I want to know why I sleep badly
Smart rings track sleep without a watch on your wrist. Here's what they cost to own.
Can a smart ring track your sleep without a watch?
Yes. Rings from Oura and Samsung track sleep, heart rate and recovery for about a week per charge. Oura needs a monthly membership; Samsung's ring needs an Android phone.
In stores now
- Oura Ring 5
The Oura Ring 5 tracks sleep stages, heart rate, HRV and temperature; BGR rates its sleep analysis among the best.
- Samsung Galaxy Ring
The Galaxy Ring tracks sleep and health with no subscription.
Coming or still in demos
Nothing announced beyond what's in stores.
Why it's hard: How accurate ring sleep stages are compared with a sleep lab; we haven't read an independent study yet.
