I'd like something like this http://www.keithv.com/software/stopwatch/
but with an alarm that goes off as you approach the count down zero time or once it is reached. Then at that point, you can simply press reset and start back at the original count down. The above app is perfect minus no sound ability.
I'm mainly looking for a count down but those are mostly built into stop watch apps. It should have a reset button so I don't have to reconfigure the original count down time again.
