- Oura Ring 4Gen 4$349Oura~7-day battery

9.0/ 10 - Ultrahuman Ring AirGen 1$349Ultrahuman~6-day battery
Oura-class sleep data with no membership; the app is busier and metabolic features are still maturing.

Comfortable, no subscription, and tightly tied into Samsung Health — best alongside a Galaxy phone.
8.4/ 10 - RingConn Gen 2Gen 2$299RingConn~7-day battery
A week of battery, no fees and solid sleep tracking; HRV trends lag the Oura on restless nights.

The same Oura internals in a fully round, scratch-resistant shell — for a higher price.
