Oura Ring Gen 3

Oura's Ring tracks sleep, heart rate, and body temperature from your finger instead of your wrist, and the form factor is the main reason I want 1 over a Fitbit or Apple Watch. Weighing about 6 grams, the titanium body looks like a regular ring. Wearing health tracking hardware doesn't require the chunky wristband that announces you are optimizing yourself. Sleep tracking is reportedly more accurate than wrist-based devices because the blood vessels in your fingers are closer to the surface. Each morning a readiness score synthesizes your sleep, recovery, and heart rate variability into a single number. Adding daytime heart rate monitoring and blood oxygen sensing in Gen 3 pushes it closer to smartwatch territory without the screen, notifications, or general distraction that comes with wearing a computer on your arm. At $300 plus a $6 per month subscription for full analytics, the total cost of ownership is significant. But The tradeoff is a tracking device that disappears into your daily life rather than demanding your attention.
