Ultrahuman Ring AIR
#3 in Smart Ring · Rated 4.2
Featherweight sleep and recovery ring with AI health insights
Ultrahuman Ring AIR is a lightweight titanium smart ring designed for sleep tracking, recovery analytics, and daily activity metrics. It tracks sleep stages, heart rate variability, heart rate, movement, and skin temperature, with a strong emphasis on metabolic and recovery insights. The device is sold with sizing kits and an app-based experience that emphasizes subscription-free health data in many regions, while offering optional PowerPlug services (Cycle/Ovulation, nutrition, etc.). In the U.S., regulatory actions have affected availability for new US imports in 2025, but international sales continue. The Ring’s competitors often emphasize long battery life and a no-subscription data model; Ultrahuman has actively expanded its manufacturing footprint and services to broad markets.
