The RingConn Gen 2 is one of the thinnest and lightest smart rings available today. Subscription-free and compatible with iPhone and Android smartphones, it boasts an impressive range of sleep-tracking features, including sleep apnea detection, personalized AI-backed wellness tips, up to 12 days of battery life (or 150-plus days with an optional quick-charge case) and a lower starting price than the Oura Ring 4, the best smart ring we've tested.
The RingConn Gen 2 is one of the three recently launched subscription-free smart rings vying for the title of best Oura Ring alternative in 2025. The other two are the Circular Ring 2 and Luna Ring 2, both of which I checked out in person at CES 2025.
