LineupLock

LineupLock is a mobile + web app for handball coaches and team managers to plan, share, and lock matchday lineups and rotations without the usual WhatsApp confusion. Coaches build a match plan (starting seven, substitutions, defensive/offensive specialists, penalty shooters) and publish it as a clean, printable and shareable “match card.” Players get role-specific notifications (e.g., “You’re first pivot sub at 12:00–18:00”) and can confirm availability and jersey numbers. During the match, a simple bench view tracks who is on court, who’s next, and time-based rotation reminders—no advanced stats, no video analysis, just operational clarity. It also stores templates per opponent and competition rules (roster size, timeout limits) to reduce last-minute mistakes. This is a traditional app with a small AI assist for auto-suggesting rotations from past templates and availability.
