## Long description

Ultrahuman Ring AIR is a discreet smart ring activity tracker in a round form factor designed to monitor sleep, recovery and daily activity for men and women. Size 6 in a grey finish, the ring integrates fingertip biomarker sensing to provide continuous measurements of sleep stages, heart-rate metrics and skin temperature. A 24 mAh LiPo battery supports up to 6 days of use on a single charge. The package includes a USB-C to USB-C cable and the tracker provides core tracking functionality without an app subscription. Compatible with Android 8.0–13.0 and iOS 15–16, the device is intended for regular, all-day wear to gather accurate physiological data.
Advantages
The ring’s fingertip sensors capture physiological signals with higher perfusion and arteriole density compared with wrist wearables, enabling more precise readings of heart rate variability (HRV), skin temperature and sleep staging. Its featherlight construction and hypoallergenic inner lining allow comfortable continuous wear day and night at approximately 2.4 grams, reducing interference with daily activities and sleep. Battery life of up to six days lowers charging frequency, while USB-C charging enables fast, convenient recharging. Core tracking features are available without an ongoing app fee.
