PairGen - Badminton Doubles

About this app

PairGen makes it easy to run badminton and tennis doubles practice sessions — automatically generating fair pairings and tracking match scores, all in one app.

GENERATE PAIRINGS AUTOMATICALLY
Just enter your player count and number of courts, and PairGen builds fair, rotating pairings and matchups for you.
- Round mode: automatic rotation so everyone plays with different partners over time
- Free mode: freely edit and customize matchups yourself
- Fixed pairs: lock specific players together (for couples or skill-balanced teams)

SCORE TRACKING BUILT IN
Once pairings are generated, keep scoring right in the same app.
- Simple tap-to-score input
- Undo your last point
- Serve and end (court side) indicators
- Game-finished toggle and full score history

PLAYER MANAGEMENT
- Bulk-add players by typing comma-separated names
- Track playing / resting / absent status per player
- Set skill levels to help balance pairings and matchups
- Add player photos
- Save and load groups of players ("today's members")

COURT MANAGEMENT
- Add or remove courts, and fix skill levels per court

SHARE YOUR DATA
- Export a session (players, pairings, scores) to share with another device
- Email match results directly from the app

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

PairGen frees you from manually tracking "who's playing whom" and "which court is at what score," every single session.

Note: PairGen works fully offline — all data is stored on your device (except when you explicitly use the share/export feature).

What’s new

v1.2.20 changes since v1.2.19

- Fixed a bug where deleting a round (undo) could fail to correctly restore consecutive-game and absent-player game counts
- Round deletion is now limited to right after generating a round (it becomes unavailable once the next round is generated)
- Fixed opponent-matchup history being lost when the app restarts
- Fixed a bug where a newly generated round could fail to save if the app was closed shortly after
- Optimized the app to reduce its size
