Soccer Team app help

Hello Thunkers, I have started build a Youth Soccer app. I want to be able to have the user/coach input their team roster and then be able to keep score of their match by having the roster of players and incrementing their individual goals to reflect the score vs opponent. I also want to be able to keep track of the players’ total goals for the season. So far I have built the sign up/in portion of the app, and created a page with list viewer for the coach to input the roster. I want to know what is the next best approach to creating a page to keep score of the game with the ability to keep score and save how many goals each player had for the season. My app is public and called “Soccer team” dont know if you all can search for it or how to share it. This is page to for the input of the team roster,
