Oura Ring 4 vs RingConn Gen 3 Smart Ring

Buy the RingConn Gen 3 if you want full health data without a subscription and a two-week battery. Buy the Oura Ring 4 if you want the most polished app, the deepest sleep and readiness insight, and a wider size range. Oura's titanium build and app ecosystem are more refined, and its 4.5 rating comes from a far larger pool of owners. RingConn matches it on sensors and beats it on battery and ongoing value, but its smaller review base and iOS-leaning listing make it the less proven pick.

• Choose the Oura Ring 4 if you want the most mature sleep and recovery tracking, a strong app, and you accept a subscription for full features.
• Choose the RingConn Gen 3 if you want no subscription, a 14-day battery, and on-finger vibration alerts.
