Oura Ring Generation 3

The Oura Ring Gen 3 is the health tracker for people who hate wearing fitness bands. It looks like a regular ring but packs infrared sensors that track sleep stages, heart rate, HRV, blood oxygen, skin temperature, and activity — 24/7. Sleep tracking is where Oura truly excels. It breaks down your night into REM, deep, and light sleep with accuracy that rivals clinical sleep studies. The Readiness Score each morning tells you whether to push hard or take it easy. Battery lasts 4-7 days. Titanium body, water-resistant to 100m. The app is clean and actionable — not overwhelming. Requires a subscription ($5.99/month) for full insights, which is the main downside. But for sleep optimization and holistic health tracking, nothing beats it.
