Ultrahuman Ring Air Size 12 Matte Grey

The Ring Air Size 12 Matte Grey tracks heart rate, sleep, steps, and skin temperature for daily health monitoring.

Sized for those who prefer a ring fit over a wristband, this Ultrahuman fitness tracker blends into your routine whether you are at work, sleeping, or exercising. Its lightweight construction and matte grey finish suit continuous wear, while the ring form factor is ideal for users who want discreet biometric tracking without a screen.

The fighter jet grade titanium shell is reinforced with a tungsten carbide carbon coating for durability, and the ring is water resistant up to 100 meters for up to 12 hours, making it suitable for swimming and showering. It connects to iPhones running iOS 15 or later and Android devices running Android 6 or later via Bluetooth v5.0. The battery lasts 4 to 6 days on a full charge, reducing the need for frequent charging.

Model 170139 in grey comes with a 1 year manufacturer's warranty.
