Product Details
Titanium · IP68 Waterproof to 100m
The World's Smallest Smart Ring, Now 40% Slimmer
Oura Ring 5 tracks 50+ health metrics from your finger — sleep, heart health, stress, and activity — without ever feeling like you're wearing a gadget.
Your Wrist Wasn't Built for This
Smartwatches buzz through meetings, feel bulky in bed, and need daily charging. And the wrist just isn't where your body's signal is strongest — so a lot of that data ends up noisier than it should be.
You want the insight. You don't want the hardware getting in the way of your day.
A Ring That Reads You More Clearly
Oura Ring 5 is built with a titanium exterior, ultra-thin profile, and a pulse signal up to 100x stronger than wrist-based devices — which means cleaner data on your heart rate, sleep stages, and stress, without the bulk.
At 40% smaller than Oura Ring 4, it's the thinnest version yet, and easy to forget you're even wearing it.

What Oura Ring 5 Tracks
Sleep, without a bulky watch in the way
Sleep stages, timing, and quality tracked comfortably overnight — a ring is easy to wear to bed, unlike most wrist devices.
Heart health, made visible
Cardiovascular age and cardio capacity insights, powered by 24/7 heart rate and HRV monitoring.
Stress and resilience, in real time
Daytime stress tracking helps you spot when you're wound up before it wears you down.
Women's health, fully covered
Cycle insights, pregnancy insights, and menopause insights, based on temperature trend data.
A week between charges
6-9 days of battery life per charge, so it's a once-a-week habit instead of a nightly one.
