Variable countdown stopwatch/timer for workouts?

[john dough]

I have an iPhone but really would prefer a stand-alone device, where if it were to get beaten up, I would not be as concerned.

I was googling around and found this:

I think that it will do it for me. In a few weeks, I will be doing my workouts outside and having this device will help with workouts (work hard/rest/work hard/rest) without having to look at my watch.

I may get the app anyway as it looks like a good tool otherwise.
