Ultrahuman Ring Air Size 10 Space Silver

The Ring Air Size 10 Space Silver tracks sleep, heart rate, steps, and skin temperature for continuous wellness monitoring.

Designed for everyday wear, this Ultrahuman fitness tracker fits securely on your finger and weighs between 2.4 and 3.6g. Its fighter jet grade titanium shell is reinforced with a tungsten carbide carbon coating, while the hypoallergenic epoxy resin inner layer helps maintain comfort during overnight use. The fixed size 10 ring ensures accurate readings and is not adjustable, so choosing the correct fit is important.

Bluetooth v5.0 connectivity allows the ring to sync 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 is water resistant up to 100 meters for up to 12 hours. Sensor technology includes infrared photoplethysmography, non-contact medical-grade skin temperature, and a 6-axis motion sensor.
