6. Sleep monitor
You need to wear the watch at night and the watch will monitor your
entire sleep schedule and analyse the quality of your sleep according to
your nocturnal movements.
7. Heart Rate detection
Manual detection: Enter the application, click "Monitor" to monitor in the
health interface and the measurement process lasts for 2 minutes. Since
the App can't carry out measurements of heart rate in the same time,
don't switch the interface when measuring your heart rate. When the
interface is switched, the watch will stop measuring. The figure below
shows the heart rate page.
