GlobalRSC
A live, portable rating for every racket-sport player.
GlobalRSC gives every player a visible sporting identity — ratings, match history, and progress built from real matches across tennis, pickleball, and table tennis.
- Live sport-specific ratings, rankings, results, and progress — tennis (GTR), pickleball (GPR), and table tennis (GTTR).
- A public player profile you control — shareable ratings, match history, and results that preserve your local sporting recognition.
- One platform for clubs to run challenges, ladders, leagues, tournaments, training, and community events.

Common questions
Yes — free during beta for clubs of any size. When paid plans launch, small clubs (up to 50 active members) will stay free forever. No credit card required to start.
No. You can set up ladders and record matches with just a handful of members in the app. Players join on their own time — you don't need everyone on board before your first match goes up.
Most clubs are live in under 5 minutes. Add your members, give each one a starting rating, and record your first match. We're here to help — email us and we'll walk you through it.
Only members you approve can see your club's matches and ratings. Public leaderboards are opt-in per player. We never sell your data.
Drop us a line — we reply within 24 hours. During beta we treat every founding club as a partner and respond personally.
