Oura Ring 4 Brushed Silver, Size 5 – Sleep, Activity & Women’s Health | 8-Day Battery | Android and iOS

Meet Oura Ring 4

The Oura Ring 4 brings a refined, all‑titanium design to everyday health tracking. Subtle and comfortable, it sits on the finger as a discreet companion that blends with daily life while gathering rich data about your habits, sleep, and rhythms. Built on Smart Sensing, this ring doesn’t just read biometrics; it adapts to you, delivering continuous data across day and night so you can observe trends over time.

With more than 50 health metrics in view—covering sleep quality, activity patterns, heart health indicators, stress levels, metabolic signals, and women’s health metrics—the ring offers a broad perspective on how you move through your days. The emphasis is on information that can help you understand your body’s signals, rather than making broad claims about outcomes. You may find value in spotting consistent patterns, comparing rest and activity, and noting how changes in routine reflect in your numbers.

Smart Sensing keeps the insights relevant by adapting to your routines and lifestyle. The absence of screens or audible prompts means you can stay present in the moment while still gaining useful context from the app. When you’re ready for a quick switch in style, you can explore multiple finishes in the Oura App and, if you own more than one ring, switch between styles with ease to match mood or outfit.

Why this could matter in your routine

Discover a holistic view of your day-to-day health with clear, wearable data. Use it to gather context for sleep, track activity decisions, or observe how stress and metabolic signals ebb and flow through a typical week. The women’s health metrics add another dimension for those who want to track cycles and related patterns.

• 50+ health metrics captured with adaptive sensing for consistent data across day and night
• All‑titanium design delivers a lightweight, durable feel you can wear daily
• Up to 8 days of battery life with no screens or vibrations to distract you
• Sizing Kit helps you find the right fit before you buy
• First month of Oura Membership included for new users, with ongoing app access
• HSA or FSA eligibility on eligible items and a seamless app experience

In real life, you might notice improved awareness of your sleep cycles, more informed activity choices, and a clearer view of how your routines affect your health signals. The goal is to provide useful patterns and possibilities, not guarantees.

How it fits into your day

The Oura Ring 4 works with Android and iOS, keeping insights accessible from the palm of your hand. Its minimalist, all‑titanium body feels light to wear and pairs with a simple app experience that lets you switch finishes across styles. Whether you’re starting your morning with a quick glance at your readiness score, logging a workout, or winding down in the evening, this ring aims to be a subtle companion rather than a distraction.

Consider it a flexible tool for personal awareness: a stylish, comfortable ring that supports a routine you choose, without promising specific outcomes. The combination of long battery life, adaptive sensing, and cross‑platform accessibility makes it a practical option for those seeking deeper context into everyday health data.
