Web App, allowing users to add each other, create game sessions, record and see results of games.

Hello there, so currently, I have this google sheet, which allows players to input their scores after each game, and then the google sheet generates automatic graphs and statistics, to show the progress between the players. I want to expand this, by creating a web app, which would allow people to sign in, add friends, and create game sessions with friends, that would have the functions of that google sheet. I have some ideas in mind, and I want to discuss further, feel free to message me for more details! Open to negotiations
