## Long description

The Ultrahuman Ring AIR is a compact smart ring in a round silver form factor designed for sleep and fitness monitoring. Sized 13, it provides continuous heart rate and activity tracking with fingertip biomarker accuracy, skin temperature measurement and daily recovery insights. The ring pairs with Android and iOS devices and offers up to 6 days of battery life on a 24 mAh LiPo cell. Its lightweight, hypoallergenic design is intended for comfortable all-day and night wear while delivering detailed sleep, recovery and movement data for a clearer picture of personal wellness.
Advantages
Fingertip-based sensing gives more accurate readings of heart rate variability, skin temperature and sleep stages compared with many wrist-based devices. At about 2.4 grams and with a smooth hypoallergenic inner lining, the ring is designed to be barely noticeable while worn and comfortable for continuous use. The device combines continuous monitoring of sleep, HRV, temperature and movement with a Recovery Score and personalized nudges to help optimise rest and daily recovery practices. A compact USB-C cable is included and the basic feature set works without recurring app fees.
Suitable for
People who want detailed sleep stage analysis and a daily sleep score
Users seeking continuous HRV and skin temperature monitoring for recovery insights
Those wanting a lightweight, discreet wearable for 24/7 tracking
Fitness-minded users who track movement and activity to support metabolic health
When it may not be suitable
The Ultrahuman Ring AIR is not a medical device and should not be used as a substitute for professional medical diagnostics or treatment. Users who need clinical-grade measurements or specific medical monitoring should consult healthcare professionals and consider specialist equipment. Very large or very small finger sizes outside the available sizing range may prevent an optimal fit.

What to consider before purchase
Ensure Size 13 matches your finger measurement for a secure, accurate fit
