Ultrahuman Ring Air Size 11 Raw Titanium

The Ring Air Size 11 Raw Titanium tracks heart rate, sleep, steps, and skin temperature for all-day health monitoring.

Sized for a snug fit on one finger, this Ultrahuman fitness tracker suits users who want continuous insights without the bulk of a smartwatch. The lightweight ring is crafted from fighter jet grade titanium with a hypoallergenic epoxy resin inner coating, making it comfortable for everyday wear.

Bluetooth v5.0 connectivity links the ring to 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 for accurate tracking.
