Designed for anyone wanting deeper health insights without another screen. This silver Oura Ring 4 in size 10 tracks over 50 metrics, including sleep, activity, stress, and heart health. You wear it 24/7, barely noticing its presence. Smart Sensing technology adapts to your unique finger, delivering accurate data all day and night.

The ring works hardest while you sleep. It captures your sleep stages, heart rate variability, and nightly skin temperature. Morning reports reveal how your night affects your day. That afternoon energy dip? You trace it back to a restless night. With consistent use, you learn to tweak your bedtime, activity, and relaxation for better outcomes.

Battery life lasts up to eight days. Charge it during your shower and wear it uninterrupted. The ring never vibrates or lights up. It collects and synthesizes without interruption. Use pre-tax HSA or FSA funds to invest in your wellness. Order the free sizing kit first. Standard ring sizes do not apply here. Your purchase includes a one-month Oura membership trial, then $5.99 monthly.
