The best smart rings for tracking sleep and health
In 2025, smart rings carve a niche as discreet health trackers. The Oura Ring 4 reigns supreme with a slimmer titanium design, better battery, and refined sensors—though you’ll need its $6/month subscription to unlock all features. If you balk at fees, Samsung’s Galaxy Ring, Ultrahuman Ring Air, and budget-friendly RingConn Gen 2 Air deliver solid hardware without monthly dues. Whether you’re a wellness-oriented sleeper or a casual athlete, there’s a smart ring for you.
