Ultrahuman Ring Air Size 11 Brushed Rose Gold

The Ring Air Size 11 Brushed Rose Gold tracks heart rate, sleep, steps, and skin temperature for continuous health monitoring.

This Ultrahuman fitness tracker is designed for users who want discreet, all-day and night tracking without the bulk of a smartwatch. Its fixed size 11 ring fits securely for reliable sensor readings, making it suitable for those who prefer a snug fit and want to monitor their wellness trends over time.

Constructed from fighter jet grade titanium with a brushed rose gold finish, the ring is water resistant up to 100 meters for up to 12 hours. It connects via Bluetooth v5.0 and is compatible with iPhones running iOS 15 or later and Android devices running Android 6 or later. The battery lasts 4 to 6 days on a full charge, and the ring uses infrared photoplethysmography and a 6-axis motion sensor to track circadian rhythm, temperature-based ovulation prediction, caffeine window detection, AFib detection, and sleep.

Model 170796 in Brown comes with a 1 year manufacturer's warranty.
