Ultrahuman Ring Air Size 13 Raw Titanium

The Ultrahuman Ring Air is a lightweight smart ring designed for comprehensive health and fitness monitoring. Weighing just 2.4 grams and made from aircraft-grade titanium with a tungsten carbide carbon coating, this unisex device offers exceptional durability and comfort. Available in size 13 with a raw titanium finish, the ring features advanced sensors, including infrared photoplethysmography for heart rate measurement, medical-grade non-contact skin temperature measurement, and 6-axis motion tracking. These sensors continuously monitor vital parameters such as heart rate variability, blood oxygen saturation, sleep phases, and physical activity. The rechargeable 24 mAh LiPo battery allows for up to 6 days of operation on a single charge, with a full recharge taking about 180 minutes via the included wireless charging station and USB-C cable. With a water resistance of up to 100 meters, the ring is suitable for swimming and various water activities. The companion app, available in 15 languages, provides detailed insights through specialized metrics, including a sleep index for analyzing sleep phases, a movement index for tracking daily activity, a recovery score for monitoring physiological recovery, and a dedicated workout mode for sports tracking. Additional features include recommendations for stimulant windows to optimize caffeine consumption and circadian phase alignment guidance to improve sleep-wake cycles. It is important to note that Ultrahuman Ring sizes differ from standard ring measurements, so using the sizing kit for the correct fit is necessary. The device operates without subscription fees for standard features and is compatible with health savings accounts and flexible spending account programs.
