## Summary description

Ultrahuman Ring AIR is a smart ring activity tracker for men and women that monitors sleep and fitness. It features a round silver form factor, 24 mAh LiPo battery with up to 6 days runtime, and USB‑C charging (USB‑C to USB‑C cable included). Compatible with Android 8+ and iOS 15+ for heart‑rate, sleep stages and activity tracking without mandatory app fees.

## Long description

Ultrahuman Ring AIR is a compact smart ring designed for both men and women to monitor sleep, recovery and daily activity. The silver, round form factor houses fingertip-level sensors that provide detailed sleep stage analysis, heart rate variability (HRV), skin temperature and activity monitoring. With a lightweight, hypoallergenic design and up to 6 days of battery life, the ring is intended for continuous wear day and night to deliver ongoing wellness insights.
Advantages
The Ultrahuman Ring AIR offers fingertip biomarker accuracy that can outperform wrist-based wearables for sleep and recovery metrics, thanks to higher blood flow and arteriole density in the fingers. At approximately 2.4 grams and with a smooth hypoallergenic inner surface, the ring is comfortable for round‑the‑clock wear. It combines sleep staging, dynamic recovery scoring and basic activity tracking in a single, unobtrusive device with USB‑C charging and cross‑platform compatibility.
Suitable for
People who want detailed sleep stage tracking and an everyday sleep score
Users focused on recovery and HRV-based readiness or recovery insights
Anyone seeking a lightweight, low-profile alternative to wrist wearables
Android (8+) and iOS (15+) users who want basic activity and heart rate monitoring without mandatory app fees
When it may not be suitable
The Ultrahuman Ring AIR is not intended for use as a medical diagnostic device and should not replace professional medical monitoring or advice. Users who need advanced activity metrics such as GPS-based distance tracking, detailed exercise modes, or medical-grade sensors may find the ring’s feature set limited for those specific use cases.
