Tennis Game Scheduler

I'm a amatue tennis player. Whenever I played a tennis, I needed this kind of tool. I found several apps but those are not free and need a registration. So, I made this app by myself. Main features: * Generation of game schedules automatically * Editing of the game schedules * Showing of rankings automatically Remarks: * Play type to support: Both double and single * Maximum players: 16, minimum players: 5 * Game scheduling method: Hanul-AA-2021 and Hanul-AB-2021 * Seed assignment to avoid unbalancing of matching * Matching from two groups. Divide the players into two groups, and choose one player from each group to form a team. * Automatic calculation of rankings by assign points of all games Feel free to use it and welcome to your feedback.
