Tournament management for pool

Run the room from your pocket.

Headstring keeps the bracket honest, works out which match goes on the table that just freed up, and tells a player at the bar that they are up on table three. One person, one phone, a room full of players.

• Brackets that hold up

  Single and double elimination with byes, handicapped races, forfeits and late entries. Every result reversible, because somebody always taps the wrong number.

• Nobody misses their match

  A push when you are up, and another ten minutes before, worked out from how long tonight's matches have actually been taking.

• The room can watch

  A board for the TV, a display for the table, and a link that still works at midnight for anyone following along.
