Lose Count Once. That's All It Takes.

Fifth Sub or Sixth?

Three subs came in at once. You think that was five total. Maybe six. The coach thinks it was four. You're both wrong. And now you're arguing about it while the server is waiting.

DQ. Now What?

A player gets disqualified. Exceptional substitution rules kick in. But which rules? FIVB and USAV handle it differently. Your rulebook is in your bag. The coach is in your face.

Six Changes. One Dead Ball.

Both teams want to sub. Three in, three out. Each side. That's six changes to track, six limits to check, and zero time to do the math. Miss one and you've got a protest.

Every Sub. Every Limit. Every Ruleset.

Per-Set Limits by Ruleset

FIVB: 6 per set. USAV: 18 per set. NFHS: its own set of rules. The app tracks the count and blocks any sub that would exceed the limit. You never count in your head again.

Exceptional Subs, Handled

Player injured. Player disqualified. The exceptional sub rules kick in. and they're different under FIVB and USAV. The app knows which ruleset you picked. It applies the right rules, determines who can replace whom, and tells you if it counts against your limit.

Three Subs at Once? No Problem.

Batch entry. Record multiple subs between rallies without falling behind the pace of play. The app checks every one against the limits before recording.

Tap. Check. Done.

Pick Who's In. Pick Who's Out.

Tap the player leaving. Tap the player entering. The app checks the sub against your ruleset limits instantly.

Legal? Recorded. Illegal? Blocked.

Good sub? It's in. Bad sub? The app tells you why and won't let it through. No guessing. No second-guessing.

Questions? Answered.

FIVB: 6 per set per team. USAV: 18. NFHS has its own rules. Pick your ruleset at match setup and the app enforces the right limits. You never count.

Exceptional sub rules kick in automatically. The app knows your ruleset, determines who can replace the DQ'd player, and tells you whether it counts against your limit. No rulebook required.

Yes. Batch entry. Record three, four, six subs between rallies. The app checks every one against the limits before recording any of them.

Yes. Libero replacements are not subs. Different rules, different tracking. The app keeps them separate so you never accidentally burn a sub on a libero swap.

Your Head Is Not a Substitution Tracker.

Let the app count. Let the app enforce. You ref the match.
