Pickleball Scorebook is an offline scoring tool for pickleball players, club events, and everyday matches. It focuses on common match problems: forgotten doubles serve order, confusing score rotation, and missing post-match records. The app requires no login, no network connection, and no account registration. It does not collect or upload personal data. All matches, players, and statistics are stored locally on your device, so you can open it and start scoring right away. Key features include singles and doubles scoring, server and position rotation, game point and side-change reminders, common scoring templates, player win-rate statistics, match history review, and local player list management.
