Oura Ring 5 Smart Ring vs RingConn Gen 3 Smart Ring

The RingConn Gen 3 is the better pick for most shoppers: it runs 10 to 14 days per charge, needs no subscription, and adds vibration alerts and sleep apnea tracking. The Oura Ring 5 is smaller, lighter and more polished, and its app and health insights are the most refined in the category. Reviewers praise Oura's comfort and data depth but note its subscription and narrower app sharing; RingConn owners value the battery life and no-fee model.

• Choose the Oura Ring 5 if you want the most polished app, the smallest ring, and you don't mind a subscription for full insights.
• Choose the RingConn Gen 3 if you want two-week battery life, vibration alerts, sleep apnea tracking and no subscription.
