## Summary description

Ultrahuman Ring AIR is a smart ring activity tracker designed for sleep and fitness monitoring. It features infrared photoplethysmography (PPG) for blood oxygen and heart‑rate sensing, a round gold form factor, and a 24 mAh LiPo battery providing up to 6 days of use. Compact dimensions (8.1 mm width, 2.45 mm thickness) and Android compatibility make it suitable for continuous wear and daily activity, sleep analysis, and recovery tracking without a standard app fee.

## Long description

The Ultrahuman Ring AIR is a compact smart ring for sleep and fitness tracking in a round gold form. Designed for continuous day-and-night wear, it uses infrared photoplethysmography (PPG) at the fingertip to measure heart rate and blood oxygen (SpO2), and collects data to assess sleep stages, recovery, and daily activity. The ring is lightweight with a slim profile and offers up to six days of battery life on a 24 mAh LiPo cell, with Bluetooth 5.0 connectivity for pairing with Android devices.
Advantages
The ring delivers fingertip biomarker accuracy that can be higher than wrist-based wearables for metrics such as heart rate variability (HRV), skin temperature and SpO2. Weighing approximately 2.4 grams and featuring a hypoallergenic smooth inner lining, it is engineered for comfortable continuous wear without bulk. Built-in recovery analytics provide a consolidated Recovery Score by combining sleep, stress rhythm, skin temperature and HRV to guide rest and recovery decisions.
Suitable for
People who want detailed sleep stage and recovery insights
Users seeking a minimal, lightweight wearable for 24/7 monitoring
Those who prefer fingertip biometrics for more precise heart rate and SpO2 readings
Fitness-conscious users tracking activity, calories, steps and active minutes
When it may not be suitable
The Ultrahuman Ring AIR is not a medical device and should not be used for clinical diagnosis or to replace professional medical equipment. Users who require certified medical-grade monitoring or continuous on-demand measurements for clinical conditions may need alternative devices. Additionally, those who prefer a full smartwatch interface with a display and apps on the wrist may find the ring’s silent, non-display design limiting.

How to use

What to consider before purchase
