other products.


  1. The wristband measures the skin temperature of the wrist, which has a slight deviation from the armpit temperature.


  1. Please take the measurement after wearing the bracelet for 10 minutes to eliminate the reason that the temperature transmission is not timely due to insufficient wearing time.


  1. The skin temperature measured by the bracelet is greatly affected by the surrounding environment. If the temperature is too high or the temperature is too low, the deviation from the actual body temperature will be slightly larger, please do not use this as a reference.


  1. The measurement results are for reference only, not as a basis for diagnosis and treatment.


If the difference between the bracelet temperature and the mercury body temperature exceeds 1 degree, please contact the dealer for after-sales treatment.


Why the APP can't use English and can only display Chinese


Please ensure that the current language of your mobile phone system is English, and the APP will adapt the display according to your system language. The bracelet will be consistent with the APP. If the APP language bracelet does not support it, it will display English by default. If you still cannot display English, please provide your phone model and phone system version. And with APP interface picture, setting language and region picture



Why is blood pressure and blood oxygen not measured regularly?


Currently, the bracelet does not support timing measurement of blood pressure and blood oxygen, you can choose to measure it manually.
