## Long description

The Ultrahuman Ring AIR (Size 14, Silver) is a compact smart ring designed for continuous sleep and fitness monitoring. It combines infrared PPG SpO2 sensing, heart-rate and heart-rate variability tracking, activity and recovery insights, and multi-biomarker women’s health features in a space-grade titanium band with water resistance up to 100 m. The ring supports up to six days of battery life from a 24 mAh LiPo cell and connects via Bluetooth 5.0 to the Ultrahuman app. Ultrahuman offers standard features in the app without a subscription.
Advantages
Ultrahuman Ring AIR delivers detailed sleep-stage analysis, comprehensive activity and recovery metrics, and women’s health tracking including cycle, fertile-window prediction and pregnancy mode. The device is made from lightweight, durable space-grade titanium and offers a minimal form factor suitable for 24/7 wear. Advanced metrics such as Stress Rhythm Score and configurable PowerPlugs provide deeper context for heart response, screen-time effects and caffeine timing. A dedicated sizing kit is recommended to ensure an accurate fit before purchase.
Suitable for
Users who want continuous sleep staging and recovery tracking
People tracking daily activity, steps, workouts and calories
Those seeking multi-biomarker women’s health insights (cycle, ovulation, pregnancy)
Swimmers and active users who need water-resistant wearable (up to 100 m)
When it may not be suitable
The Ultrahuman Ring AIR uses ring-specific sizing that differs from standard ring sizes; buyers should purchase the Ultrahuman Sizing Kit first to determine the correct size and avoid exchanges. While the app’s standard features are free, specialized insights available via PowerPlugs may require configuration within the app. The ring is best suited to users comfortable wearing a metal ring continuously; those who prefer non-metal wearables or very thin form factors may find alternatives more suitable.

How to use
Measure your ring size using the Ultrahuman Sizing Kit before ordering and select the corresponding size.

Wear the ring continuously for best results: it records sleep, activity and physiological signals automatically. Use the app to view sleep-stage breakdown, recovery recommendations, Stress Rhythm Score and women’s health insights. Update firmware through the app when prompted.
What to consider before purchase
Purchase the Ultrahuman Sizing Kit first to determine accurate ring size
Confirm device compatibility with your phone (Android 6–13)
Decide whether you need the model with SpO2 sensing and confirm size 14 matches your measurement
Understand that some advanced app features (PowerPlugs) require in-app configuration
Usage recommendations
Wear the ring continuously, especially during sleep, and keep it regularly charged to maintain up to six days of runtime; use the Ultrahuman app to review sleep stages, recovery insights and women’s health tracking for more accurate longitudinal data.
