## Long description

The Ultrahuman Ring AIR is a compact smart ring activity tracker in matte grey, size 12, designed for continuous wear to monitor sleep, fitness and heart rate. Its lightweight 2.4 g and slim 2.4 mm profile make it comfortable for day‑to‑day use and overnight wear. The ring collects sleep data, skin temperature, heart rate and movement to provide a consolidated view of recovery, circadian phase and activity levels. Built for compatibility with Android 8+ and iOS 15+, the device includes a USB‑C charging cable and offers up to 6 days of battery life from its 24 mAh Li‑Po battery.
Advantages
The ring combines a nearly invisible form factor with continuous biometric monitoring, delivering sleep insights through a single Sleep Index and tracking skin temperature, heart rate variability (HRV) and movement. It provides personalised nudges and real‑time alerts to support daily choices, while the Phase Response Curve and Movement Index help understand circadian shifts and encourage regular activity for metabolic benefits. Lightweight construction and long battery runtime reduce interruptions to daily routines.
Suitable for
People who want continuous sleep analysis and overnight recovery tracking
Users seeking discreet, lightweight wearable for daily activity and heart rate monitoring
Those interested in skin temperature and circadian rhythm insights
People wanting personalised nudges to improve daily habits
When it may not be suitable
The Ultrahuman Ring AIR is compact and focused on biometric tracking rather than complex smartwatch features. It does not replace devices that require large displays, advanced third‑party apps, or on‑device interactions. Users who need extensive app integrations, GPS‑based sports tracking, or a full smartwatch interface may find it limited.
