The RingConn Gen 2 Air is a thin, light smart ring that tracks sleep, heart rate, blood oxygen, stress, activity and menstrual cycles without a subscription. It is 2 mm thick and weighs 2.5 to 4 g, so it sits closer to a plain band than most smart rings. Battery life runs up to 10 days, and it is waterproof to 328 ft. It suits people who want overnight health tracking without a screen or monthly fee. Against the Oura Ring it gives up some sleep and readiness depth, but it charges no subscription and costs less, and owners rate it highly for comfort and battery life.
