## What is V?

One of the few volleyball apps that covers 9-player, soft volleyball and coed formats.

"Am I tracking the rotation correctly?"
"Did I lose count of the substitutions?"
"It's my turn to officiate, but I've never done it before."

V-Ref is built for assistant referees who want to stop worrying. No officiating experience needed - you can use it the first day you're asked.


■ Supported formats

6-player (official rules) / 6-player coed / 9-player / 9-player (free rotation) / soft volleyball (4-player) / beach (2-player)

Very few apps cover 9-player, soft volleyball and coed formats in one place. It works as-is for recreational leagues, club teams and local tournaments.


■ Key features

· Real-time rotation tracking
  Enter jersey numbers and see the court layout at a glance. Catch rotation errors before they happen.

· Score & set management
  Tap to track both teams. Always know the current set and match status.

· Auto-counted substitutions & timeouts
  Remaining counts are tracked for you - no more mental math mid-match.

· Automatic set & match end detection
  Score conditions are checked automatically so you never miss an end-of-set moment.

· Position fault detection (6-player & coed)
  Automatically flags pre-serve position violations.

· Libero handling
  Substitution limits and front-row / serving-position warnings are covered.

· Match history & score sheet sharing
  Matches are recorded automatically. Review them later and share as a PDF.

· Achievements & stats
  The more you use it, the more you unlock.


■ New in version 1.4.0

· Save and reuse teams
  Team names and jersey numbers are saved when a match starts. Load them back with one tap next time - no more retyping. Mark the teams you use often as favorites and reorder them freely.

· Sanction records (warning, penalty, expulsion, disqualification)
  Record the cards shown by the first referee. The set and score at the time are kept with each entry and printed on the PDF score sheet.


■ Free to use

All core features are free. A one-time Remove Ads purchase is available if you prefer no ads.


■ Please note

This app assists the assistant referee's judgement and keeps your own record. It is not a replacement for an official score sheet. When submitting records for a tournament, follow the format required by the organizer.

Available in 12 languages.


For everyone who wants to referee with confidence.
