Pool Shot Clock for iPhone

Pool shot clock to use for pool matches, tournaments and practice.
Choose either the "15 only" button to only use the 15 second shot clock timer or the "45 only" button to only use the 45 second shot timer.
To use the shot timer simply tap the start button to start the shot clock timer then the stop button to stop the timer and then the reset button that you've selected to use.
Once the shock clock timer reaches 5 seconds remaining there be audio alerts from 5 seconds to 0 seconds.
During play the stop then reset button should be pressed as soon as the 'in play' player strikes the cueball and the start button should be pressed once all balls have stopped moving.
The extension buttons will add a 15 second extension to the shot clock and should be used once per player per frame. Once the extension button has been used for either player then it will disappear and will only reappear once the frame button is pressed.
You can clear everything back to default by pressing reset all.
