Oura’s pitch is simple: the best wearables for sleep and recovery do not have screens. The Ring 4 reads HRV, body temp, and movement, then surfaces three scores — sleep, readiness, activity — in the morning. Because it has no display, it disappears on the hand and the 8-day battery means you barely notice charging it. The mandatory $5.99/month subscription is the catch.
