Key specifications: up to 6 days battery life, 24 mAh LiPo battery, USB-C to USB-C cable included. Compatible with Android 8.0–13.0 and iOS 15–16. Designed to track heart rate, sleep stages and daily activity for men and women.

## Long description

The Ultrahuman Ring AIR is a compact smart ring activity tracker designed for sleep and fitness monitoring in a matte grey round form (Size 6). Lightweight and intended for both men and women, it provides continuous tracking of sleep stages, heart rate and daily activity while offering up to six days of battery life on a 24 mAh LiPo cell. The device connects via Bluetooth and includes a USB-C to USB-C charging cable; it is compatible with Android 8.0–13.0 and iOS 15–16.
Advantages
The ring delivers fingertip biomarker readings for improved accuracy compared with wrist-worn devices, capturing detailed metrics such as heart rate variability (HRV) and skin temperature. At about 2.4 grams it is exceptionally light and uses a hypoallergenic inner lining for comfortable continuous wear. Built-in algorithms provide daily sleep scores and a Dynamic Recovery score that combine sleep, HRV, stress rhythm and temperature data to guide recovery and rest strategies.
Suitable for
People who want detailed sleep stage tracking and daily sleep scoring
Users seeking continuous heart rate and HRV monitoring
Anyone looking to monitor recovery and manage stress using physiological data
Active individuals who want a discreet, lightweight fitness tracker
When it may not be suitable
The Ultrahuman Ring AIR focuses on sleep, recovery and general activity insights rather than advanced sports metrics like GPS-based distance or pace tracking. If you require built-in GPS, swim-specific tracking with guaranteed water-sport ratings, or specialized training features, a different device may better meet those needs. Also, precise compatibility depends on running Android 8.0–13.0 or iOS 15–16.
Key specifications
Form factor: round smart ring, matte grey, Size 6
Battery: 24 mAh Lithium Polymer (LiPo), up to 6 days typical use

How to use
Wear the Ultrahuman Ring AIR on a finger that fits comfortably; the hypoallergenic lining is designed for continuous day-and-night use. Pair the ring with the companion app via Bluetooth on a compatible Android or iOS device to enable syncing and view detailed metrics such as sleep stages, HRV and Recovery Score. Charge the ring with the supplied USB-C to USB-C cable when the app notifies you of low battery; typical battery life is up to six days depending on usage.
What to consider before purchase
Ensure your smartphone runs a compatible OS (Android 8.0–13.0 or iOS 15–16)
Choose the correct ring size for continuous comfortable wear (this description is for Size 6)
Consider whether you need GPS or swim-specific features, which this ring does not provide
Usage recommendations
For best results, wear the ring overnight to obtain complete sleep-stage data and regularly sync with the app. Use the Recovery Score and daily sleep insights to plan rest, naps, and breathwork exercises for improved recovery.
