Oura Ring 4 (Size 13, Silver) – Advanced Health Tracking in Smart, Stylish Form

Take charge of your wellness with the Oura Ring 4, a sleek, lightweight smart ring designed to deliver advanced biometric insights for sleep, recovery, readiness, and activity — all packed into a premium titanium finish in Size 13, Silver.

All-Day Wearability & Minimalist Design

Crafted for comfort and 24/7 use, the Oura Ring 4 features a full titanium shell that is both hypo-allergenic and built to last. Its subtle, jewellery-like aesthetic makes it easy to forget you’re wearing it — whether you’re at work, at the gym, or settling in for the night.

Deep Sleep & Recovery Insights

Equipped with advanced sensors, the ring monitors key biometrics like heart rate, heart-rate variability (HRV), skin temperature, and respiratory rate to generate a Readiness Score, Sleep Score, and Activity Score. These scores help you know when to train, when to rest, and how your daily habits affect your long-term wellness.

Comprehensive Activity Tracking

More than just a sleep tracker, the Oura Ring 4 auto-detects workouts, steps, and calorie burn, then uses your readiness and recovery data to recommend smart goals tailored to you. It integrates seamlessly with popular health apps, making it a central part of your wellness ecosystem.

Impressive Battery Life & Water Resistant Build

With up to 8 days of battery life per charge, the Oura Ring 4 keeps up with your most intense weeks without frequent recharging. It also features solid water resistance — suitable for everyday use, including showers and swims — so you don’t have to worry about removing it during normal activities.
