Ultrahuman Ring Air Size 13 Space Silver

The Ring Air Size 13 Air Silver tracks heart rate, sleep, steps, and skin temperature for everyday health monitoring.

Sized for a comfortable fit on larger fingers, this Ultrahuman fitness tracker suits users who want discreet, all-day wear without the bulk of a smartwatch. Its lightweight titanium build and hypoallergenic epoxy resin inner coating make it suitable for continuous use, including overnight and during exercise.

Bluetooth v5.0 connectivity pairs the ring with iPhones running iOS 15 or later and Android devices running Android 6 or later, so you can sync data and view insights in the Ultrahuman app. The battery lasts 4 to 6 days on a full charge, and the ring is water resistant up to 100 metres for up to 12 hours, making it practical for swimming and daily routines.

Model 170130 in silver comes with a 1 year manufacturer's warranty.
