## Long description

The Ultrahuman Ring AIR is a compact smart ring for sleep and fitness tracking designed for daily wear. Built from space-grade titanium with a smooth hypoallergenic inner shell, the Ring AIR measures sleep stages, activity, heart metrics, skin temperature and blood oxygen (PPG SpO2). It supports USB-C wireless charging, offers up to six days of battery life, and is water-resistant to 100 m. Available in multiple sizes; this listing is for Size 5 in black.
Advantages
The ring provides continuous monitoring of sleep (REM, deep, light, wake), heart rate, heart rate variability (HRV), resting heart rate, skin temperature and SpO2 without requiring a subscription for standard features. Its lightweight, durable titanium construction and 100 m water resistance make it suitable for everyday use, workouts and swimming. Advanced women’s health tracking, fertility window prediction and pregnancy mode are included, alongside recovery metrics that combine key biomarkers for personalized insights.
Suitable for
Users who want continuous sleep and recovery tracking
Athletes and fitness enthusiasts monitoring activity, workouts and calories
People interested in heart health metrics (HR, HRV, RHR) and SpO2
Women tracking cycles, ovulation and pregnancy-related metrics
Anyone seeking a low-profile wearable with long battery life
When it may not be suitable
The Ultrahuman Ring AIR uses non-invasive PPG sensors and algorithms; it is not a medical device and should not replace professional medical diagnosis. Users requiring medical-grade oximetry or clinical heart monitoring should rely on certified medical equipment. Sizing differs from standard ring sizes, so purchasing the Ultrahuman Sizing Kit first is recommended to ensure an accurate fit.
