## Long description

Ultrahuman Ring AIR is a slim smart ring designed for sleep and fitness monitoring for both men and women. The ring combines fingertip photoplethysmography (PPG) technology with a lightweight, hypoallergenic design to provide continuous tracking of sleep stages, heart-related metrics and blood oxygen (SpO2). With USB-C charging and up to six days of battery life, the ring is a compact all-day wearable that focuses on precise physiological insights for recovery and wellness.
Advantages
The Ultrahuman Ring AIR offers fingertip-level accuracy by using infrared PPG sensors that benefit from higher blood flow and arteriole density in the finger, delivering more precise readings than many wrist-based devices. At 2.4 grams and 8.1 mm width it is exceptionally light and low-profile, with a smooth hypoallergenic inner lining for comfortable continuous wear. The device supports USB-C charging, provides up to six days of battery life, and includes metrics such as heart rate variability (HRV), SpO2, skin temperature trends, sleep stage analysis and a Recovery Score to help optimise rest and daily recovery.
Suitable for
People who want detailed sleep-stage tracking and daily sleep scores
Users seeking accurate heart-rate, HRV and SpO2 monitoring from a finger-worn device
Active individuals who want lightweight, unobtrusive all-day wear for recovery insights
Anyone looking for a compact wellness tracker with multi-day battery life and USB-C charging
When it may not be suitable
The ring may not be suitable for users who prefer wrist-based smartwatches with large displays or those who need continuous on-screen notifications and apps. It is also not intended as a medical diagnostic device; readings are intended for wellness and fitness insights rather than clinical diagnosis.

Weight: approx. 2.4 grams

How to use
Wear the Ultrahuman Ring AIR on a finger that provides a comfortable, snug fit—typically the index or middle finger—to ensure consistent sensor contact. Charge the ring via the included USB‑C cable and pair it with the companion app to view sleep reports, Recovery Score and physiological trends. Use the sleep and recovery insights from the app to adjust rest, naps and breathwork routines as needed. Standard features do not require a paid app subscription.
What to consider before purchase
Choose the correct ring size (Size 10 in this listing) for consistent sensor contact and comfort
Consider whether you prefer a finger-worn tracker over a wrist-worn smartwatch with a display
Understand that the device provides wellness insights and is not a substitute for medical equipment
Usage recommendations
For accurate readings, wear the ring continuously, especially during sleep and recovery periods. Keep the sensor area clean and ensure a snug fit for stable contact. Use the Recovery Score and sleep-stage data to plan rest, short naps and breathing exercises to support daily recovery.
