Oura Ring 4 Brushed Silver – Sleep, Activity & Women’s Health | 8 Days Battery | Android & iOS

Meet Oura Ring 4

The Oura Ring 4 refines a wearable classic into a featherweight, all‑titanium ring designed for everyday wear. It goes beyond simple steps, offering insights from more than 50 health metrics—spanning sleep, activity, stress, heart health, and women’s health—so you can notice patterns over days and weeks without pulling out a device.

Powered by Smart Sensing, the ring adapts to you, providing continuous data both day and night. With a battery life that stretches up to eight days, you can wear it from workouts to evenings out and, often, forget it’s there—until you see the data that speaks to your routine.

Smart Sensing that adapts to you

Oura Ring 4’s sensing platform stays attuned to your body, delivering nuanced insights without the clutter of screens or vibrations. The data is designed to be read in context, helping you understand how small changes in daily habits may relate to overall well-being.

• 50+ health metrics including sleep, readiness, activity, heart health, stress, metabolic health, and women’s health
• Adaptive Smart Sensing for continuous, real‑time data day and night
• Quiet, screen‑free wear for focused daily life

Fit, setup, and ongoing use

Getting the right fit matters. Oura Ring 4 uses a sizing kit to determine your perfect size before you buy, helping you avoid returns and ensure comfort. If you own multiple finishes, you can switch between them in the Oura App to match your mood or outfit.
