## Long description

Ultrahuman Ring AIR in Silver is a lightweight smart ring activity tracker designed for continuous daily wear. The ring combines a slim round form factor with a 24 mAh lithium‑polymer battery that delivers up to 6 days of use on a single charge. It ships with a USB‑C to USB‑C cable and pairs with mobile devices running Android 8.0+ and iOS 15+, enabling monitoring of activity, sleep, heart rate variability, skin temperature and other wearable metrics through the companion app.
Advantages
The ring’s 2.4‑gram weight and 2.4 mm profile provide an unobtrusive fit for day‑to‑day wear, reducing interference with daily tasks while allowing continuous sensing. Sleep monitoring is consolidated into a Sleep Index that evaluates total sleep duration, resting heart rate and restfulness to present a concise measure of sleep health. Continuous skin temperature tracking helps identify physiological changes related to exercise, stress or illness, while HRV insights support recovery assessment and readiness. The Movement Index encourages consistent activity to support glucose metabolism and non‑exercise energy expenditure. Personalized nudges and real‑time alerts help users act on data without needing deep technical knowledge.
Suitable for
Everyday activity and step tracking for users seeking a discreet wearable
Sleep monitoring and sleep quality assessment
Temperature and physiological trend tracking for wellness monitoring
Users who want HRV‑based recovery insights
People who prefer a compact, lightweight alternative to smartwatches
