Oura Ring's Latest Update Identifies Your Chronotype

Oura Ring, a sleep tracker, is introducing a new feature that assigns users a chronotype based on body temperature, sleep-wake times, and physical activity over a three-month period. The feature tells users whether their body prefers mornings or evenings and how strong that affinity is, without the use of cute animals. The app also includes a body clock feature that tells users how well their sleeping habits align with an "optimal" sleep schedule. Oura is also adding support for people with irregular sleeping schedules and a new Sleep Regularity metric. These features will be available for both the Gen 2 and Gen 3 versions of the Oura Ring, but the body clock and chronotype feature will require an active subscription.
