Track your health and fitness with the Ultrahuman Air Smart Ring. Features include heart rate, sleep analysis, menstrual cycle tracking, body recovery insights, caffeine intake monitoring, temperature and HRV, and fitness metrics, all via Bluetooth and an app. Smaller and smarter than a watch. Size 8. Color: Raw Titanium. Used for 2 days. Original retail price: $350. Ring size gauges are available online. I regularly wear size 7, but needed a 9. Message with questions.
