Design & Construct

- Now consists of extra titanium in design
- New Ceramic mannequin added
- Sensor platform sits extra discreetly
The Oura Ring’s enchantment is partly all the way down to how good it appears and that doesn’t change with the Ring 4. There are six end choices in whole. That’s silver (pictured), black, brushed silver, stealth, gold and rose gold. The silver and black choices are the most cost effective to go for with gold and rose gold fashions coming in the most costly.
Replace October 2025: Oura has introduced a brand new Ceramic version of the Ring 4 which is available in 4 colors – Cloud, Tide, Petal and Midnight (see under). It’s made out of zirconia ceramic which Oura says is extremely light-weight, but in addition “surprisingly sturdy” with a Mohs hardness scale score of 8.5 out of 10.
The Ceramic version of the good ring brings a extra enjoyable and vibrant take, which only a few manufacturers supply and you may even use two or extra Oura Ring 4s, alternating relying in your scenario or outfit. Oura does warn that the ceramic can scuff, taking up the color of soppy metals like dumbbells and cookware so that you may wish to take it off at sure occasions.

Some of the notable modifications is the etching on the surface of the ring to function a visible reminder that the ring must be worn with the sensors sat in opposition to the within of your finger. It’s one thing that Samsung does on its Galaxy Ring good ring as nicely, which is beneficial however breaks up an in any other case modern ring.
These sensors hidden on the underside of that etching now sit extra flush with an inside that’s now absolutely encased in titanium. It makes carrying the ring much less noticeable and a bit extra snug to put on than the Oura Ring Gen 3.
There’s now only a absolutely round model obtainable that does preserve it in keeping with the look of rival good rings. Oura’s Ring nonetheless appears totally different sufficient and has a typically nicer end to assist it stand out from different rings – Oura customers will probably be pleased with the modifications.
It nonetheless picks up scratches, which Oura has now talked about on its web site will occur with common put on. It’s not been as dangerous because the very scratch-friendly Ultrahuman good ring, however Samsung’s Galaxy Ring does a greater job of warding off these seen indicators of wear and tear.

When it comes to sizing, I used to be beneficial to get a sizing equipment because the design modifications with the Ring 4 might imply a change in match from the Ring Gen 3. I ended up going with the identical measurement, although that’s not essentially going to be the case for all, since there have been some alterations to the {hardware} and design.
The Ring 4 additionally gives a wider vary of sizes than the earlier iteration. You’ll be able to go for 4 by to fifteen – the Gen 3 is simply obtainable in sizes six to 13. Oura recommends customers put on a take a look at ring for not less than 24 hours, as fingers can change sizes all through the day and evening.

There’s some new metrics added and maybe extra crucially, a brand new optical sensor platform that opens up extra sign pathways than the earlier Oura Ring to enhance monitoring accuracy. Oura additionally guarantees to enhance monitoring for various pores and skin tones, finger shapes and when the ring strikes round your finger.
It’s going to observe your steps, monitor sleep, stress, temperature, day by day coronary heart charge and it’s all geared in direction of powering Oura’s Readiness metric that can inform you whether or not you’re in tip-top form to tackle a strenuous day or you must contemplate taking issues straightforward.
That Readiness metric is simply nearly as good as the information that powers it. So ensuring you’re getting correct coronary heart charge, sleep and train information to guarantee that Readiness quantity will be helpful.
The most important points on the Oura Ring Gen 3 lay with the guts charge and its potential to think about train information, two issues Oura has made enhancements with, particularly on monitoring coronary heart charge, throughout train and higher compensating for when the sensors won’t be sitting within the optimum place.
Mike Sawh
For train, Oura seems to simply accept its limitations to some extent and whereas it will possibly routinely detect workout routines in a fairly dependable trend and does provide the potential to file coronary heart charge from exercises when prompted within the app, I nonetheless don’t belief it sufficient to trace all of my train coronary heart charge extra reliably than a devoted coronary heart charge monitor chest strap. I acquired some good information, significantly when utilizing it for regular paced exercises, so should you’re not doing all-out HIIT lessons, you may simply get the great coronary heart charge information you crave.
That assist places an even bigger emphasis on the flexibility to hook up with Strava the place I nonetheless tracked my exercises from a Garmin or Apple Watch and helped to supply extra dependable information factors for Readiness metrics, which informed me an identical story to the Coaching Readiness insights on a Garmin and the Vitality scores on a Samsung Galaxy Ring.
Sleep monitoring continues to be a power for Oura and stays one of many largest causes to purchase this ring. After I in contrast core sleep information like whole sleep, resting coronary heart charge and sleep stage breakdowns with the Samsung Galaxy Ring and Garmin’s, the information regarded sturdy, dependable and insightful.

Oura will even take note of your daytime stress and resilience, so I might clearly see from the app the place I used to be veering to extra hectic intervals of my day with helpful explanations offered why it will possibly typically be on the rise at sure components of the day.
There are a bunch of different options right here to encourage good habits or present extra insights. You’ll be able to tackle an experiment to scale back caffeine consumption, see your cardiovascular age and make use of the symptom radar, which got here in helpful when testing it out first with the Oura Ring Gen 3.
Cycle monitoring is included within the app, although Oura is presently the one good ring producer to be supported for the FDA-approved app Pure Cycles, which can be a key swing for a lot of consumers.
Oura’s companion smartphone app has definitely develop into loads busier than when it first launched. Crucially, it nonetheless makes these options glanceable and interesting, which is the place another good ring makers barely falter.

You’ll be able to get pleasure from as much as eight days of battery life with the Ring 4, although that quantity can rely on ring measurement and the monitoring options in use.
My measurement eight is likely one of the smaller ring sizes obtainable, and that appears to reflect the kind of battery life I loved. Sometimes, it was nearer to 5 days than eight days, with a nightly drop-off of 14-15%, exhibiting you ways a lot information crunching it does in a single day.
Should you activate the blood oxygen sensing, there’s a extra dramatic drop in battery life. Should you can reside with out that, you’ll get pleasure from considerably extra battery between costs.
That’s an enchancment on the Ring Gen 3, which in the identical measurement lasted sometimes lasted simply a few days. Issues are entering into the proper path, it’s simply not the chief on battery entrance.
When it’s time to cost, you continue to have a charging cradle that you could drop the ring onto. Relying on how low you might be on battery, charging can take anyplace from 20-80 minutes. That’s the identical because the Oura Ring Gen 3.
The look of the cradle is a little more excessive grade than the earlier one, although I do suppose the moveable charging circumstances obtainable with the Galaxy Ring and RingConn Gen 2 make for higher good ring charging setups.
Replace October 2025: Oura has introduced a charging case for the Ring 4, which you’ll be capable to carry round like many rivals. It could possibly cost the ring a powerful 5 occasions and costs again up in 90 minutes through USB-C – the identical period of time it takes for the ring to cost inside. The case is made out of recycled aluminium on the surface and prices $99 and will probably be on sale within the US and ‘chosen markets’ later in 2025. You’ll want a case which matches the dimensions of your Oura.
