Tennis Scoring App

Tennis Scoring App — a custom-built web application developed by Crosswell for a professional tennis player. The umpire only tracks key events — points, serves, and errors — while the app automatically calculates full match statistics: serve percentages, break points, double faults, and more. A separate scoreboard page updates live via WebSocket and can be streamed during matches. Supports champion tie-breaks, no-advantage rules, rollback of last points, and match joining via a unique link. Mobile-ready and fully customizable for tournament branding.
