Product information

Description

The Ultrahuman Ring AIR is a compact smart ring for sleep and fitness tracking designed for daily wear. Built from space-grade titanium with a smooth hypoallergenic inner shell, the Ring AIR measures sleep stages, activity, heart metrics, skin temperature and blood oxygen (PPG SpO2). It supports USB-C wireless charging, offers up to six days of battery life, and is water-resistant to 100 m. Available in multiple sizes; this listing is for Size 5 in black.

Advantages

The ring provides continuous monitoring of sleep (REM, deep, light, wake), heart rate, heart rate variability (HRV), resting heart rate, skin temperature and SpO2 without requiring a subscription for standard features. Its lightweight, durable titanium construction and 100 m water resistance make it suitable for everyday use, workouts and swimming. Advanced women’s health tracking, fertility window prediction and pregnancy mode are included, alongside recovery metrics that combine key biomarkers for personalized insights.

Suitable for

  • Users who want continuous sleep and recovery tracking
  • Athletes and fitness enthusiasts monitoring activity, workouts and calories
  • People interested in heart health metrics (HR, HRV, RHR) and SpO2
  • Women tracking cycles, ovulation and pregnancy-related metrics
  • Anyone seeking a low-profile wearable with long battery life

When it may not be suitable

The Ultrahuman Ring AIR uses non-invasive PPG sensors and algorithms; it is not a medical device and should not replace professional medical diagnosis. Users requiring medical-grade oximetry or clinical heart monitoring should rely on certified medical equipment. Sizing differs from standard ring sizes, so purchasing the Ultrahuman Sizing Kit first is recommended to ensure an accurate fit.

Key specifications

  • Form factor: round smart ring, black, Size 5
  • Materials: space-grade titanium exterior, hypoallergenic inner shell
  • Sensors and metrics: PPG SpO2, continuous heart rate, HRV, skin temperature, activity and sleep stage tracking
  • Battery: 24 mAh LiPo, up to 6 days typical battery life
  • Charging: USB-C wireless charging compatible
  • Water resistance: up to 100 m
  • Connectivity: Bluetooth 5.0

How to use

Determine your correct ring size using the Ultrahuman Sizing Kit before purchase to avoid exchanges. Charge the ring using the included USB-C wireless charger and pair it with the Ultrahuman App via Bluetooth 5.0. Wear the ring on a finger where it fits comfortably and snugly; the device records biometrics continuously and syncs data to the app for sleep, activity, stress and recovery insights. Use the app to review trends, enable women’s health features or activate specific PowerPlugs for focused insights like cardio adaptability or screen time effects.

What to consider before purchase

  • Buy the Ultrahuman Sizing Kit first — sizes differ from standard ring sizing
  • Standard monitoring features work without a subscription; advanced or premium services may require app options
  • Not a medical device — consult a healthcare professional for clinical concerns

Usage recommendations

Wear the ring consistently, including during sleep and workouts, and charge it regularly to maintain continuous tracking. Use the Ultrahuman App to review sleep stages, recovery scores and women’s health metrics and enable relevant PowerPlugs for tailored insights.
