The Coaching OS
for Volleyball
Track rotations, substitutions, stats, and match flow in one simple sideline app built for real coaches.
Coaches testing CourtOS this season
Built for the chaos of live coaching
Coaching a live match means managing a lot at once. Your tools should reduce the load, not add to it.
Paper scorebooks are slow
Writing rotations, subs, and point sequences mid-match means your eyes are off the court — and the details still end up incomplete.
Rotation tracking gets messy
Keeping track of who's where, which rotation you're in, and when the libero switches adds mental load you can't afford during a close set.
Existing apps are too complex
Most volleyball stat tools are built for programs with dedicated staff — not a single coach managing everything from a folding chair on the sideline.
Everything coaches need during a match
No unnecessary complexity. No stat crew required. Just the tools you actually use when the score is close and the clock is running.
Live Match Tracking
Record points, sideouts, and timeouts as they happen. Every play logged in real time — no pen, no clipboard, no lag.
Rotation Management
See your full lineup at a glance. CourtOS advances the rotation automatically with each serve so you never lose track mid-set.
Auto Subs & Libero Tracking
Define your substitution rules once. CourtOS alerts you when it's time to swap and tracks libero replacements automatically.
Simple Stats
Track kills, errors, aces, digs, and blocks without a full stats crew. Designed for one coach doing it all from the sideline.
Point Mapping
See where you win and lose points on a court visualization after each set. Spot patterns while the game is still fresh.
Match History
Every rotation, sub, and set score from every match — searchable and ready to review before the next one.
Help shape CourtOS before launch
We're inviting a small group of volleyball coaches to test CourtOS during real practices, scrimmages, and tournaments.
Designed with real volleyball coaches
CourtOS is being built from real sideline feedback, not generic stat-tracking templates.
I just need something that tracks rotations and subs without getting in my way during a match.
Built for fast match decisions
Every interaction is designed to take less than a second. CourtOS gets out of the way so you can coach.
Designed for youth and club volleyball
Built around real youth and club programs — not adapted from professional or college systems.
Tested around real coaching workflows
Shaped by actual sideline feedback from coaches running practices, scrimmages, and tournaments.
