Oura Ring 4

Oura Ring 4 is my #1 because it’s the most accurate and the best all-around smart ring for sleep and fitness. It automatically detects activities, tracks key health signals like heart rate, temperature, blood oxygen, and movement, and its readiness insights are the closest to how you actually feel.

  • +Automatic activity detection across many activities (even housework)
  • +Tracks heart rate, body temperature, blood oxygen, and movement with strong algorithms
  • +Readiness-based goal adjustments and strong recovery insights
  • +Slimmer, lighter design with improved sensors and smoother interior

Cons

  • -Subscription required for advanced insights (detailed sleep, temperature trends, restorative time)
  • -More expensive overall due to subscription
