## Long description

Ultrahuman Ring AIR is a compact smart ring for continuous sleep and fitness monitoring. With a round silver form factor and size 9, it measures heart rate, sleep stages, skin temperature and activity to provide recovery and wellness insights. The ring is lightweight and hypoallergenic for comfortable all‑day wear and pairs with iOS 15+ and Android 8+ devices. A built‑in 24 mAh LiPo battery provides up to 6 days of runtime and the package includes a USB‑C to USB‑C charging cable.
Advantages
The Ultrahuman Ring AIR delivers fingertip biomarker measurements that offer higher arterial blood flow and denser signal than wrist devices, improving accuracy for heart rate variability, sleep staging and skin temperature. At approximately 2.4 grams and with a smooth hypoallergenic inner lining, the ring is unobtrusive for day and night use while maintaining a durable silver finish. Its integrated Dynamic Recovery analytics combine multiple physiological markers to produce an actionable recovery score.
Suitable for
People who want detailed sleep analysis and daily sleep scores
Users seeking continuous heart rate and HRV monitoring
Athletes or active users tracking recovery and activity
Anyone preferring a lightweight, low‑profile wearable
When it may not be suitable
The ring may not be suitable for users who require smartwatch features such as an always‑on display, built‑in GPS, or third‑party app integration that depends on a wristwatch form factor. It also may not be ideal for those who cannot wear rings due to finger size limitations, certain skin sensitivities despite hypoallergenic materials, or jobs that prevent wearing jewelry.
