LineupLock

LineupLock is a mobile + web app for volleyball coaches that eliminates the most common game-day mess: incorrect rotations, missed subs, and confusion when switching setters, running 6-2/5-1, or tracking libero replacements. You set your roster, choose your system, and the app generates rotation cards, substitution prompts, and a simple “who should be where right now” view for each rally. It’s not trying to be full match analytics; it’s a practical sideline tool that reduces errors and saves time for volunteer coaches and understaffed programs. It also produces printable rotation sheets for officials’ tables and a shareable link for assistants. If you want stats, use your existing tools—LineupLock focuses on getting the right players in the right spots, consistently, under pressure.
