Overview

The Oura Ring 4 Ceramic Cloud is a refined wearable that combines a premium zirconia ceramic shell with a compact sensing core. Built for daily wear, it sits quietly against the skin and prioritizes both elegance and durability. Powered by Smart Sensing, the ring adapts to your finger to deliver continuous, data-rich insights day and night.

What it tracks

  • Sleep metrics including duration and quality to help you understand nightly patterns
  • Activity data across daily movements and workouts
  • Stress indicators and heart health signals from sensitive, skin-friendly sensors
  • Women’s health metrics and cycle-related insights
  • Readiness and recovery signals to inform daily decisions

Battery life and focus

With up to eight days between charges, you can wear it without distractions—no screens or vibrations to pull you away from the moment. The app collects trends over time, helping you see patterns at a glance.

Fit, care, and upkeep

  • Recessed interior sensors provide a comfortable fit, even on sensitive skin
  • The Ceramic Polishing Pad helps keep the surface looking fresh; minor gray marks from metal transfer are removable with proper cleaning
  • HSA/FSA eligible purchases for the ring, extra chargers, and shipping

Size, color, and daily integration

Use the dedicated sizing kit to find your perfect fit before you buy, as Oura Rings come in sizes 4–15. The Ceramic Collection offers Petal, Tide, and Cloud colors to suit personal style while maintaining a sleek silhouette.

App experience and membership

New members receive the first month of Oura Membership included with purchase. After that, ongoing insights arrive via a subscription connected to your Oura App, available for Android and iOS users wherever you are.

Notes on expectations

These insights reflect possibilities supported by the ring’s sensors. They are designed to complement your routine and should be viewed as helpful signals rather than guaranteed outcomes.
