I do wake up earlier, but that's the point with the app: It gives you the "stress" of not knowing if it is 10min forward or not, it should/would work.
It's not that I need it when I wake up, but in general. Even though I am awake for 2h I would not know the real time.
This is as serious as Jobs is about not allowing Flash.

I like the placebo effect thing though, but that only works with me thinking I got some LSD.
