Pool Shot Timer is designed to make it easier to time the shots in a game of pool.
The default setting is a 60 second countdown with a warning at 30 seconds but these can both be changed if required.
At the warning and when the timer runs out a chosen notification sound will play or you can use the built in speech option.
Accidentally closed the app? Not a problem, a notification will appear at the warning time and when the timer runs out. (Notifications must be enabled when prompted for this to work)
During the countdown, the option to call a 'Time Out' is enabled. From there you can continue the timer, start from the default time or just stop the timer.
