This is a full screen stop watch. I frequently "time" my Stat students during different activities/tests/surveys, etc. I've found timing them on the classroom clocks or with a cell phone stop watch to sometimes be tedious. This stop watch is easy to see, can be used as "stopwatch" or as a "count down". It also "bings" when the countdown reaches zero (if your speakers are on).
