Ultrahuman Ring Air Size 06 Brushed Rose Gold

The Ring Air Size 06 Brushed Rose Gold tracks heart rate, sleep, steps, and skin temperature for everyday health monitoring.

Sized for a standard US ring size 6, this smart ring fits snugly and securely, making it suitable for continuous wear, including overnight. Its brushed rose gold finish is cosmetic, with the same tracking hardware as other Ultrahuman Ring Air models. The ring is compatible with iPhones running iOS 15 or later and Android devices running Android 6 or later, connecting via Bluetooth v5.0.

Constructed from fighter jet grade titanium reinforced with tungsten carbide carbon coating, the ring is water resistant up to 100 meters for up to 12 hours. Battery life lasts 4 to 6 days on a full charge, and the ring uses infrared photoplethysmography and non-contact medical-grade skin temperature sensors. It tracks circadian rhythm, temperature-based ovulation prediction, caffeine window detection, AFib detection, and sleep.

Model 170791 in brown comes with a 1 year manufacturer's warranty.
