ClubLadder turns any iPhone into a court-side scoring assistant for clubs, group sessions, and ladder leagues — with live Elo ratings that update as each match is played.
ClubLadder is a free iOS app that lets a club admin manage players, events, and standings — while every member sees their position on the ladder in real time.
Every match updates every player's rating instantly. Ratings account for opponent strength — beating a higher-rated player is worth more.
Social rotating sessions, round robins, and single-elimination brackets. Pre-built schedules generate automatically when you pick participants.
Players install the app and enter a 6-character invite code. No email signup, no password. The admin gets full control; players get read access.
Manage players, import from a spreadsheet, view standings, and publish brackets — all from a browser, using a code generated by your phone.
Eric organizes 50+ players every week, rotating them across courts. ClubLadder tracks every result and produces a fair rating — even when not everyone plays everyone.
Maintain a rolling ladder where any member can challenge anyone above them. Ratings update after each challenge and the standings page shows exactly where everyone stands.
Run a single-elimination draw or a round-robin pool. Seeding is automatic from current ratings. Winners propagate through the bracket as each match is concluded.
