>Apple Watch doesn’t natively, and even if it did, you still have to charge it at night

The way around that is to charge it earlier in the evening before bed - I do that and it lasts me easily until the following evening.

But it's a shame the device doesn't cover sleep natively.

It does sleep analysis natively. You just need to enable a bed time and it’ll track it.

You may like AutoSleep. It gets darn close to feeling native.
