THE RING OF YOUR DREAMS

Ultrahuman Ring AIR is the perfect sleep tracker ring. Along with insights on all your sleep stages — REM, Deep Sleep, Light Sleep and Wakefulness, get actionable steps to improve sleep so you're ready for the day.

DESIGNED TO KEEP YOU MOVING

The 'Movement Index' is designed to keep you moving all day for optimum glucose metabolism, and to increase your non-exercise energy usage through the day. With this all-in-one activity and fitness tracker, you can track steps, workouts and calories for insights into your all-day activity. All features work together seamlessly, to make sure you get the most out of the smart ring. Workout Tracking is now easy, with a dedicated Workout Mode that tracks Heart Rate during workouts — you can get insights into your cardiovascular response, track intensity levels, and make informed decisions to improve your fitness outcomes.

ENHANCED RECOVERY

Ring AIR is geared to help you recover better, with focused recovery tracking. The 'Dynamic Recovery Score' is derived from a blend of key metrics including heart rate monitoring, Heart Rate Variability (HRV) and skin temperature that track not only sleep but also every aspect of your lifestyle, giving you actionable insights. Designed to evolve with you, Dynamic Recovery will update in real-time when you take naps, sauna sessions or any contributors to enhance your recovery.

FUNCTIONALLY AESTHETIC

The Ultrahuman Ring AIR is forged with space grade titanium. Meticulously designed for enhanced comfort, this sleek device combines minimal form factor with precise performance, enabling users to effortlessly monitor key health indicators such as Sleep, Movement, Heart Rate (HR), Heart Rate Variability (HRV), and skin temperature.

WOMEN'S HEALTH

Ring Air incorporates cycle-based scores that uniquely characterise women’s physiology. With the Cycle Tracking PowerPlug, women get insights and personalised guidance for every phase of their cycle (Menstruation, Ovulation, Follicular, and Luteal Phases). With the Pregnancy Mode PowerPlug, expecting mothers get tailored insights throughout each trimester. With these, and more personalised features on the way, Ring AIR is undoubtedly a smart ring for women as well.

A UNIQUE APPROACH TO STRESS

A game changing perspective on stress, it considers the variations in your Heart Rate (HR), Heart Rate Variability (HRV), and Resting Heart Rate (RHR) against the backdrop of your circadian rhythm.

THE POWER OF UPTO 6 DAYS IN 2 HOURS

The Ultrahuman Ring AIR has a powerful battery that lasts up to 6 days, on a 2 hour charge.

CIRCADIAN PHASE ALIGNMENT

Circadian Rhythms are 24-hour cycles that regulate the body's sleep-wake cycle and other essential functions. The Circadian Alignment PowerPlug helps you align your circadian rhythms with nature, for optimum health.
