Product details

Discover Oura Ring 4

The Oura Ring 4 blends a sleek, all-titanium body with Smart Sensing to track daily health signals without getting in the way. In a brushed silver finish, it sits lightly on your finger, ready to capture data for more than 50 metrics including sleep, activity, readiness, heart health, stress, metabolic patterns, and women’s health markers.

With up to eight days of battery life and no screen or constant notifications, you can wear it through workouts, commutes, and nights out and still forget it’s there—until a compliment or a subtle glow from the app draws you in.

Smart Sensing that adapts to you

Smart Sensing powers continuous measurements that feel personal. The ring learns from your rhythms to deliver daily insights that highlight trends over time, not just isolated numbers.

  • Sleep quality and duration insights to guide rest without being prescriptive
  • Activity and readiness signals to help you balance effort and recovery
  • Heart health, stress, and metabolic signals presented as actionable patterns
  • Women’s health metrics that offer context across cycles and trends

Design, fit, and everyday versatility

Built from durable titanium with a brushed silver finish, the ring is designed for all-day comfort. The sizing kit helps you find your perfect fit before you buy, reflecting Oura’s size-before-you-buy approach.

  • Unique sizing rather than traditional jewelry sizing to ensure accuracy
  • Up to 8 days of battery life, keeping your routine uninterrupted
  • Multi-ring support lets you switch finishes between styles in the app
  • HSA/FSA eligibility for eligible purchases

What you get and how it fits your life

New members receive the first month of Oura Membership included with purchase. The ring works with Android and iOS, syncing insights to your phone so you can review trends anytime, anywhere.

Consider Oura as a companion that quietly maps patterns you care about—without promising outcomes—so you can explore possibilities and tailor routines to your own needs.
