SidelineLive brings league management and live scoring together in one platform built for flag football. Manage teams, rosters, schedules, and tournaments, then track scores, clocks, possession, timeouts, and penalties from the sideline. Fans follow through shareable spectator pages, while organizers monitor multiple fields in one live view. Custom division rules, pool play, standings, and seeded brackets connect the entire journey from season setup to the final whistle.
