The Shot Clock
CSI-ready shot timing on iPhone and iPad — extensions, break timers, and player tracking for league or professional play.
How it works
Set up the clocks you need, start the timer, and keep every rack on schedule.
Clock settings
Whether you create your own configuration or use the defaults, selecting a clock shows every setting. Edit anytime.
Start the Clock takes you into the running timer view.
Running clock
Break — Reset extension trackers and start the clock for a new rack (uses the Break Timer value if set).
Ext — Extension called. Adds the Extension value and assigns it to the active player (one per rack).
@ N sec — Pause with N seconds remaining (CSI league play when the player is down on the shot).
Pause / Resume — Hold the countdown and continue when ready.
Active Player — Toggle between players so extensions are recorded correctly.
Player Manager — Set player names for the Timer view; names save with the configuration.
