Pickleball Scoring with Leaderboard

Could be used for Tennis, Ping Pong, Racquetball, or just about any other singles or doubles type sports. It offers a player database, singles and double format game manager, and reflects a leaderboard of best game averages, wins, and total points. It was created via the free version of Glide and is my second endeavor with Glide apps, and much simpler than my original effort.

As I blindly feel my way through creating with Glide; I am hesitant as to whether the best methods are used, therefore, if there are any suggestions, please advise
