The RingConn Gen 2 Air keeps the Gen 2's sensor set and drops the price. PCMag's Andrew Gebhart calls it a well-rounded smart ring that does not sacrifice looks, and Tom's Guide says it beats the Oura Ring 4 in three big ways, chiefly price and battery. Heart rate, HRV, SpO2, skin temperature, stress and sleep are all tracked with no subscription. Sleep apnoea detection is gone and the clamshell charging case is now a puck.
- — Affordable price point compared to premium smart rings like the Oura Ring 4
- — Accurate heart rate monitoring during workouts and rest
- — Waterproof design allows for swimming and showering
- — Sleep apnoea detection is reserved for the pricier Gen 2
- — USB-C charging puck replaces the Gen 2's self-powered clamshell case
- — Workout and training tools are thin next to a fitness watch
