## Long description

Ultrahuman Ring AIR is a low-profile smart ring designed for continuous sleep and fitness monitoring in a lightweight, discreet form. In a round silver finish and size 7, the ring provides continuous heart rate and activity tracking, sleep analysis using a Sleep Index, skin temperature monitoring, movement and HRV insights, and personalised nudges. The ring uses a 24 mAh LiPo battery for up to 6 days of typical use and includes a USB-C to USB-C charging cable. Compatible with Android 8+ and iOS 15+.
Advantages
The ring combines a very light and slim form factor with continuous biometric sensing, offering sleep, activity, temperature and heart-rate data without a bulky device. Its Sleep Index aggregates total sleep duration, resting heart rate and restfulness into a single metric. Temperature tracking and HRV insights support recovery and health monitoring while personalised real-time nudges help with behaviour adjustments.
Suitable for
 People who want unobtrusive, 24/7 sleep and activity monitoring
 Users seeking continuous heart-rate and HRV metrics for recovery tracking
 Anyone wanting simple sleep scoring and skin temperature trends
 Individuals preferring a compact wearable with multi-day battery life
When it may not be suitable
The ring’s very slim and discreet design prioritises comfort and basic biometric tracking; it is not a full-featured smartwatch replacement and lacks a display for on-device interaction. If you require built-in GPS, a large screen, or advanced smartwatch apps, this ring may not meet those needs.
Key specifications

Charge the ring using the supplied USB-C cable when battery levels are low; typical charge cycles provide up to six days of use.
What to consider before purchase
 Check that size 7 fits comfortably — ring sizing affects sensor accuracy and comfort
 Verify your phone meets compatibility requirements (Android 8+ or iOS 15+)
 Consider whether you need smartwatch features like a display, on-device apps, or GPS
 Battery life expectations: up to 6 days depending on usage and sensor sampling
Usage recommendations
For best results, wear the ring continuously, ensure a snug but comfortable fit, sync regularly with the app, and charge before the battery is depleted. Use sleep and movement indices alongside HRV and temperature trends to monitor recovery and daily readiness.
