The Ultrahuman Ring AIR is an advanced health and fitness tracking smart ring featuring comprehensive biometric monitoring in an ultra-lightweight design. Weighing only 2.4 to 3.6 grams depending on size, it is 11 times lighter than a typical smartwatch and measures just 2.45 to 2.8 millimeters thick. The Bionic Gold finish is crafted from fighter jet-grade titanium reinforced with tungsten carbide carbon coating, making it resistant to everyday wear and tear. The inner surface features medical-grade hypoallergenic epoxy resin for comfortable 24/7 wear.

The ring tracks sleep quality with detailed analysis of sleep stages, REM cycles, and provides a daily Sleep Score to help improve rest patterns. Dynamic Recovery monitoring analyzes heart rate variability, skin temperature, stress rhythm, and other physiological markers to provide a real-time Recovery Score throughout the day. Advanced health features include continuous heart rate monitoring, AFib detection for early identification of atrial fibrillation, cardio adaptability analysis, and women's health tracking with tailored menstrual and pregnancy insights. The ring also functions as a fitness tracker monitoring steps, calories, and automatically detecting activities like outdoor walks and naps.

Battery life lasts 4 to 6 days on a full charge, requiring 180 minutes to fully recharge from 0% to 100% using the included standard ring charger and USB Type-C cable. The ring connects via Bluetooth Low Energy 5.0 and is compatible with iPhones running iOS 15 or later and Android devices running Android 6 or later. No subscription fees are required for lifelong access to all health data and features. The ring includes an infrared photoplethysmography PPG sensor, non-contact medical-grade skin temperature sensor, 6-axis motion sensors, and red, green, and infrared LEDs for comprehensive heart rate and oxygen saturation monitoring.
