The Oura smart ring is entering its third generation, and now has an optical sensor that allows you to track the heart rate during all day long. Earlier versions of Oura allowed you to record your heart rate only at night.

The new generation smart ring doesn't look much different from the previous versions, on the outside. Inside, Oura managed to include several new hardware inside the small chassis, as pointed out by the Engadget website.


Users can now track heart rate and blood oxygenation during workouts. Temperature monitoring has also been improved, and the new device is much better at predicting when the menstruation of users will start, according to Oura.
