I ’ve made no secret about don theOura Ring wise ringfor many years . I am by all odds a fan of the product , as is made clear by this length of service , but do n’t take this to mean I ’ll go easy on the new Oura Ring 4 .

Because of my familiarity , I ’m probably harder to yarn-dye and for sure better outfit to spot change , both good and bad . I ’ve been wearing the Oura Ring 4 for several weeks ; here ’s what I think about it .

Oura Ring 4: specs

Oura Ring 4: size and fit

Before we go into the design , let ’s talk about the sizing . The Oura Ring 4 comes in ring sizes 4 to 15 , and it ’s extremely recommended you use a sizing outfit ( cater by Oura ) before place one , as it says the sizes are slimly different from previous ring . This is utterly correct , andgetting the right sizeseems to be firmly this time around . I wore a size of it 11 third - gen Oura Ring , and the former sizing outfit confirmed I ’d postulate a size 11 Oura Ring 4 , too .

However , the actual size 11 Oura Ring 4 is looser on my fingerbreadth than the third - gen ring , and the sizing outfit shows the size 10 ring would be much too small . When my finger’s breadth is lovesome , the sizing 10 will not go on . To be clear , the Oura Ring 4 has never slip off my digit , but it does n’t have the same reassuringly secure paroxysm on my chosen finger .

The Oura Ring 4 has never slipped off my digit .

Based on the size kit options , I have no option but to live with it or swap it to another finger . I strongly recommend spend at least a full day and night wearing one of the credit card sizing kit ring and be prepared to get yourself in between sizes .

Part of why the Oura Ring 4 finger unlike from before is the complete redesign of the privileged section , where the domed stadium - corresponding nubbins have been flattened and the resin interchange by Ti . The surface is n’t all that grippy , and while there is a notch on the outside of the ring to indicate where the detector are located and assist properly set the ring on your finger , it ’s less noticeable than feeling the nubbins . While the Oura Ring 4 is no less comfortable to wear down than before , the alterations have not made it well , and although more sizes are always welcome , the actual size of the ring may mean there still is n’t the ideal Oura Ring for everyone .

Oura Ring 4: design and colors

The Oura Ring 4 is usable in six finishing : silver gray , smuggled , and atomic number 79 , plus rose gold , stealth ( a flatness Black person ) , and brush atomic number 47 , which you could see in our photo . I like the argent refinement of the third - gen Oura Ring a lot , as it was more insidious than the black and gold versions . The sweep silvery adaptation is quite dissimilar , as while the brush aspect is attractive , the surface of the tintinnabulation is highly reflective and spark in the lighter , taking away some of the canonic ash gray edition ’s subtlety .

The ring is made from Ti at bottom and out , and there ’s a thin gasket running around the edge that ’s seeable when you depend closely . depend on the size of it of your ring , its weight variegate between 3 to 5 grams , and it ’s about 3 millimetre thick . I barely mark I ’m wearing it , but there is a short point of adjustment if you ’re not used to break a ring . It also does n’t look ( from the outside ) or feel much dissimilar from the third - generation band , and I ’m proud of to say my initial business organisation over the less sonsy edges have not interpret into any quilt issues . It is chunkier than theRingConn Gen 2and theSamsung Galaxy Ring , though , and still quite clearly a piece of technology . However , the finish are genuinely stunning , while the other two are size closer to non - impudent rings .

It ’s urine resistant to 100 cadence , and while titanium is perdurable , it ’s far from being immune to scratches . Oura ’s website states , “ pocket-size scratch from even wear are normal over clock time , ” but my Oura Ring 4 has already gathered surface scratches after just a few week , and that ’s without using dumbbells or gripping metallic element or rocky surfaces .

That ’s not great , and my third - gen Oura Ring was very grave up when you looked closely after a duo of years of use . It seems the Oura Ring 4 is likely to suffer in the same way of life . If you plan on wearing the Oura Ring for tougher activities and need to keep it looking its best , consider a particular silicone polymer caseto function at these times .

Oura Ring 4: what does it do?

The Oura Ring 4 is a smart gang , but does that make it a lineal choice to a smartwatch or dedicated fitness tracker ? No , and if you ’re planning to train for a battle of Marathon or are looking for in - depth fitness and natural process tracking and data point , it ’s not give-up the ghost to do the job . It ’s a lifestyle - orientated wellness and fitness tracker with an emphasis on sleep , on-going wellness , movement , and recovery .

On the bottom of the ring are new ruby-red , immature , and infrared sensors to track gist pace and rake oxygen level , plus a temperature sensor and an accelerometer . These work differently from before , and positioning on your fingerbreadth is less authoritative . blend with a peculiar algorithmic rule that interprets the information , the app fills in any data gap to produce a more elaborated , precise picture of your health .

The app fill up in any information gaps to create a more elaborated , accurate picture of your health .

A lot of the selective information it cater is based on eternal rest tracking , which let in data point on timing , continuance , resting middle rate , spirit pace variableness ( HRV ) efficiency , rotational latency , nap stage , and body temperature . While it can track certain activities with your heart rate as you ’re doing them , the selection is limited . It can actively cross indoor and outdoor running game , cycling , and walking . It ’s inauspicious that Oura has not added more to this section , but it has add more activities the Ring can automatically recognise and then track . Thereare 40 in total , including effectiveness breeding , yoga , horseback horseback riding , and box .

So far , the Oura Ring 4 has only noticed housekeeping ( which is really utilitarian ) or walks for me , but it is also very good at not double up up on workouts , so if you track activity using an Apple Watch ( as I have been doing ) , it does n’t then suggest its own tracking too . It does auto - detect short sleep , too , but it can be fanatical here , in my experience . Finally , you may add get over for a broad range of activities after the fact , and as remark , it syncs with Apple Health and Google Fit , so exercising data cross with either appears in the Oura app .

After a scant walking test , the app can estimate V02 Max and then provide your cardiovascular eld . It also supervise tenseness levels , step , and daily calorie burn mark . Other feature article include guided relaxation method academic session , meal logging , and an AI adviser , plus a comprehensive women ’s health tracking characteristic with cycle insights , full point prevision , and integrating with the Natural Cycles app .

On paper , the Oura Ring 4 has a long list of wellness , activity , and fitness tracking uncommitted . However , it ’s important to understand that it ’s a relatively peaceful bodily function tracker , requiring piddling effort on the wearer ’s part to supervise or record these thing . Rather than being a negative , this is one of its bully strength . It means you’re able to focus more during the twenty-four hours , and then when you do open up the app , you see activities quick to confirm , plus you’re able to quickly and easily read your precondition through its datum .

Oura Ring 4: what about the app?

The Oura app receive an update to go with the Oura Ring 4 ’s release , and I go intomore particular about it in this separate article . It ’s easily one of the best apps associated with an bodily process tracker I ’ve used , as it presents its data point in a absolved and concise agency , syncs immediately , and has always been utterly true . It also provides some utile and interesting metric . I really like the young layout and the simplified computer menu , particularly the Vitals screen , which requires small more than a agile glance to sympathise to the full .

How does the app facilitate you understand your data ? Oura ’s Advisor AI chatbot help analyze it and provides advice about how and where to improve . I love that it is always in railway line with your goals , so it never feels like the app is pushing you to do thing that are n’t naturalistic . It ’s a similar floor with set day-by-day goals . For illustration , if you set it to “ Improve my wellness , ” the daily kilogram calorie burn objective is systematically high than if you choose “ do emphasis levels . ” If you favor to obviate calorie data , it can be shroud wholly from the app .

Daily scores are present in Circles at the top of the independent screenland and are easy visible . These bare - to - understand scores mean you quickly know how you ’re set for the day and can look at the data more deeply if you observe an anomaly . you may tap each Circle to see more in - depth data , and the vital organ page adds linguistic context by including your service line and averages .

The app is very good at telling you if things do n’t expect right , for example , if you ’ve log Z’s bad , have a raised temperature , or other stats are outside your normal mountain range . Wearing the Oura Ring long - condition helps it instal a service line and informs its advice .

I roll in the hay from experience . The Oura Ring ’s detector ( the third propagation version in this slip ) recognise a recent illness , and the app show my consistency temperature , HRV , and resting heart charge per unit variations straight off . Throughout this period , I used the Oura Ring ’s first-class Rest Mode , which stops it from hint activity and ensure its advice focuses on relief and recovery , but it still tracks all primal metrics so you stay informed — just without the summate emphasis of experience like you should be active .

I always experience like the Oura Ring is “ on my side . ” As someone who is n’t concerned in agitate any limits , I find out its friendly glide path really suits my life style . It does n’t institutionalize move reminders , it does n’t have notifications , and I ’m never greeted by pesky , supposedly motivational message or alerts when I get to the app . It ’s far more personal than a smartwatch , which is very meet considering the hardware is based on a patch of jewelry and made to be worn 24 hours a day .

I always feel like the Oura Ring is “ on my side . ”

There are two notable downsides to the Oura app . The first is the inability to edit the layout at all , meaning you ca n’t change the data you desire to see in the Circles , the highlighted blot on the main page , or the coloring used for graphs . The second is that if you do n’t give the monthly subscription , the app only shows your three main mark — Readiness , Sleep , and Activity — and nothing else .

Oura Ring 4: is it accurate?

If you ’re going to wear the Oura Ring 4 all the clip and ante up for the app , you want the data point it collects to be representative of your sleep , activity , and well - being . It ’s not a aesculapian machine , so none of its sensors or data has been assessed by regulatory bodies , but that should n’t intend it ’s inaccurate .

Oura made a point of stating the Oura Ring 4 ’s sensors and associated novel algorithm have improved its accuracy , but in all silver dollar , the information collected so far has not differed from the datum collect by the third - gen ring , and it all cope with what I would recognize as “ normal ” or a baseline for me . The new sensing element are supposed to avoid gaps in tape heart pace , movement , and blood - oxygen levels overnight , but I rarely see many gaps before . Checking back over the information collected by the Oura Ring 4 so far bring out no gaps at all , though .

In general , the Oura Ring counts more steps than other wearables . It ’s consistently gamey than myApple Watch Series 10 . However , when tracking a workout , in this pillowcase walking , the Oura Ring 4 records a gloomy average heart pace and less calorie burn , often by quite a margin , than the Apple Watch Series 10 . Differences are to be anticipate as they are worn in different places on your trunk , but the two are further apart from each other than I ’d care to see .

Track an out-of-door walk activity with the RingConn Gen 2 and Oura Ring 4 , and thing modify again . This clock time , the RingConn Gen 2 records a small medium nerve pace and then provides a high nutritionist’s calorie burn , although it does match the Oura Ring 4 for time spent in unlike heart pace zona . A unmediated ticker charge per unit reading material on the Oura Ring 4 , Apple Watch Series 10 , and the RingConn Gen 2 give the same figure , which is reassuring . Daily nutritionist’s calorie burn is the one metric I think may have transfer from the third - gen ringing , and the Oura Ring 4 may either be counting more accurately or undercounting , as I ’ve discover I make slightly harder to hit my daily goals .

Comparing nap , each smart ringing returned broadly similar results . The RingConn and Oura mostly agree on the sopor grade , rip oxygen , and body temperature , but they varied slightly on stay nerve pace and HRV . Plus , there were lowly differences in sleep stages . Both give a good overview of your sleep , but the Oura Ring ’s app is far higher-ranking to the RingConn ’s app for innovation and data presentation .

While none of the wear I compared matched exactly for rest and exercise , none were vastly dissimilar , and I ca n’t say one was distinctly more accurate than another . The best wellness and fitness wearable is the one you wear all the time , and this is where a smart ring really come after , as it ’s so invisible .

Long - term data provides a helpful service line , and you’re able to cursorily see alterations that may call for action on your part , whether those are body temperature variation or few steps taken each day . It almost does n’t weigh whether it’scompletelyaccurate , leave it’smostlyaccurate . All the devices here seem to fall into this family .

Oura Ring 4: battery and charging

Oura says to carry up to eight days of battery animation on a single charge , which is snug to what I have found so far . I ’ve check a assault and battery admonition appear on the sixth day of use , recommending I charge the wise ring before going to sleep . It ’s charge on a usance pedestal with a USB - hundred connector , and it ’s a orotund , heavier version of the old charging pedestal . The alloy used in its construction means it looks and feel more especial and intimately suited to life on a bedside table .

This is where I tell you battery lifespan is mostly irrelevant on the Oura Ring 4 . Provided you ’re at home base , just pop up the closed chain on its charging pedestal while you lavish or get ready for the day , and you ’ll never reach the detail where it require a full recharge . In my experience , it take about 20 minute of arc to add about 50 % to the stamp battery . This tactic makes the Oura Ring 4 very easy to be with .

Oura Ring 4: price and subscription

The Oura Ring 4 starts at $ 349 for the silver gray , gold , and black versions , then rear to $ 399 for the brushed silver and stealth versions , and to $ 499 for the rosaceous gold model . The sizing outfit price $ 10 , which is then accredit back when you enjoin the smart ring . It ’s available through Oura ’s website , Amazon , Best Buy , and other retailers worldwide .

It come with one month ’s free access to the Oura Ring app and all its data , but after that , you must pay $ 6 per month or see only the most canonical scores . If you do n’t want to make up the subscription , I do n’t think the Oura Ring 4 is deserving grease one’s palms . You should also consider the overall price of ownership before jumping into the Oura Ring 4 , as other chic rings will work out cheaper .

When I review the third - contemporaries Oura Ring , it did n’t have much competition , but that has all changed . TheSamsung Galaxy Ringand theRingConn Gen 2are both big option and donothave subscription . If you want more seaworthiness trailing options and more smartphone integration , theApple Watch Series 10,Samsung Galaxy Watch 7 , andGoogle Pixel Watch 3are all price about the same and do n’t have subscriptions either .

Is the Oura Ring 4 still the smart ring to buy?

One year ago , the Oura Ring was the only wise ring deserving purchasing , but now that the Oura Ring 4 is here , there are also two very potent alternatives to consider : the Samsung Galaxy Ring and the RingConn Gen 2 . Oura has donejustenough to bide ahead of them both , mostly due to its superb app , exculpated data , and helpful , individualized insights . The hardware has , in a room , fallen slimly behind , and I think both other smart anchor ring look sleeker and less high - tech . It ’s still beautifully made , though , and the finish represents the monetary value you pay .

However , the sizing issue , my svelte care over the data , the lack of promise additional fitness modes , and how easily it is scratched let it down . It ’s also not much of an raise over the third - coevals ring , as existing Oura Ring owners still get the newfangled app , and I have n’t seen any dramatic variety in information to suggest what it was severalise me all those geezerhood was inaccurate . When compare to the advances made by Samsung and RingConn this year , Oura is tread water with the Oura Ring 4 ’s computer hardware , observe its wind but only by a flimsy security deposit .

But as we all make out , winning is winning , and the Oura Ring 4 is a grand smart hoop with a brilliant fellow traveller app . It continues to be a dependable , trustworthy companion that I am only too well-chosen to wear all the prison term . I for sure wo n’t be for good switch to another saucy closed chain either , which should be consider a further recommendation , and I hump ensure all the historic data in the app that only comes with long - term use . Provided you ’re comfortable with the subscription , the Oura Ring 4 is still the smart band to buy , but it ’s a far closer call than ever before .
