Oura Ring Generation 3 review: a relationship for the long term


In 2020, it appeared just like the Oura Ring was all over the place. Researchers had been finding out whether or not the sensible ring (and different wearables) may sooner or later detect sickness, and proper on cue, the NBA introduced it purchased 2,000 Oura Rings to watch athletes. Prince Harry has been a fan for years, and celebrities like Jennifer Aniston and Kim Kardashian West have additionally been noticed carrying the sleep tracker. That’s already plenty of buzz for a distinct segment gadget, however the third-generation Oura Ring, which launched in late 2021 and remains to be the present model, additionally provides formidable new options like interval prediction and blood oxygen. The query is whether or not it’s value committing to a $299 sensible ring that now requires a month-to-month subscription.

How we fee and evaluation merchandise

Nobody will understand it’s a wise ring

For a hoop with such trendy devotees, it’s fairly plain. My gold Heritage evaluation unit isn’t too far off from what Frodo schlepped to Mordor. It additionally is available in silver and black in addition to a matte black model known as “stealth.” Since launch, Oura’s additionally launched a snazzier Oura x Gucci model that prices an eye-watering $950 in addition to a totally spherical Horizon design that prices $349. The latter is definitely a neat feat of engineering, because it requires a versatile battery to accommodate the form. (The Heritage design has a flat high that homes the battery.) Functionally, the Heritage and Horizon are the identical, and having tried each, the design variations are virtually negligible.

Except you’ve received the Gucci model, you most likely gained’t flip heads. The ring is ideal at mixing seamlessly into your life. It doesn’t catch in your garments, it’ll by no means buzz if you get notifications, and it’s far more snug than carrying a smartwatch 24/7. Most days, even I forgot it was a wise ring. 

This type of disappearing act isn’t any simple feat. The brand new Oura Ring packs in 4 extra temperature sensors for a complete of seven, a brand new inexperienced LED coronary heart fee sensor, and an SpO2 sensor for monitoring blood oxygen ranges. That’s on high of the battery and accelerometers. (When you take a look at the within of the ring, you possibly can catch a glimpse of how tiny these sensors are.) So whereas the ring is somewhat wider than I’d want — particularly for petite fingers or smaller palms — it’s a good tradeoff contemplating the place the tech is at in the present day.

Whereas it’s spectacular Oura crammed this a lot into such a small type issue, it’s not with out its quirks. Not like a traditional ring, you must examine if the sensors are positioned accurately if you need probably the most correct metrics. (That is simpler to do with the Heritage model, because it has a flat high. The Horizon has a dimple the place the sensors are, however I typically didn’t discover when the sensors had been misaligned.) Because you’re carrying all of it day and night time, you additionally must be diligent about maintaining the sensors clear. Match can also be essential because it isn’t adjustable. You not often must measure your wrist to purchase a smartwatch, however for the ring, you first have to attend two to seven days for a free sizing package. Oura then recommends you take a look at a dummy ring for at the least a day earlier than inserting an order.

The Horizon model has a delicate dimple so you possibly can inform the place the sensors are. You’ll know you’re carrying it accurately if the dimple aligns with the underside of your finger.

Like a smartwatch, the ring must be charged. It takes about two hours to stand up to one hundred pc battery. When the Gen 3 first launched, and earlier than Oura launched its extra formidable well being options like SpO2 monitoring, I typically received near Oura’s estimated seven days of battery life. Now that I’ve enabled SpO2, I get round three to 4 days. That’s not horrible, and the Oura app is fairly good about sending reminders to cost earlier than mattress. However I’ve misplaced just a few nights of sleep knowledge right here and there as a result of I both missed the notifications or was too drained to cost the dang factor earlier than mattress.

Sleep and restoration monitoring

The Oura Ring payments itself as a sleep and restoration tracker, and that’s what it does greatest. The app facilities round three scores: readiness, sleep, and exercise. Every is calculated primarily based on the guts fee, temperature, and exercise knowledge collected by the ring. A excessive rating is sweet, whereas a low rating means you would possibly must take it simple or reevaluate your habits. That’s the gist, and you can fortunately ignore all the opposite knowledge it throws your means. However if you need extra perception, put together to do plenty of studying.

Take your sleep rating. Oura determines that by taking a look at elements akin to whole sleep, REM sleep, and deep sleep — pretty typical sleep metrics that different wearable units present, too. Then there are additionally extra novel metrics like “timing,” which refers back to the midpoint of your whole sleep falling between midnight and 3AM. Likewise, your readiness rating makes use of one thing known as “restoration index,” or the time it takes in your resting coronary heart fee to stabilize throughout sleep. Fortunately, every of those metrics comes with little explainers as to why they matter. 

Each the Oura Ring Gen 3 (center) and Gen 2 (left) are a lot thicker than regular rings.

These three scores are on the core of the Oura expertise. Nonetheless, the third gen’s new sensors add much more knowledge to the combination. Beforehand, the ring solely measured your coronary heart fee when sleeping. However with the brand new inexperienced LED, now you can observe your daytime coronary heart fee. That introduces new phrases, like restorative time, and graphs of coronary heart fee traits. Restorative time refers to durations of rest the place the ring detects your coronary heart fee is low and, unusually sufficient, your palms are heat. (Oura’s chief of product, Chris Becherer, says it’s because pores and skin temperature will increase if you’re extra relaxed.) There’s additionally a information so you possibly can interpret what patterns you’re seeing. For example, a low, flat daytime coronary heart fee sample is named an “Open Ocean” and exhibits you’ve had a chill day. In the meantime, a hammock-shaped coronary heart fee curve signifies your physique recovered nicely through the night time. It’s loads to absorb, however Oura will get kudos for together with each bite-size and in-depth explanations to present you extra context. 

Within the yr and alter for the reason that Gen 3 launched in late 2021, Oura has continued so as to add new metrics. The most recent is Oura’s tackle circadian rhythms, that are characterised within the app as your chronotype and physique clock. Chronotypes are decided after roughly three months of information and can inform you whether or not you’re an early chook or an evening owl. (Although not in these actual phrases.) The physique clock function is a visualization of whether or not you’re going to mattress on the splendid time in your chronotype. I occur to be an “early night kind,” which, primarily based on Oura’s clarification, I’d characterize as a form of night time owl lite.

However is it correct? Daytime coronary heart fee monitoring was consistent with different trackers. In random spot checks, it was inside 5 beats per minute of what I used to be getting on my Apple Watch Collection 7. There have been instances once they weren’t in sync, however that often evened out after just a few seconds. Mainly, the Collection 7 will get you a sooner real-time coronary heart fee, however Oura’s day by day knowledge is offered in a extra digestible format. I’m additionally tickled that the Oura Ring noticed my nightly Pokémon periods as restorative time. 

Restorative time is a brand new metric that’s a part of daytime coronary heart fee monitoring. The Discover tab can also be new.

As for sleep monitoring, some wearables I’ve examined have struggled to inform after I’m awake at 4AM as a result of the cat is yowling on the moon. For my fellow insomniacs: some trackers rely these sleepless hours spent staring on the ceiling as sleep. I didn’t have that downside right here. It was capable of inform after I left the mattress for midnight snacks and accurately recognized after I was awake however attempting to fall again asleep. I can’t inform you how correct the sleep phases knowledge is, nonetheless, as I don’t have entry to medical gear. However after I examined it at launch, my sleep knowledge did correspond to what I received on the Sleep Cycle app on my cellphone and persistently outperformed the Withings ScanWatch. Within the months since, I really feel solely Fitbits and the Whoop 4.0 actually gave the Oura Ring a run for its cash so far as wearable sleep trackers go.

Oura has been beta testing , which it says is extra correct and higher corresponds with gold-standard polysomnography. I’ve been toggling between the present and new algorithms, however I’m hesitant to say which one I discover extra correct till the ultimate model is on the market. What I can say is there’s a noticeable distinction between the 2, and the brand new algorithm tends to say I get up extra through the night time.

Once I reviewed the second-gen Oura Ring, the readiness rating was hit-or-miss. Some days, it instructed me to take it simple after I felt superb. Others, I used to be a strolling prepare wreck and was instructed to problem myself. This time round, nonetheless, it appears to have gotten higher at recognizing bodily stress. I used to be sick for per week, and my readiness scores, which had been within the excessive 70s–80s, plummeted to the 50s–60s. I additionally appreciated the flexibility to activate a “relaxation mode,” which shuts off your exercise rating and prioritizes your readiness and sleep. Extra health trackers ought to observe Oura’s lead. 

You’ll be able to select whether or not you need your metrics to be simple to digest or if you wish to go deep.

Alongside that line, Oura’s exercise rating emphasizes weekly exercise over arbitrary day by day objectives. It’s okay in the event you’ve been chained to your desk all day — you gained’t get shamed for it. As a substitute, your rating will solely begin to dip in the event you don’t meet your objectives three or extra days in per week. It additionally accounts in your coaching load and can modify your day by day calorie burn goal relying in your readiness rating. 

One other neat function is quantified meditation periods. I usually move on woo-woo guided mindfulness options, however Oura caters to knowledge nerds. After every session, you possibly can view the way it impacted your coronary heart fee, coronary heart fee variation (HRV), and pores and skin temperature. Simply this week, the corporate additionally added a brand new Discover tab to the app, which organizes audio and video content material and supplies extra instructional studying.

What’s new?

Though the Gen 3 had SpO2 sensors from the get-go, blood oxygen monitoring wasn’t initially obtainable on the Gen 3. It lastly arrived in an replace in summer time 2022, and it’s one of many higher wearable blood oxygen options I’ve examined. Although to be honest, the bar is fairly low.

That is how Oura presents its SpO2 knowledge, although I’ve personally by no means gotten the “Listen” ranking.
Picture: Oura

When you allow the function, Oura will measure your blood oxygen in two methods. The primary metric is your commonplace common nightly SpO2 share. Something above 95 p.c is taken into account regular. The second metric is one thing Oura dubs respiratory regularity. That is what number of variations in your blood oxygen ranges had been detected throughout sleep. Variations might be an indicator of respiratory disturbances, and the less the higher. Each Fitbit and Withings have related SpO2 options, so it’s not like it is a revolutionary take. Nonetheless, I discover that Oura’s presentation is probably the most digestible, and its instructional studying really tells you the best way to interpret your outcomes.

That mentioned, SpO2 monitoring comes with a serious tradeoff in battery life. And whereas I like Oura’s SpO2 implementation higher than the spot checks you’ll discover on an Apple Watch or Samsung smartwatch, it’s nonetheless not a very helpful metric. I’m a wholesome grownup, and within the roughly eight months I’ve been testing this function, I’ve solely gotten Optimum and Good respiratory regularity scores. The bottom my common nightly SpO2 has been is 96 p.c. I don’t have a lot use for this function, and it’s not likely value shedding half my battery life for. It may be completely different if I suspected I might need sleep apnea, however even then, this isn’t meant to be a diagnostic function in any capability.

Interval predictions are primarily based in your temperature, consumer suggestions, and the calendar technique. Oura recommends at the least 60 nights of information to get extra correct outcomes. Within the app, you possibly can see a bar graph of how your temperature knowledge modifications over the course of your cycle in addition to your historic interval knowledge. A number of days earlier than your interval is anticipated to begin, you’ll get an alert inside the app. When the app believes your interval ought to have began, it’ll additionally immediate you to log your knowledge.

Interval predictions are in beta, however you get advance notifications primarily based in your temperature.

I’d like to inform you whether or not these predictions are correct, however Oura’s interval predictions aren’t suitable with contraception. The identical is true in the event you’re going by way of different hormonal circumstances or taking sure medicines. This isn’t a knock towards Oura — it’s factor, from an accuracy standpoint. Apple additionally contains a number of of those as elements that disable its temperature-based Cycle Monitoring options like retrospective ovulation estimates. It’s best to simply be conscious of those limitations.

(A fast apart: you possibly can at the moment use the Oura Ring’s wearable temperature knowledge with Pure Cycles’ FDA-cleared digital contraception function. I haven’t examined this function, so I can’t attest to how nicely it really works.)

The Gen 3 additionally provides exercise coronary heart fee monitoring, however it’s the least spectacular of the brand new well being monitoring options. For starters, it’s fairly bare-bones and solely helps operating, biking, and strolling. The report display screen doesn’t present any metrics — which is sweet for distraction-free train — however will present a abstract of your stats, route, splits, and coronary heart fee as soon as the exercise is completed. That’s superb if all you care about is informal exercise monitoring. however I discover it extra helpful to import exercises from Apple Well being and Google Match (or any app like Strava that integrates with these APIs).

That brings me to my predominant criticism of the Oura Ring. When you’re an athlete or need to keep related with out your cellphone, this gained’t be sufficient by itself. For me, the perfect means to make use of the Oura Ring is as a secondary tracker. Most smartwatches aren’t nice at sleep and restoration monitoring but, so the Oura Ring takes care of that. In the meantime, those self same smartwatches make up for the Oura Ring’s lack of notifications and detailed exercise monitoring. However I’m utilizing my wearable reviewer privilege right here. Shelling out $300 to $350 plus a month-to-month $6 payment for a secondary tracker? On this economic system? That’s a tough ask.

A future-focused wearable

Once I first began reviewing the Oura Ring Gen 3 in late 2021, half the options weren’t out but. And as somebody who covers this firm, I do know that there are a number of different options that Oura’s nonetheless engaged on that we might not see for years. I don’t know when the brand new sleep stage algorithm can be deemed prepared, and who is aware of after we’ll see what comes out of Oura’s analysis into sickness detection and pregnancy predictions. I spoke with Becherer and former Oura CEO Harpreet Rai earlier than the Gen 3 launched, and each emphasised interval predictions are a child step towards extra formidable girls’s well being options and analysis. Clearly, Oura’s trying far off into the way forward for wearables, and it’s relying on its prospects to really feel just like the wait is value it.

It additionally means a lot of what makes the ring cool could also be invisible to the typical individual. Becherer confirmed that the brand new sleep algorithms are a back-end replace, and also you gained’t see any UI change within the app. Your knowledge will merely be extra correct. For every of Oura’s obtainable options, you’ll get the very best outcomes provided that you put on it daily for months. That’s an enormous dedication, and in the event you’re going to purchase in, it must be one thing you’re okay with.

The ring comes with somewhat USB-C charging stand.

It doesn’t assist that, with the launch of the Gen 3, Oura switched to a subscription mannequin. The corporate mentioned it did so exactly as a result of it has such formidable plans on this area. The analysis that Oura (in addition to Apple and Fitbit) partake in is dear, and more and more, one-time {hardware} gross sales aren’t keeping the lights on for smaller corporations. It’s additionally the place wearables are headed. Fitbit has Fitbit Premium, Apple has Health Plus, and Whoop — one other restoration tracker — requires a $30 month-to-month subscription (although yearly subs are cheaper).

In comparison with these, Oura’s membership is on the inexpensive facet. You get six months free, and after that, it’s $5.99 a month. Homeowners of earlier Oura rings received a free lifetime subscription in the event that they purchased the Gen 3 earlier than November twenty ninth, 2021, however that choice is now not obtainable. Additionally, Oura says on its FAQ page that in the event you cancel or select to not subscribe, you’ll nonetheless be capable of see your readiness, sleep, and exercise scores.

Oura’s trying far off into the way forward for wearables, and it’s relying on its prospects to really feel just like the wait is value it

Whether or not the Oura Ring is value the fee boils down as to whether you’re able to commit. Whoop is cheaper within the brief time period, particularly for the reason that firm lately lowered its subscription costs. Nonetheless, it tends to tip in Oura’s favor in the event you’re prepared to stay with this platform for greater than two years. (Except you got the Gucci model or plan to purchase your ring secondhand.) A less expensive Fitbit may even get you wonderful sleep monitoring and restoration metrics, on high of different sensible options like notifications and contactless funds. That mentioned, Fitbit’s fortunes haven’t appeared too nice as of late.

So is the Oura Ring value it? If restoration is essential to you however you favor analog watches or don’t discover wrist-based trackers snug, then I’d say sure. Not like the failed Motiv Ring, it’s not trying to do too much. It’s attempting to be a wonderful well being tracker, and on that entrance, few others do it higher.
