Although the sports bracelet is a tool for recording steps and sleeping, it also has the function of watching time. But when you wear a sports bracelet, there will be a psychological hint that you should increase the number of steps so that you can walk and run more unconsciously.

Although there are some deviations in the function of recording sleep, it can generally reflect the time and length of your sleep. You may think that you usually have something to record your sleep time, but you will clearly realize that my sleep is so regular when you look at the sleep records counted by the bracelet.

To sum up, I think the bracelet is quite useful.
