Start the stopwatch instantly, then turn it into a timer. Most timers are inaccurate because it takes 5 to 30 seconds to set the timer while time slips away. With StartWatch, you start the timer like a stopwatch, then you can take as much time as you need to set the alarm. Features Include: Run multiple stopwatches and timers. Convert a stopwatch to a timer and back to a stopwatch. Stopwatch continues to count after the timer is finished. Set a timer based on the time the stopwatch began, or the current time. Change a timer without losing the start time. Customize how the StartWatch is displayed. For example you can choose to show in weeks, days, or years. History - Undo an accidentally stopped StartWatch or change the start time of any event. Markers - Mark a moment in time on a running StartWatch.
