This app helps you to umpire (referee) Eightball pool matches (using World Eightball Pool Federation rules).
The main feature is a 60 second timer, that can provide a warning at 30 seconds.
It shows how to correctly rack the balls before the frame starts, and can (optionally) assist in making the correct ruling following a break or time foul.
The entire main area of the screen can be clicked to reset the timer, which vibrates to indicate that the timer has been reset. This makes it easy to time shots without having to look away from the table!
Includes a timeout button and various settings.
This app can also be used from an Android Wear device.
