Sometimes there is no sleep data in the app,why?
  • Before you synchronize sleep data,please comfirm the steps in the smartband is 25 at least.If the steps is under 25,there will be no sleep data in your app.
  • Please do not restart your smartband while synchronizing data.If you restart your smartband,your data will be erased,and there will be no data in your app.
the heart rate date is not accurate at all.
According to our analysis,if you wear your smartband too loosely,the data will be far away from your real heart rate data.
I touch the screen,but it seems not to work.
To awake the smartband,you need long press or slide the screen,instead of touching.
