## Long description

The Ultrahuman Ring AIR is a lightweight, unisex smart ring designed to monitor sleep, recovery and daily activity.

Suitable for
People who want detailed sleep staging and sleep quality scores

Anyone wanting continuous, low-profile tracking of heart rate and daily activity
Those who prefer a lightweight, discreet wearable for 24/7 use
When it may not be suitable
This smart ring may not be suitable for users who require medical-grade monitoring or certified clinical devices; it is intended for wellness and fitness insights rather than diagnostic purposes.
