The Simple Counter App is designed to help a person count anything they need.
The default number is set to 0.
The Left side button with the arrow pointed up and a plus sign on the bottom of it adds a number to the count.
The Right side button with the arrow pointed down and a minus sign on the top of it subracts a number from the count.
The bottom button is purposly shaded in a darker color because its used to clear the number entry back to a zero count.
