A timer bar is added to the bottom of the combat tracker to time player's turns during combat, optionally ending the turn automatically when the timer runs out. The timer length can be customized per user, appearance of the timer can be changed, and settings are provided for playing alert sounds as well as notifying players when their turn is up next. Timers are only added to turns where at least one non-GM user has ownership over the currently acting combatant.
