All-day activity tracking: The smart bracelet can not only track your heart rate and sleep status, but also track your daily activities, such as steps, distance, calories burned and minutes you take, etc., to help you better understand your fitness level. Blood pressure and heart rate: The bracelet uses a high-performance CPU to monitor blood pressure and heart rate, so that you can know your physical condition at any time. But these data will not be used for medical treatment. Sleep Monitor and SMS Call Reminder: After connecting the application, the tracker will automatically track your sleep time, sleep stage, and analyze sleep quality data. If your mobile phone receives a phone call, SMS or SNS, it will vibrate to remind you, and you can refuse the phone on the bracelet. Sedentary reminder: automatically record your daily calorie consumption to help you adjust your diet. Set it on the application for a period of time, and then the tracker will shock the sedentary reminder, which is a practical function for office supplies to improve health. Long-lasting battery and gift: it can be used for up to 5 days and fully charged. Bright color soft strap and fashionable color screen are excellent gifts for sports or fitness enthusiasts, teenagers, birthdays and Christmas. Note: Make sure to insert the USB charging port in the correct way. If it is not charged, turn the USB to the other face and plug it in again.
