The Oura Ring 4 is the default recommendation in this category and the highest-rated ring here at 4.4. PCMag scored it 4 out of 5 and Android Police 8.5 out of 10, both pointing at the same strengths: sleep and recovery tracking, up to eight days of battery, and a fully titanium body with the old sensor bumps flattened out. It costs $349, then $5.99 a month, and without that subscription you get three daily scores and little else.
- — Improved 8-day battery life (up from 7 days)
- — Fully titanium build with wider range of sizes (4-15)
- — Requires a subscription for full features; basic data only available without membership
- — Not the best for detailed workout data tracking
