The hand timer in the application can be used when you want to put someone on the clock.
Tournaments use timers when a player calls to put another player "on the clock". The player is given a certain amount of time to make a decision. If they do not take action by the time the timer expires, their hand is folded.
You can bring up the hand timer the following ways:
When you bring up the timer, it will come up with one minute remaining. You can adjust the time remaining with the arrow buttons. Once you start the timer, it will begin to count down.
When the timer reaches five seconds, it will turn yellow and begin to beep. When it reaches zero, it will stop and turn red.
