It is a Apple Watch tool to help a playing soccer player to quickly record the training scoreboard/performance for both home team and the away team.
All of the scoreboard's recording actions need to be done on the Watch side, and the Watch app is designed to be independent of the Phone app.
After the training is finished, the player can sync the latest data on the paired iPhone.
All scoreboard data can be save to the photo gallery as an image, and also be exported as a data file.
