#243 of 363Oura Ring Sleep Tracker

The Oura Ring tracks sleep, heart rate, body temperature, and activity from a titanium ring that looks like jewelry rather than a fitness device. Its form factor is the primary reason it succeeds where wrist-based trackers feel intrusive. Weighing about 6 grams, you forget you're wearing it within a day. The data it collects reflects your actual behavior rather than the behavior of someone who remembers they are being tracked. Each morning, the readiness score synthesizes a night of biometric data into a single number. It tells you whether to push hard or take it easy.
