The Williams Penalty Card app gives you all NFHS signals, penalties, and penalty yardage. The app is a digital version of the front and back images of the Williams Penalty Card currently available to the public at penaltycard.com. The app also includes a searchable penalty summary list that contains example penalties and yardage filters. For the card images, touching any signal displays a detail view with signal information in a more readable format. When looking at the summary list, each penalty has an information icon that displays a detail page with foul text, signal number or numbers if more than one signal is required, penalty yardage and rule book references. If multiple signals are required a scroll view allows the user to swipe left or right to see the signals.
