As it happens I don't track my exercising either, I go to gym and do exercises simply because I know it's good for me and that as an IT worker my job is too sedentary. Maybe if I was working towards a competitive goal (run a marathon or do a triathlon) I would track as iterative improvement would be necessary but I'm not so I don't. Equally I don't have competitive goals for my sleep cycles.

I agree with you in principle but as someone with bad habits (not getting enough sleep) I think the watch can help as a guide to change those habits and live a healthier and longer life.

For whatever it's worth, there are some studies that suggest that even if you work out every day, sitting for a consecutive 8 hours a day will still shorten your lifespan. So a watch might remind you that you've been sitting to long and to take a 5 minute stroll.

fwiw, Apple watch does actually remind you to stand up and walk around once an hour if you haven't. I've actually found it a nice reminder. I can tell when i get the buzz that yeah i've been sitting too long I should get up and walk around.
