If you happen to meet the internet while using your mobile phone, once you open WeChat, the data of WeChat movement will be automatically updated. Wechat campaign is a public account similar to the step-counting database developed by Tencent. Users can check the number of steps they walk every day by paying attention to the official WeChat account of WeChat Sports, and at the same time, they can PK or like sports with other users.

The built-in vibration sensors or auxiliary processors of mobile phones, such as gyroscopes and gravity sensors, will store data according to the vibration frequency of these devices.
Simply put, when people walk, the center of gravity moves up and down a little bit, and sensors and collaborators perceive this movement of the center of gravity and count it.
