In regular stopwatch mode WMStopWatch shows:
* the time you started counting
* the current time
* total elapsed time (running total)

With countdown mode enabled you can input any combination of hours, minutes and/or seconds. Once you start the countdown it displays the start time, the projected stop time, and the total time left. When the countdown reaches the projected stop time, you are alerted with a pop up and a tone.

Unless you stop the counter, it will continue counting. The "remaining time" display will turn into "Overage", and the tone will continue to sound every 2 seconds to alert you. Once stopped, the total time actually elapsed is displayed. (This is great if you need to know exactly how far you went over!)

The sound can be toggled on and off on the main screen so you can hush the alert at any time.
