I’ve used plenty of health wearables, however none have been a relentless presence in my life for so long as the Oura ring. I woke as much as my first evening of collected knowledge on November 3, 2020, and I’ve worn an Oura ring almost each evening since. Here is what I’ve realized from over 1,500 days value of knowledge, together with my ideas on the {hardware}, the app, and on whether or not it is all been value it.
How the generations evaluate
Oura is now on its fourth technology of rings, and I’ve used generations 2, 3, and 4. Right here’s my retrospective of every, together with what was new with every technology, and when and why I upgraded (or didn’t).
Generations 2, 3, and 4
Credit score: Beth Skwarecki
Gen 2
My first Oura ring, in late 2020, was a evaluation unit from the corporate that I returned after I wrote about it. It was a second technology (“gen 2”) ring whose actual colour, form, and measurement I don’t recall. Shortly after sending it again, I made a decision I’d like to purchase one in every of my very own, so I ended up getting a silver Stability in measurement 7, to put on on my ring finger.
The gen 2 had all of the essential options already: It may report my HRV and resting coronary heart price, make a fairly good guess at after I was awake or asleep, and make a not-so-great guess at after I was in every stage of sleep. It was widely known as the most effective wearable at sleep monitoring, though that also comes with caveats—as we’ll see.
The ring additionally recorded my respiratory price and the best way my pores and skin temperature fluctuated from evening to nighttime. Its skill to detect modifications in temperature was being touted as a potential early detection mechanism for COVID. That didn’t pan out for me both, as we’ll see under, however it was a extremely touted characteristic on the time.
Gen 3
My third technology Oura ring—a silver Heritage.
Credit score: Beth Skwarecki
When Oura got here out with the gen 3, I reviewed that, too, and the corporate beneficial carrying it on my index finger if potential. So I wore a gen 3 silver Heritage on my index finger and hated utilizing that finger for the ring. I assume I’m within the behavior of absentmindedly rubbing my nostril with the facet of my index finger, as a result of anytime my nostril was itchy, I’d attain up with out pondering and gouge myself with the ring. Once I was carried out with that evaluation, I gladly switched again to my previous gen 2 ring on my ring finger.
However then in the future, my beloved gen 2 ring died through the evening, after I may have sworn I had simply charged it. The identical factor occurred once more an evening or two later. I spotted the battery should be dying, and with luck I used to be simply contained in the two-year guarantee interval. I’ll say extra about battery longevity under, however two years seems to be a typical lifespan—and the guarantee now not covers you that lengthy. However on the time, I acquired a free substitute, and it was a gen 3 (identical measurement and colour, however Heritage form, since they now not provided the Stability) they usually threw in a lifetime subscription.
New with the gen 3 ring was the subscription mannequin: $5.99/month to have the ability to view your knowledge from the ring. (With out the subscription, you get sleep and readiness “scores,” that are ineffective with out the underlying knowledge, for my part.) House owners of gen 2 rings didn’t have to start out paying a subscription price in the event that they saved utilizing their previous ring, and there was a lifetime subscription promotion for anybody who upgraded to the gen 3 round that point.
The gen 3 ring had the identical match and inside form because the gen 2, however it now had inexperienced lights that glowed at evening, which I discovered annoying when placing my youngsters to mattress. It was through the gen 3 period that exercise coronary heart price turned obtainable. I by no means discovered it very helpful, though I used to be impressed that it auto-detected after I went for a stroll or a run. It additionally interpreted brushing my child’s hair as “dancing.” Good guess, I suppose!
Two years later, in 2024, the battery died once more. (A lifespan of two years appears to be sadly frequent.) This time my ring was out of guarantee, since Oura had switched to solely providing a one-year guarantee. However the gen 4 had simply launched, and presumably the corporate was making an attempt to eliminate their gen 3 inventory. They despatched me an actual duplicate of the lifeless one, and that’s the ring I’m nonetheless carrying right this moment.
Gen 4
The fourth technology Oura ring that I simply reviewed.
Credit score: Beth Skwarecki
I did ultimately get my arms on a gen 4 Oura ring to evaluation (spherical form, black, measurement 8 for my center finger). I wrote a comparability of the gen 3 and gen 4 rings, and a evaluation of the gen 4. The gen 4 is sweet. However after I was carried out reviewing it, I fortunately went again to the gen 3. The important options are all the identical, and I most popular the best way the gen 3 match.
With the gen 4, the ring misplaced its sensor bumps, making it smoother on the inside but in addition altering the sizing. The gen 4 is available in a wider vary of sizes, and its accuracy at selecting up coronary heart price is improved. The app was additionally redesigned round this time, the higher to handle all of the completely different options it’s acquired through the years—stress scores, resilience, chronotype, and cardiovascular age have all wanted to squeeze in, and the principle display screen now has a timeline of your day that features train classes and extra.
So should you’re maintaining depend, I’ve worn six completely different particular person Oura rings, from three completely different generations (2, 3, and 4), in three completely different shapes. If we’re counting solely rings that I’ve owned for private use, that might be one gen 2 and two similar gen 3 items, the primary two lifeless from battery points and the third a new-ish unit that’s doing effectively to date.
My favourite technology
Technologically, the gen 4 ring is the most effective of the generations, however sentimentally, the gen 2 is the one I miss probably the most. I preferred its single-pointed form, the higher to fidget with and get it oriented appropriately on my finger. And I beloved that the LEDs had been infrared fairly than seen mild. There was no inexperienced glow below the ring at evening. In the event that they introduced again a model of the Oura with out the inexperienced glow, I’d snap it up in a heartbeat.
The options Oura has added over the past 4 years have been nice-to-haves, however not sport changers. I don’t actually care about exercise monitoring; the ring doesn’t do it effectively, so I both don’t observe my exercises or I observe them with one other machine like a Garmin.

It takes a couple of weeks for any wearable to be taught your ordinary numbers, the Oura ring included. That is essential to recollect as a result of the numbers reported by the ring take advantage of sense when in comparison with your personal baseline, not to what’s a “good” rating for others. That is very true for coronary heart price variability (HRV), which is among the extra essential numbers the ring collects. An HRV of, say, 52 is perhaps excessive for one particular person, signaling that they’re effectively recovered, and unusually low for one more, signaling that they might be sick, overworked, or careworn.
Realizing that, folks generally ask on boards whether or not it’s OK to start out carrying their ring throughout a hectic time or on trip. Having been at this 4 years, I say: Begin carrying it each time. Two months from now, the precise metrics you had in your trip will likely be historical past. Heck, you may take pleasure in wanting again at them for comparability’s sake. However your baseline is constructed over time and modifications with time. It’s not one thing the ring imprints on like a duckling.
Persevering with to scroll down the As we speak display screen.

These are screenshots of what my Oura app exhibits me proper now, and in case you have a hoop you’ve been carrying for at the least a couple of weeks, you’ll see one thing comparable. All the screenshots you’ve seen to date are from the “right this moment” tab, your own home display screen if you open the app. Most of them are summaries, and you’ll see extra detailed knowledge should you faucet them, or should you go into different areas of the app. The scores on the high of the display screen—readiness, sleep, and so forth—every result in one in every of these extra detailed views.
As I’ve written earlier than, I discover that “restoration” scores are too imperfect to be helpful. Oura tries to be sensible by bumping the rating up or down primarily based on quite a lot of issues it measures. However these don’t at all times match up effectively to actuality. For instance, when the sleep algorithm was studying my REM levels poorly (extra about that under), it will at all times ding me for my supposedly dangerous sleep. And it will generally cut back my readiness rating if I went for a protracted stroll on a relaxation day, although I do know from expertise these lengthy walks assist me greater than they harm.
As an alternative, I take a look at the uncooked numbers for my resting coronary heart price and my HRV. If I’m effectively rested, and I’m recovering effectively from the stresses of coaching and life, my HRV will likely be excessive and my RHR will likely be low. It’s regular for these numbers to worsen over the course of every week as I prepare and construct up some fatigue, after which I see them get higher as soon as I’ve had a better day or two. Watching that rhythm is what helps me to know if I’m recovering effectively, or if my stress—from coaching or in any other case—is steering me towards burnout.
Whereas RHR and HRV usually observe the identical developments (excessive HRV and low RHR are “good”) I discover they react slightly otherwise. My RHR shoots up anytime my physique goes via one thing hectic. That may very well be a heavy lifting session (my RHR typically shoots up after a contest), however is also ingesting alcohol and even simply staying up late. If I’ve a fever or a migraine, my RHR will skyrocket. In the meantime, HRV may dip in response to these issues, however a excessive RHR would not at all times include a low HRV. It looks as if RHR tells me extra about how laborious one thing is hitting me, and HRV is how effectively my physique is coping with it. To be clear, that is not a scientist’s understanding of the topic, simply my very own conclusions about my physique from taking a look at this knowledge through the years.
The readiness display screen, and (proper) what you see if you scroll down.

As a result of I pay extra consideration to the uncooked numbers over the scores or little motivational messages, my favourite display screen is the one I get after I faucet on my Readiness quantity. Right here’s an instance. Discover that my Readiness scores (the blue bars within the graph on the high) have been fairly comparable every day this previous week. However I can inform that my resting coronary heart price rose over the latter half of final week, was particularly excessive (for me) on Friday, and has solely simply come again right down to a low quantity after resting a bit on the weekend. Final week was a tough coaching week, and this week I’m tapering once more for a contest, so I’m hoping to see coronary heart charges within the low 40’s and HRV numbers 95+ as my coaching ramps down this week.
Additionally, sure, a resting coronary heart price within the 40’s is fairly low. Partly that is simply how I am constructed (I’ve at all times had a low resting coronary heart price and a excessive max). Partly it is health—my RHR lowers barely after I’m doing extra train. And partly it is simply that Oura data decrease resting coronary heart charges than different units. Once I in contrast the Oura ring’s numbers with these of 4 different wearables, Oura at all times gave the bottom RHRs. When it data a 43, Fitbit may report a 50. Once more: evaluate your Oura ring’s numbers to one another, to not different folks and even different units.
Sleep staging has not been helpful (and was typically flawed)
For so long as I’ve been writing about wearables, I’ve been telling you—as sleep consultants have been telling me—that you shouldn’t belief an app when it tells you ways a lot mild or deep sleep you bought, or how a lot REM. Wearables are typically moderately good at telling how lengthy you slept, however they’re not nice at telling you if you’re in a single stage versus one other, nor do their measures of sleep “high quality” imply something that we are able to match as much as a scientific that means.
My 4 years’ value of knowledge bear this out in two essential methods. A very powerful is solely that knowledge on sleep high quality (the “sleep rating,” in Oura’s case) simply duplicates data you could possibly get by taking a look at whole sleep time.
Oura has a web-based knowledge viewer with a instrument that can present the correlation between any two variables you care to match. When evaluating my sleep rating with my whole sleep time, shock! There’s a “robust” optimistic correlation, with a coefficient of 0.77. The extra sleep I acquired, the upper my sleep rating. You don’t want a hoop or watch to let you know how lengthy you slept; the quaint manner, maintaining a sleep diary, would do the identical factor for the price of a pocket book and pen.
Darkish blue is my sleep rating; mild blue is quantity of sleep.
Credit score: Beth Skwarecki
On the subject of sleep levels, I’ve an much more dramatic manner of exhibiting the pitfalls of trusting an algorithm.
I used to be at all times skeptical of the best way Oura claimed to divide up my sleep into levels. For the primary few years, it at all times reported an implausibly low quantity of REM sleep, generally only a few minutes if you’d anticipate to see effectively over an hour. I discussed this after I interviewed a sleep scientist, and she or he confirmed that the numbers I used to be seeing in my app had been extremely unlikely to be appropriate. Oura rolled out a brand new sleep staging algorithm in the summertime of 2023, which they stated ought to enhance sleep stage accuracy. See should you can spot on this graph the day the algorithm modified:
Gentle blue is whole sleep; darkish blue is REM sleep.
Credit score: Beth Skwarecki
Out of the blue, I used to be getting a lot extra practical estimates of REM sleep (though I’ve by no means gotten a sleep examine in a lab, so I can’t verify whether or not they’re appropriate.)
We are able to even see the place the “new” REM sleep got here from. Not from awake time, or from mild sleep, which had been each reported in comparable quantities earlier than and after the change. No, the algorithm appears to have taken a few of what it beforehand thought-about deep sleep, and recategorized it (perhaps appropriately) as REM sleep. The deep sleep graph appears to be like like the other of the one above. I felt validated in my complaints that it should not be selecting up my REM sleep correctly. I additionally gained a lesson in simply how a lot we’re on the whims of the algorithm.
It by no means predicted after I acquired sick
I don’t suppose anyone who buys an Oura ring now is searching for an early detection system for after they get sick, however this was a significant speaking level for the corporate (and amongst customers) for a short while. In 2020 the corporate labored with UCSF on the TemPredict examine to see if the ring may let healthcare employees know when to check for COVID. Boards that mentioned the Oura ring would sometimes characteristic posts from individuals who had been capable of see indicators of poor restoration within the app earlier than they realized they had been sick.
However my very own expertise didn’t bear that out. Once I had been carrying the ring a couple of month, I acquired sick. It was in all probability a daily chilly or flu, however my COVID check got here again inconclusive(?!?) so I by no means did discover out for positive. Regardless of the sickness, my Oura didn’t understand I used to be feeling something lower than stellar till three days after I began feeling feverish, drained, and icky.
I acquired COVID for positive in June of 2022, and it’s fascinating to try my Oura ring knowledge from the week I examined optimistic. I recall signs beginning on that Thursday or Friday, June 2 or 3. It was on Sunday, June 5, that I felt terrible sufficient that it occurred to me to take a COVID check, which was optimistic. You may see on this graph that my nighttime temperature peaked on June 7, two days after I examined optimistic. My readiness scores had been all nice—above 80—till that day. Each different metric I can suppose to examine was regular as effectively, together with my HRV, common resting coronary heart price, lowest resting coronary heart price, and respiratory price.
Darkish blue is temperature, mild blue is readiness rating (out of 100).

Since then, I’ve solely had minor colds and sniffles. Whereas I’ve by no means had Oura drop any hints earlier than I acquired sick, I have discovered it validating to see my RHR rise and readiness drop after I’m kinda-sorta feeling below the climate. That tells me that there actually is one thing occurring, even when it doesn’t rise to the extent of a full-blown fever or coughing match. However, once more, I don’t get that validation till after I’ve began feeling crappy.
Simply me? I seemed up the outcomes of the TemPredict examine. The researchers stated they had been in a position to make use of an algorithm to inform who was sick, and that the day the algorithm acknowledged the sickness was on or earlier than symptom onset in 65% of instances, and on or earlier than a optimistic COVID check in 80% of instances.
That’s, to be trustworthy, not all that helpful! The thought was to foretell sickness earlier than these dates, so “on or earlier than” is lumping within the instances the place it may act as an early warning system with instances the place an individual already knew they had been sick. And, clearly, the algorithm missed lots of people.
Oura gave these outcomes a optimistic spin. The headline discovering was that when the algorithm labored, it predicted sickness 2.75 days earlier than a optimistic check. However symptom onset was 1.98 days earlier than a optimistic check, so even the algorithm’s prediction—which was not revealed to customers within the app, solely examined by scientists—would offer you lower than a day’s discover earlier than you began feeling sick.
Oura referred to as these outcomes “preliminary” on the time, however the staff has not revealed anything on sickness detection since then, at the least not that I can discover.
However Oura did ultimately launch Symptom Radar, a characteristic that rolled out to Oura customers in December of 2024. I haven’t gotten sick since then, so I can’t touch upon whether or not the algorithm would be capable of discover something I didn’t. Backside line: I really feel assured in saying the promise of sickness prediction has fallen flat. If it really works for a couple of folks, and in the event that they take pleasure in getting a day’s discover earlier than they begin feeling sick, cool. However that is not precisely useful in any sensible sense.
Sturdiness

While you purchase a $300+ piece of knickknack, you anticipate it to final. Oura homeowners (and potential homeowners) are at all times asking on boards how simply the ring scratches, so right here’s a photograph. That is the gen 3 ring that I wore for 2 full years. You’d need to look intently on the high floor to see the little scuffs and scratches, however there are a couple of. The underside floor, the place the ring would contact issues I’m holding, is extra scratched up for positive. This doesn’t trouble me, since I see the Oura ring as extra of a instrument than a pristine style piece. Others might really feel otherwise.
Oura rings have a titanium exterior, and apparently I’ve a comparability for that—my marriage ceremony and engagement rings are additionally titanium. All three get loads of day by day put on. My marriage ceremony ring’s scratches are delicate; the Oura ring’s are rather more apparent by comparability.

Battery longevity
My greatest disappointment through the years has been the battery longevity. Not the battery life—the ring goes most of every week between fees with none downside. However I’m speaking about how a lot use you get out of the ring earlier than it stops holding a cost.
My gen 2 ring got here with a two-year guarantee, and I recall seeing a Reddit publish reminding folks to examine their battery well being earlier than the guarantee was up, since some customers had discovered that their battery died proper across the two-year mark. I forgot all about that, after which it occurred to me. Thankfully, I used to be simply barely within the guarantee interval, and acquired my substitute. Two years later, the identical factor occurred once more, though Oura had wised up and stopped providing a two-year guarantee. The guarantee is now one 12 months and doesn’t cowl battery points, at the least within the U.S. (A two-year guarantee is required by regulation within the EU.)
I lucked out once more with my second substitute, for the reason that gen 4 had simply launched. I recall being given the selection of a $50 low cost on a brand new gen 4, or a completely free gen 3. I went for the gen 3, however didn’t have an choice to ask for a special form or colour. They simply shipped me a reproduction of my previous ring, in a baggie (no charger).
I can’t complain about getting three rings for the value of 1. That stated, ought to I really want three rings in 4 years? There are many five-year-old Apple Watches and Garmin watches on the market that price round $400 initially. You’ll anticipate a $300+ Oura ring to last more than two years. However examine the subreddits and boards, and ask any long-time Oura ring consumer you already know. Two years is fairly typical for the gen 2 and gen 3 rings. (It’s too early for a verdict on the gen 4.)
Should you’re the type of particular person to improve as quickly as a brand new mannequin is out, this will not matter an excessive amount of—Oura has been releasing new rings on roughly a two-year cycle. However it’s best to know that you just’re not shopping for one thing that can final for years and years. I noticed somebody on a discussion board who was eager about getting an Oura ring as his precise marriage ceremony ring. Not a superb choice should you’re going to be sentimentally hooked up to that particular, bodily ring.
The Oura is the lowest-maintenance wearable I’ve met
Why have I worn this ring almost each evening for the final four-plus years? As a result of it’s so dang straightforward. I don’t want to start out or cease something on the ring itself or on an app. I don’t must put on it for exercises. It doesn’t take up beneficial wrist actual property, so even when I’m carrying a Whoop, Fitbit, Apple Watch, and Garmin watch on the identical time and griping about it as I strap all of them on for bedtime, it doesn’t trouble me in any respect to have the Oura ring on, too.
Even throughout occasions I used to be paying extra consideration to different wearables, I saved the Oura ring on. As soon as every week or so, it would pop up a notification on my telephone asking me to cost it earlier than I am going to mattress. And so long as I open the app a couple of times every week to make sure it’s syncing, I do know my knowledge is saved safely in a spot I can take a look at it later.
Charging is low-maintenance, too. I maintain the Oura ring’s charger on my nightstand. I’ll cost my ring after I head to the health club, and even when I overlook to place it again on immediately, I’ll see it on the nightstand after I’m stepping into mattress. The one factor I discover inconvenient about charging is the dearth of a safe charging case or perhaps a low cost spare nightstand charger I may convey with me after I journey. That stated, the ring holds sufficient cost that I can get via a weekend journey with out charging, so long as the battery was full after I left.
My Oura ring knowledge didn’t reveal any deep secrets and techniques about restoration
By way of the big-picture payoff of carrying the ring, I first must say what it didn’t give me. My unique curiosity in sleep and restoration monitoring (with the Oura or in any other case) was to see if there was a method to predict my efficiency within the health club. Cardio train within reason straightforward to get a deal with on, however weightlifting is completely different.
I compete in Olympic-style weightlifting (the game of the snatch and the clear and jerk). The weights are heavy, however the lifts additionally require exact approach and coordination. Some days you may snatch 60 kilos, some days you’re fortunate to make 53. My coach patiently defined, on many events, that if I’m in the midst of a troublesome coaching block, fatigue can be masking a few of my skill. This pops up in surprising methods—if I simply had a terrific efficiency on Saturday, perhaps hitting a brand new PR (private report), I would battle on Monday as a result of I am having a “PR hangover.” Coaches and lifters have identified this for many years, if not centuries. However it’s nonetheless laborious to foretell precisely if you’ll really feel uncoordinated versus if you’ll carry out effectively.
I hoped that metrics like coronary heart price variability and resting coronary heart price would give me a window into what was occurring below the hood. However it didn’t fairly work out that manner. Whereas usually I’d have higher days when my HRV was excessive and my RHR was low, that wasn’t one thing I may depend on.
There have been loads of occasions I had a terrific day within the health club or on the competitors platform, regardless of mediocre restoration metrics. And the reverse occurred, too. In the end, you don’t know the way you’ll really carry out within the health club till you really get there and do some lifts—efficiency can solely be judged after the very fact. I stated from the beginning that I’d by no means belief a tool greater than I’d belief my very own physique, and I’m glad I saved that promise. If I had skipped or rescheduled exercises primarily based on my “readiness” or different metrics, I’d have missed out on good coaching.
Restoration metrics are a superb actuality examine on the large image of coaching and life
So if the metrics from the Oura app didn’t reveal any deep secrets and techniques or make me change my coaching, why do I nonetheless keep watch over them, 4 years on? As a result of they provide me delicate hints about what’s occurring in my physique, and produce the large image of my coaching and life stresses into focus.
I’ve a way of what HRV and RHR numbers I see after I’m well-recovered and coaching goes effectively. I even know the way a lot my resting coronary heart price tends to drop after I’m within the behavior of doing plenty of cardio coaching (solely about 3-4 beats, however that’s sufficient to be noticeable).
I do know what it appears to be like like when my coaching stress has elevated however I’m coping with it effectively: a barely elevated RHR, however HRV continues to be normally fairly excessive. I do know what it appears to be like like after I’m careworn and burned out: excessive RHR, low HRV. I do know that if I’m managing my fatigue fairly effectively all through the week, I’ll see the numbers reset on the weekend as my relaxation days or straightforward days permit my physique to catch up. And I’ve come to know these numbers via evaluating them to how I really feel—not by trusting a rating or a graph or an evidence within the app. It’s a must to take possession of your new self-knowledge, and be taught, not simply hear.
Would I’ve gotten simply nearly as good an understanding of my physique and my coaching with out the ring? In all probability, however I’d anticipate much more psychological ups and downs. I tend to go too laborious and never understand how a lot I’m pushing myself, after which to beat myself up when issues aren’t going in accordance with plan. The information I get from my ring helps to present me a actuality examine on what my physique goes via, whether or not it’s an under-the-radar chilly or a troublesome coaching block that compounds with different stress I’m getting from life. I assume the ring has taught me slightly little bit of self-compassion. That’s helped me immeasurably, although it’s not the lesson I used to be anticipating to be taught from monitoring all this knowledge.
