## Summary description

Ultrahuman Ring AIR is a smart ring activity tracker designed for sleep and fitness monitoring. It features a round titanium form factor in Size 12, a 24 mAh LiPo battery providing up to 6 days of runtime, and USB-C charging. Compatible with Android 8+ and iOS 15+, it tracks heart rate and activity metrics and pairs with the mobile app (standard features have no app fee).

## Long description

The Ultrahuman Ring AIR is a lightweight smart ring designed for sleep and fitness monitoring. Finished in raw titanium and sized as Size 12, the ring measures key physiological signals from the finger to provide detailed sleep staging, continuous heart-rate tracking, and recovery insights. With a 24 mAh LiPo battery offering up to six days of typical use and USB-C charging, it pairs with the Ultrahuman mobile app on Android 8+ and iOS 15+ for data visualisation and personalised recommendations.
Advantages
The ring’s fingertip form factor improves measurement accuracy compared with wrist-worn devices by using higher blood flow and arteriole density at the finger. At approximately 2.4 grams and made from titanium with a hypoallergenic inner surface, it provides a near‑weightless fit suitable for continuous day-and-night wear. Combined sleep staging, HRV, skin temperature and activity monitoring deliver a unified recovery score and ongoing wellness insights without requiring a subscription for standard features.
Suitable for
People who want detailed sleep tracking and daily sleep scores
Users seeking recovery and HRV insights to guide training or stress management
Those who prefer a discreet, lightweight wearable instead of a wrist device
Smartphone users on Android 8+ or iOS 15+ who want app-based analysis
When it may not be suitable
This ring may not be suitable for users who require continuous on-wrist features such as visible notifications, large-screen interactions, or smartwatch apps. People who frequently change ring sizes or have occupations that risk ring damage may prefer a different wearable form factor.
Key specifications
Materials: Raw titanium exterior with hypoallergenic inner lining
Weight: approximately 2.4 grams

How to use
Fit the ring on a finger that provides a comfortable snug contact with the skin (commonly the index or middle finger). Install the Ultrahuman mobile app on a compatible smartphone, follow the in-app pairing instructions via Bluetooth, and allow the app necessary permissions for background data collection. Wear the ring continuously to capture overnight sleep data and daytime activity and recovery metrics; charge via the USB-C cable when the app indicates low battery to maintain uninterrupted tracking.
What to consider before purchase
Ensure Size 12 fits your intended finger — proper sizing affects measurement accuracy
Check smartphone compatibility: Android 8+ or iOS 15+
Decide if you need visible smartwatch features (notifications, apps) which this ring does not provide
Consider workplace or lifestyle conditions that could risk scratching or deforming a titanium ring
Usage recommendations
Wear the ring continuously, including during sleep, for the most accurate sleep staging and recovery scores. Keep the firmware and mobile app updated and recharge before the battery level becomes critical to avoid gaps in data collection.
