R6 Smart Ring — Sleep Tracker Heart Rate Blood Oxygen Step Counter Waterproof

All-day health tracking on your finger. The AJ King R6 Smart Ring monitors your health continuously — tracking heart rate, blood oxygen, blood pressure, heart rate variability, body temperature, steps, sleep stages, and emotional state — all from a lightweight ring worn on your finger. No screen to charge, no watch to wear, just a discreet ring that collects your health data around the clock.

The Bluetooth connection syncs data to your smartphone for detailed sleep analysis, sport tracking, and wellness insights. Waterproof construction means it goes wherever you do — including the shower and pool. Available in sizes 8 through 12 in Black, Silver, and Gold, each with a matching charging case.
