I use AutoSleep on Apple Watch 4. It is good at poking me after a few days of not sleeping enough with a message like: "You slept for 5:38 last night, and have a sleep debt of 12%". That's enough of a poke to get my sleep back on track. I've also used it to experiment a bit with how drinking at night affects my sleep. (noticeably!). I could do that with just how I feel, but the hard data is easier to correlate later.
