OURA Ring 4 Brushed Silver Size 15 | Sleep, Activity & Women’s Health

Overview

Meet the OURA Ring 4 in Brushed Silver, a lightweight, all‑titanium ring that sits quietly on your finger while you live your day. Powered by Smart Sensing, it doesn’t just record biometrics — it adapts to your daily rhythm and delivers insights across more than 50 health metrics, including sleep quality, daily activity, heart health indicators, stress patterns, metabolic signals, and women’s health data. With up to eight days of battery life and a design you can wear from workouts to nights out, it aims to be a reliable companion you hardly notice until you explore the feedback in the app.

The ring’s minimal profile and premium finish are designed for everyday wear. It works with both Android and iOS, and if you own multiple OURA Ring 4 styles, you can switch between finishes in the app to fit your mood or wardrobe without losing your data history.

Key Benefits

• Smart Sensing tracks more than 50 metrics, including sleep, activity, stress, heart health, and women’s health indicators.
• Adaptive data collection that runs day and night without screens or vibrations, helping you stay present in the moment.
• Long battery life — up to eight days between charges — so you can wear it through workouts and evenings with minimal interruption.

Fit, Size, and Setup

Accurate sizing is essential with the OURA Ring 4. The sizing is distinct from standard jewelry rings, so start with the Sizing Kit to find your optimal fit before purchasing. A precise fit enhances comfort and the quality of the data you receive.

• Size before you buy: use the included sizing kit to determine your correct fit for best comfort and data accuracy.
• Multi-ring support: if you own two or more finishes, you can switch between them in the OURA App without losing your history.

Membership, Compatibility, and Perks

A first-month OURA Membership is included with new ring purchases. After that, the membership is a low monthly rate, and the subscription is tied to your OURA App account rather than the physical ring. The ring is compatible with both Android and iOS, putting wellness insights at your fingertips wherever you are.

• HSA/FSA eligible for the ring, additional chargers, and shipping, where applicable.
• First month included for new members; continues at $5.99 per month afterward, via the app.

What This Could Mean for You

Think of the OURA Ring 4 as a wearable that blends into daily life while providing data you can use to understand your routines. While results vary by person, many users report clearer sleep patterns, more consistent activity pacing, and a better sense of how daily choices affect overall well-being. The aim is to offer actionable, real‑world insights rather than guarantees.

In short, OURA Ring 4 combines a premium feel, robust sensing, and cross‑platform compatibility to support everyday health awareness—without demanding constant attention.
