## Summary description

Ultrahuman Ring AIR is a smart ring activity tracker for men and women designed to monitor sleep and fitness. It features a round titanium form factor, 24 mAh LiPo battery providing up to 6 days of use, and USB‑C to USB‑C cable for charging. Compatible with Android 8–13 and iOS 15–16. Tracks heart rate and activity metrics for daily health and training insights.

## Long description

The Ultrahuman Ring AIR is a compact smart ring for men and women that monitors sleep, recovery and daily activity. Built with a round titanium body and a lightweight design, it collects fingertip biomarker data to deliver detailed insights into sleep stages, heart rate variability (HRV), skin temperature and overall wellness. The ring connects via Bluetooth, charges with a USB‑C to USB‑C cable and offers up to six days of battery life on a 24 mAh Li‑Po cell.
Advantages
Fingertip sensing provides higher-precision readings than typical wrist-worn devices, improving accuracy for sleep and recovery metrics. At approximately 2.4 grams and with a hypoallergenic inner lining, the titanium ring is comfortable to wear day and night while remaining durable. The device combines continuous physiological monitoring with dynamic recovery scoring and everyday sleep insights to help you make informed decisions about rest and training.
Suitable for
People who want detailed sleep stage tracking and daily sleep scores
Users seeking recovery and HRV insights for training or stress management
Anyone preferring a low-profile, lightweight wearable instead of a wrist device
Android (8–13) and iOS (15–16) smartphone users who need Bluetooth connectivity
When it may not be suitable
This ring may not be appropriate for users requiring continuous on-screen interaction or smartwatch-style notifications, as it is focused on passive physiological monitoring rather than a full-featured smartwatch interface. It may also be unsuitable for people who cannot wear rings for medical or comfort reasons, or for those who need compatibility with older or unsupported mobile OS versions.

What to consider before purchase
Confirm the correct ring size for comfortable, consistent sensor contact
Ensure your smartphone runs a supported OS version (Android 8–13 or iOS 15–16)
Be aware that the device focuses on passive health monitoring rather than smartwatch features
Check for any skin sensitivities to metals despite the hypoallergenic lining
Usage recommendations
Wear the Ultrahuman Ring AIR continuously, including overnight, for the most accurate sleep and recovery insights. Keep the ring’s contact surface clean and maintain a snug but comfortable fit; charge regularly to avoid gaps in data collection.
