The Athlete Game Notebook is an APP for athletes. Athletes can view the weather overview of each city on the APPs home page, including weather conditions for the next seven days. You can memorize the competition information you participated in in the APP. After you memorize the information, you can view all the competition items you participated in on the competition list page, so that you can arrange the competition more reasonably and avoid missing the competition. At the same time, we also provide tools available during the competition. One is a scoreboard tool that can be used in ball games, and the other is a stopwatch tool that can be used in track and field games. Both tools can record game results. Users can click the "Game history" button on the home page to enter the "Game History" page to view their own game records.
