■ Generate pairings automatically
Just enter your player count and number of courts, and PairGen builds fair, rotating pairings and matchups for you.

・Adjust pairing balance with skill level settings

・Mixed doubles support

■ Score tracking built in
Once pairings are generated, keep scoring right in the same app.
・Simple tap-to-score input

■ Rest and player management
・Track playing / resting status per player, so last-minute absences or additions are no problem
・Manage players by name (no need to remember numbers)
・Add player photos
・Save and load groups of players ("today's members")
・Player list shows a dot indicating who is currently in a match — tap it to "pin" a player for top priority in the next combination

■ Share your data
・Share a session (players and combination) with another device via AirDrop
・Email match results directly from the app

Start a server from the Game tab to let other phones/tablets on the same Wi-Fi view the combination and player list, and perform some actions, from a web browser. Check progress from anywhere in the venue.

■ Great for
・Deciding practice matchups at badminton/tennis clubs
・Assigning courts and tracking scores at tournaments or practice sessions
・Handling last-minute player changes with flexible rotation
