I wore the Oura Ring 5 for a month. The headline: it’s 40% smaller than the Ring 4. And that changes everything.
I was on the subway when I spotted someone wearing the old Ring 4. It looked huge. Chunky. Almost ugly. Funny how fast you get used to something better.
The Ring 5 is Oura’s slimmest smart ring yet. It feels like jewelry first, tech second. That’s the whole point. Previous smart rings always felt like gadgets disguised as accessories. This one flips it.
Battery life improved too. Oura claims an extra day. My testing showed about six days and a few hours on the first full charge — roughly a day more than the Ring 4 gave me. Battery capacity depends on ring size though. I wear a size 6, one of the smaller options, and I’m happy with the result.
The software got some nice additions. A live activity tracker widget. A location feature for when you misplace the ring or its charging case. Women’s health tracking got deeper with pregnancy and perimenopause support.
The big new feature is GLP-1 insights. It connects your health data — sleep, stress, key vitals — to weight loss medication tracking. Dosing, side effects, weight changes. I didn’t test it personally, but it fills a real gap for people on those drugs.
Coming July 8: Health Radar. It’s an extension of Symptom Radar (the feature that predicted illness days before I got sick). This one tracks cardiovascular strain, blood pressure, and nighttime breathing over 30-day periods. Opt-in only.
The Oura Ring 5 isn’t a revolution. It’s a refinement. A thinner ring with slightly better battery and useful software updates. But that refinement makes it the most comfortable smart ring I’ve tested.
If you want a health tracker you won’t notice wearing, this is it.
