The review
Why we put this on the shelf.
Oura is the gold standard for at-home sleep and recovery tracking. Gen 4 is smaller, lighter, and uses an updated heart-rate sensor with better accuracy during workouts. Sleep staging is independently validated against polysomnography. Cycle tracking, daytime stress, and HRV detection are best-in-class. Battery lasts a full week.
