Oura Ring 4: A Smart Ring for Sleep and Health

The Oura Ring 4 is a tracker ring from Oura, not Apple. Its case is entirely made of titanium, with sensors recessed into the inner surface. The ring monitors sleep, measures heart rate 24/7, and tracks changes in body temperature and blood oxygen saturation.

Suitable for those who want to track their sleep and recovery without wearing a watch. There's no need to charge the ring every night.
