Built a free app for running group badminton sessions

Not from the UK, but figured this crowd organizes club/casual sessions too: built an app for running one. Check players in, it auto-generates doubles rounds that rotate partners so the same four don't hold a court all evening. Scoring uses the real rules (21, win-by-2, cap 30, serve rotation, side changes), court diagram shows who serves next. Leaderboard + per-player stats after.

Works offline, free, no ads.

One-time post, won't bump it — happy to answer questions in the comments though.
