1. Open the Yue Run Circle APP, enter the main interface and click "Start" to start running.
2. In the start-up interface, indoor and outdoor options will be displayed. If you run outdoors, you can choose to run indoors, because outdoor running is not stable enough by GPS positioning technology, and slow network positioning will cause problems.
3. After choosing to run indoors, click the "Start" button to fix the mobile phone on a certain part of the body, such as the arm, to ensure its parallel movement. Because the Yue Run Circle records the running process through the mobile phone sensor, the up-and-down movement of the mobile phone is minimized.
