Volleyball Lineup Tracker is a handy utility for volleyball coaches to use before and during matches. Create multiple rosters including scheduled substitutions and optional libero(s). Track possession, score, time-outs, substitutions, libero swaps, and rotations during a set. Includes support for rally or sideout scoring, side switches, libero serving, and non-standard start/end scores. Replaces and far exceeds the functionality of a plastic rotation locator costing $8-10...it even reminds you when you have scheduled substitutions and liberos moving to the front row! Made by volleyball coaches for volleyball coaches – we use it ourselves for every match. "Used the app for about 6 matches now and I love it. Thank you for this as it is exactly what I have been needing. A feature that I didn't really notice right away and have come to love is the 'undo' screen. A great tool when you have to prove where the score keeper made a mistake!" - Coach Scott Please click on Reviews (select "All Versions") to see other reviews of VBLT from coaches like you.
