Oura Ring Gen 4
The verdict
Free sizing kit ($10 credited back), 7-day battery, titanium build, and the new Smart Sensing platform. The data is genuinely good for spotting sleep and recovery patterns.
Oura Ring Gen 4 — about $349 · 4.0★ from ~7,000+ reviews · honest blind-shopper read: there's no screen at all — every stat lives in the app, which is screen-reader-friendly text. Sleep, readiness, and activity tracking from a ring you never look at.
The honest math: $349 plus a $5.99/month membership to see most of your data — and the Ring 5 now exists, so the Gen 4 is last year's model. Buy it for the passive tracking, not the subscription economics.
