Which sleep tracker? Watches aren't accurate.

Accurate or precise?

Scales can be useful even if not accurate, so long as they are reasonably precise. Same for sleep tracking watches.

The whoop. I recently compared it with an actual sleep apnea test and the REM is not accurate at all. But it is interesting to see tendencies (drinking alcohol really messes up with your sleep, winter increases your REM, etc.)

Whoop is definitely not accurate for sleep data, but it's great for exercise and there's certainly value in seeing trends.

I use Withings (a pad that you put under your mattress) because I can't stand wearing anything when I sleep. Seems ok according to this analysis:
