The best smart ring is the one that keeps getting easier to forget you’re wearing.
Ring 5 is 40% smaller than Ring 4 and weighs as little as 2 grams. It tracks the core Oura loop of sleep, readiness, recovery, stress, and activity directly from your finger.
Oura is also taking a much more proactive approach with the software. Starting in June, features like Health Radar will help surface patterns around nighttime breathing, blood pressure signals, and GLP-1 use.
So it gives you more early signals when something is worth paying attention to.
the part that stands out to me isnt the 40% smaller bit, its health radar. a tracker you remember to check is one thing, a ring that taps you on the shoulder about nighttime breathing or blood pressure before you thought to look is a different category. thats the real shift imo. one thing id want to know: for those proactive signals, how much is inferred on-device vs sent to the cloud? for something surfacing blood pressure and glp-1 patterns, where that processing happens matters almost as much as the insight itself
Looks interesting. I'm currently using an older Oura ring and was wondering if existing users will get these updates as well. Would love to know how much of this is software versus new hardware.
Honestly, a smaller ring is genius for people who don't like the feel of wrist watches. One thing I noticed with smart rings is the sharing of consumer data, i just wanted to know, is the app that helps connect to the ring a third party software or is the software made by your team.
Regardless this deserves a cheers of pint for the team, Great work!
Does this include an update to the software that brings full connectivity with Apple Health? Having to run the app and then a shortcut every morning just to get complete insights isn't optimal.
I really like the direction you're taking with the proactive insights. How does Health Radar know when something is just a normal fluctuation and when it's something users should pay more attention to?
@plahtela@thisisthequick@laura_furman the 40% size reduction isn't a design upgrade, it's the mainstream unlock. The ring has always been the right signal for people who don't want to wear a health statement on their wrist. Shipping this as a preorder is the right call too. Strong launch.
