RingConn Gen 2

The RingConn Gen 2 Air delivers smart ring sleep tracking at an entry-level price point without requiring ongoing subscriptions. Verified reviews consistently praise the ring's comfort during sleep, with its 2-gram weight and smooth titanium finish eliminating the wrist awareness issues common to watches. Sleep stage accuracy scores well in buyer feedback, with users noting consistent REM and deep sleep detection that aligns with subjective sleep quality. The ring captures heart rate variability, blood oxygen trends, and body temperature shifts throughout the night, feeding a surprisingly detailed morning readiness score. Battery life extends to six days per charge, removing the friction of nightly charging rituals. The Air variant trades sapphire crystal for a polymer coating to hit the lower price, a concession that shows up in durability scores with some users reporting finish wear after six months of daily use. The companion app lacks third-party integrations compared to Oura or Apple, but for buyers prioritizing raw sleep data without ecosystem lock-in, this omission matters less. Value scores rank highest here due to the absence of monthly fees and the sub-$200 entry cost. This pick works best for sleep-focused users who want unobtrusive tracking, don't need GPS or notifications, and prefer charging weekly rather than daily.
