The watch and the app use Bluetooth for data and control communication. When a user starts a sport (such as outdoor running) on the App, the user needs to use the positioning function to obtain the user's location information, calculate the user's movement distance, and draw the user's movement trajectory. Users can turn off the screen of the mobile phone and put it in a pocket, arm bag or waist bag, and can listen to songs or make voice calls (answer, reject, hang up) at the same time during exercise. Through the watch, the user conveniently receives notifications, controls the movement process (pause, resume, stop) and music playback (eg pause, resume, previous, next).
Users can use all features of the app without registering and logging in, and the stored data will be cleared when they decide to leave.
