Clock List

Config List View - Copyright of Rack Discipline USA, 2022

When you launch the application you'll be presented with a list of available Shot Clock configurations. You can create as many configurations as you need. Probably you only need one or two.


Like the example shown, maybe one for the Professionals (a 30 second clock with extensions) and another for League Play (45 seconds or longer).
Select the '+" symbol to add a new configuration with your own choices.

Clock Settings

Config View - Copyright of Rack Discipline USA, 2022

Whether you create your own configuration or use the defaults, when you select a clock all the settings are visible.


Select 'Edit' to change settings at anytime.
Select 'Players' to set up the player names that will be displayed in the Shot Clock view. This makes tracking extensions much easier when you use real names. The names are saved as part of the configuration.
'Start the Clock' does just that - and takes you to the next Screen (Below)

Break - Reset the extension trackers and start the clock for a new rack. This will start the clock using the 'Break Timer' value if set.


Start - Begin counting down the clock with standard 'Shot Timer' value.
Ext - Extension called. Add 'Extension' value to timer. This will assign an extension to the current player at the table. Only one extension per rack.
Resume - Resume countdown following a pause.
@ N sec - Pause the clock with 'Pause At' seconds remaining. This applies to CSI league play when the player is down on the shot.
Pause - Pause the clock where it is. Resume when ready.
Active Player - Toggle between players. Extension is recorded against the active player.
