If it's just running, there's no need to buy it. If you want to see how long you have run, how many steps you have run, how far you have run, the track of running, etc., you have to buy it. In addition, the sports bracelet can also measure heartbeat, sleep quality and other information, and it is recommended to buy it if conditions permit.

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 the user's fitness effect, sleep quality, diet arrangement, habits and a series of related data, and can synchronize these data to the user's mobile terminal device.

Terminal equipment may 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.
