Center Ref is a watch-first match-management app for soccer referees. The Apple Watch is the primary on-field interface — running clock, score, event log, stoppage time, and haptic period transitions; the iPhone companion handles pre-match setup and post-match review. For referees without an Apple Watch, Center Ref includes a full iPhone-only mode that runs the match on the phone alone.

Built for AYSO U6–U19 with full division presets (period structure, field size, offside rule, no-heading flag, mid-half quarter break), Center Ref also supports club soccer (recreational, travel, and select) and a Custom division for high-school and adult matches.

Center Ref has no user accounts and makes no network calls during a match. Match data lives locally on the referee's paired devices, with optional iCloud sync between the user's own iPhone and iPad through Apple's private CloudKit database — the data stays in the user's Apple ID account; Center Ref never sees it.
