• There is a more professional analysis in multiple modules such as exercise, heart rate, sleep, and stress
• Building high-performance optical sensors, high precision infrared wearable detection for wearing, measure heart rate/blood oxygen/blood pressure
• You can set a custom measurement time by connecting to the app. Measure and record heart rate/blood oxygen/blood pressure/pressure assessment data on time
• Calculate the number of steps based on human body movement patterns. The swing in different states will be automatically recognized
• Built in wireless charging chip IC for longer charging life. The built-in battery in the charging compartment can store power, can independently charge the device twice when fully charged, convenient to carry and use when going out
