Ultrahuman Ring Air Size 14 Space Silver

The Ring Air Size 14 Air Silver tracks sleep, heart rate, steps, and skin temperature for daily health monitoring.

This Ultrahuman fitness tracker suits users who want discreet, all-day tracking without the bulk of a smartwatch. Its lightweight titanium build and compact ring design make it comfortable for continuous wear, including overnight sleep tracking.

The device connects to iPhones running iOS 15 or later and Android devices running Android 6 or later via Bluetooth v5.0. It lasts 4 to 6 days on a full charge, so you can track your activity and recovery with fewer interruptions. Water resistance up to 100 metres for up to 12 hours means you can wear it during swimming or showering.
