A smart bracelet is a wearable smart device. Through the smart bracelet, users can record real-time data such as exercise, sleep, and some diets in daily life, and synchronize these data with mobile phones on an equal footing, thus playing a role in guiding healthy life through data.

The bracelet was supposed to be an ornament, but it was only before intelligent technology pushed its door open. Now it is trying to record a series of related data such as users' fitness effect, sleep quality, diet arrangement and habits, and can synchronize these data to users' mobile terminal devices. Terminal equipment can give relevant suggestions according to its own "analysis function" and play a role in guiding healthy life through data. It can be said that it is an advanced pedometer, which has the general functions of step counting and distance measurement, heat and fat, as well as special functions such as sleep monitoring, advanced waterproof, Bluetooth 4.0 data transmission and fatigue reminder.
