Or a use Garmin watch, and get even more metrics. It's like strapping the elastic stack to your body.

Yeah, I used to have a Hello Sense. I've been using Apple Watches for years, but I never wanted to install a 3rd party app for sleep tracking, nor have to charge during the day instead of at night.

Now I just wear a Garmin Forerunner 945. It seems like it must be more accurate than this Oura thing, though i know almost nothing about it.

Does the Apple Watch do sleep tracking out of the box now? I was one of the 5 people who bought a Microsoft Band, and I really enjoyed the sleep tracking features. I still haven't pulled the trigger on an Apple Watch since switching to and iPhone because it (used to?) lack sleep tracking as a feature.

No. It still is intended to charge overnight. Apple store sells other sleep tracking products at this time.

It charges fast enough that you can wear it almost 24/7 if you plan ahead and charge for a bit in the morning and at night

There are sleep tracking apps that integrate with the health app, but I tried two of them (sleep++ and pillow) and I found them to be very inaccurate.

It does, I like AutoSleep and SleepWatch to track my sleep, and as a fellow poster added, you can get by with just a few minutes of charging in the morning and night

I have both. Dislike wearing Apple Watch in the bed since it turns on randomly and it's bulky. The Oura doesn't feel much larger than a wedding band and it's lighter.

Turn on theater mode and the display only activates when you press the crown. The battery also lasts longer!

For myself, it comes down to form factor. I don't like wearing watches, but I am OK with wearing rings.
