I tried a subscription-less smart ring in place of my Oura - and it did some things better
Briefly

The article discusses the shortcomings of the Oura Ring 4 regarding its battery life, which claims to last eight days but typically only lasts four. In contrast, the RingConn 2 boasts a remarkable 10 to 12-day battery life and is priced at $300 with no subscription fees for health data access. It features a unique square design, remains comfortable to wear, and includes a charging case that can prolong battery life to over 150 days. Additionally, smart rings generally track important health metrics like sleep and activity readiness.
