Oura Ring 4 Ultimate Scientific Review

if you're considering getting the new Aura ring 4 you're likely to fall into one of two categories one you're a new user and you're checking out different smart rings and SmartWatches or two you

already own an ordering three and you're looking to upgrade today we will therefore scientifically answer two questions one is the ordering for a good health and Sports Tracker in general and

two should you upgrade if you already own the ordering 3 we will do this by systematically testing the new ordering 4 using different reference device and by comparing these results to dozens

of other smart rings and SmartWatches now before checking those results let's first briefly discuss what is different about the aing 4 compared to the aing 3 honestly the differences aren't huge the

only difference I really care about is the new smart sensing technology Aura says that the generation 4 ring automatically adapts to the user's unique physiology according to Aura this

technology ensures continuous and accurate data collection by finding the best signal path even if the ring shifts on your finger if this is true this would make the ring quite a bit better than Generation 3 since before I always

tried to make sure that the sensors were correctly aligned to the bottom of my finger but it would often still shift around even with the new generation 4 ring I still tried to align it correctly because it probably still helps with

performance however this is actually quite frustrating with the a ring 4 with a generation 3 right here I could select a model that had a flat top so that made it really easy to align the generation 4

ring however is perfectly round and only has a small indentation on the bottom which I find frustratingly hard to feel now the design of the aing 4 has also changed on the inside with a fully round

interior shape and recess sensors aiming to enhance your comfort when you're wearing it it's actually still not perfectly flush on the inside yes it's definitely less noticeable than with the Generation 3 ring but honestly I don't

really care either way but I'm also not very sensitive to these things I'd be curious to hear if others have experien with this so feel free to share your feelings in the comments below now the improved sens technology also increases

the battery life with the oring 4 now lasting up to 8 Days on a single charge but this is honestly a small difference from the 7 Days of the oring 3 one thing to keep in mind with smart Rings

compared to smart watches is that the size is fixed so make sure you get the right size the whole process is very similar to previous aing models you get a free sizing kit which has plastic

versions of each of the sizes I would recommend trying the final size for at least a full day and night and make sure you're trying it under different conditions I found that during certain sports or when sleeping in a warmer room

my fingers get swollen just a little bit and a size I thought was right initially wasn't very comfortable in the end but to summarize the main difference between the oring 4 and oring 3 is the new smart

sensing technology which supposedly improves the tracking performance of the oring 4 so let's see if this is actually true let's start looking at something relatively easy tracking hard rate and heart rate variability at night the way

we'll be testing the performance of the oring 4 is by comparing it to an EC G reference now for four nights I slept with both an ECG chest strap that can accurately measure the distance between his heartbeat and I compare that to the

measurements of the oring for you can see that I at least slept close to8 hours for this first night with the measurements of the oring in red being very close to the measurements of the reference device in blue green so that's

looking very good for this first three quarters of the night or so I had a relatively high heart rate then it dropped for the last quar of the night and both devices measur more or less the same heart rate so that's looking very

good only this peak right here doesn't match between the reference device and the oing if I remember correctly I actually got out of bed and the oing didn't fully measure that increased heart rate but it could actually be that the algorithm of the or ring ignores

anything for when you're out of bed so in that case it would still be correct and for all the other nights we see more or less the same thing so here again the a ring in red follows along very well with the reference device in blue green

here again I went out of bed and the reference device deected a higher heart than the aura ring but again I think the aura ring might int remove those measurements so it only measures the heart rate when you're still in bed and

to close off for this third night and also this fourth night we again see the same thing the aura ring agrees very well with the reference ofice only some really high increases in heart rate

aren't detected by the AA ring but these are most likely moments that I went out of bed to go to the toilet we can actually make an overview of all these results and that's what's displayed right here each dot in this plot is a matching measurement between the aura

ring on the left and the ECG chest strap on the bottom and the black line shows where where the point should be if there's perfect agreement and the blue line shows the best fitting line through all the points and as you can see the

blue line and the black line overall agree very well and there's only a few points away from the black line and if they are away from the black line they're mostly below it but there's actually only a few points right here

below the black line and in these cases that means that the polar h10 ECG chest St detected a higher heart rate than the aing so these points right here are most likely the moments I went out of B and my heart rate increased and I really

think the oring is just not designed to detect these but it only detects your heart rate when you're actually in bed in general I think this shows that the a ring is very capable of measuring your heart rate throughout the night however

what about heart rate variability or HRV can the aing measure this at night well that's displayed right here for the first night again we have the aura ring in red and the reference in blue green HRV is actually harder to measure

because instead of just measuring the total number of heartbeats the a ring needs to measure the exact distance between each of the individual heartbeats now HRV is a measurement that is generally better if it's higher so we want those values to be as high as

possible though this is very individual so you want it to be as high as possible but as high as possible for you for this first night the aura ring and the reference device agreed very well during the first part of the night they had a

relatively low HRV and at the end had an increased HRV so was likely more relaxed here and at the end of the night though it could also be had for instance a late meal so my body was still digesting this it took a really long time for my heart

to actually drop and my heart variability to increase but regardless both the aura ring and the reference device were able to pick up on this also for this second night we see a very good agreement between the reference device

and the aura ring that's also we see for the third night and also the fourth night so overall also for HRV we seem to see a very good agreement between the aura ring and the reference device but again let's make an overview plot for

this so this is a similar overview as before but now for HRV instead of heart rate and in general there's just a very good agreement between the polar h10 ECG chest trp along the horizontal axis and

the oring along the vertical axis yes there is some deviation mostly here in the higher HRV range so in the lower HRV range right here almost all points are very close to the black line but in the

higher HRV range there's a bit more deviation and this would be good enough for me to get a general impression of my HRV values throughout the night the heart rate and HRV tracking of the oring 4 actually looks quite good but is the

oring 4 worth an upgrade compared to oring 3 well the quality of the actual heart rate and hvv measurements was already very good with oring 3 so if there is an improvement there it's

relatively minor however there is potentially one difference the main Improvement appears to be that there's less missing data now I'm relying on quite old test results for the oring 3 so I'll take updated measurements over

the next few weeks but let's take a look at those results so these are the results for the aing 3 they are from quite a while ago so from the end of 2021 so 3 years ago by now so I'm not sure if the algorithm actually changed

in that time but what you can see is that there seem to be more missing values for the oring so there's some missing values right here for this Knight also this Knight right here had a big missing section in this area right

here this Knight looks a bit better but again some missing data here and also this fourth night as an example had a lot of missing heart rate data so the ordering three at least based on these examples appears to have more missing

data than ordering four but I would like to test both again at the same time with the same firmware or at least the most upto-date firmware for both but let's now take a quick look at HRV so here we have again the ordering three but now

measuring HRV and you can see that there's indeed more missing measurements in Red so we see a big gap right here but in general because the lines are not connected that means each time there was a missing value right there also for

this KN right here a lot of missing HRV data here in the middle this KN looks a bit better with only minor missing values this night right here is a little bit newer but still from 2022 so quite

old so as I said I'll retest the aing 3 somewhere in the next few weeks or months I need to make a second account and I probably need to pay for that but after I'm able to do that I'll show out those results as well but this match with what Ora claims is that there will

be less missing data with the oring generation 4 compared to the oring Generation 3 this to me indicates a potential relatively small Improvement of the aing 4 over the oring 3 though it

is technically still probably significantly better the question is if this Improvement would actually lead to any real world differences to anyone using the a ring and honestly I doubt it I would be happy enough with my

generation 3 ring and basically most scenarios though given the choice of course I would still pick the generation 4 over the Generation 3 but let's now make things a lot more difficult and let's take a look at the heart rate

tracking performance of the a ring for during exercise now as we've seen in previous testing the form factor over a ring doesn't appear to be ideal for heart rate tracking during Sports I'm not sure if the signal is more noisy the

blood flow in the fingers is harder to measure or if companies just don't have enough experience with this technology yet regardless I haven't used any smarter ring yet to contract my heart rate accurately during exercise with the

Aura app you can track five different types of exercises outdoor running in door running outdoor cycling indoor cycling and walking so let's see if the a ring for is the exception to the rule and if it performs better than all of

the other Rings I've tested in the past and we will start by looking at what is typically at least one of the easiest exercises to track indoor cycling but this overview actually doesn't look very

promising for the aing 4 now this plot is an overview of the 18 indoor cycling sessions I did where I compared the a ring against an e chest STP which is a reference from Polar and that reference

is along the horizontal axis right here which can generally record my heart rate very accurately and on the vertical axis right here is the ordering for that means this the measurements would perfectly agree all points should be on

this blue line right here but as you can see this doesn't look great yes there is quite a density of points right here close to the blue line but there's quite a few points here below the Blue Line

especially in the higher heart rate range right here this isn't typically what you see from many other devices out there the correlation which is this R

value up here is also quite low at 0.5 now the best correlation is 1.0 and 0.5 is really among the lowest correlations I've seen for any devices out there but

we now really need to take a look at the individual spinning sessions to see why and how the oring for is actually struggling here we have the first example interval spinning session where we see exactly what the issue is along

the horizontal axis we have the clock time and my heart rate is along the vertical axis with in blue green my heart rate according to the polar h10 ECG chest strap and then read my heart rate according to the AA ring 4 so it

seems that for the beginning of the spinning session the AA ring four struggled quite a bit detecting a way too high heart rate right here then just going all over the place until about the

middle of the ride after which it picked up quite accurately on my heart rate so it could be that my fingers were warming up through this time and then here it actually caught onto my heart rate but this just isn't very good this second

spinning session actually looks quite a bit better quite a few of the peaks in my heart rate were detected a lot of the dips weren't correctly detected but this looks quite okayish this third session

is again quite horrible only here near the end did it do okay at best also right here for this fourth example only near the end was it able to catch on somewhat to my heart rate in the

beginning it did really horribly also right here didn't do very well that's more or less the general story and at the end of the ride sometimes it does quite okay but in the beginning it generally tends to struggle my thinking

is that potentially at least after working out for a bit the blood flow to my fingers gets better and better and at some point it can pick up on somewhat of a signal but still this doesn't look that great to put these results into

context we can compare them as many of the other devices I tested in the past you can see that in this overiew right here along the horizontal axis is the correlation value we're looking at before we want that value to be as close

to one as possible and on the vertical axis I order to watches from worst to best so the further to the right and the higher devices the better is its correlation with the reference device

and the order ring four is marked in red right here now as you can see it's really towards the bottom left so one of the worst devices out there when it comes to heart rate tracking during

indoor cycling it's actually very close to the a ring 3 right here now I only took data from the a ring 3 from the months before I tested the a ring 4 so very recent data and as you can see

there isn't the big difference between the or ring 3 and the or ring 4 I suspect they perform more or less the same and this is random variation and both of them are honestly doing terribly so I cannot recommend the order ring

three or four for tracking your heart rate while indoor cycling as you can see there's many better devices out there so let's take a quick look at some of the top performers and of course it was difficult to read those labels so here

I've zoomed into just the watches with a correlation of 0.9 or higher and as you can see the best devices out there tend to be apple watches also the pixel watch

3 is doing very well different Huawei devices so the strap also has good health tracking similar to the aura ring but in addition is also quite decent into tracking your heart rate during exercise so for some people that might

be a good alternative to the oring if you really care about sports trkking next let's take a look at another exercise which is sometimes hard and sometimes easy to track for different devices indoor running in total I did

three indoor runs with oring for by the way if you want to get early access to results and want to support the channel I now started the YouTube memberships which you can find in the link up here or down in the description below I'm

struggling a bit making these videos next to my day job and having an editor really helps but it's financially an extra burden so if you want to help me keep making these videos please consider becoming a member which also includes a

private Discord server but back to the testing here we have a similar over before but now for indoor running and honestly this doesn't look that terrible there are quite a few points close to the blue line now here in the lower

heart rate range there are quite a few points above the blue line so still some deviation but compared to what we saw for indoor cycling this looks a lot better the correlation is also quite a bit higher now at 0.96 though that

correlation is a little bit deceptive now because all the points here are above the Blue Line making the correlation artificially a little bit higher because it can still fit a quite good linear line through the points a little bit higher here in the lower

range but let's take a look at the runs themselves see if we can explain this deviation right here so here we have the first indoor run that I did where we see that the aing in red somewhat followed along with the reference in blue green

it's not even that great honestly because quite often detected it to low heart rate but this might be good enough this second run actually looks a lot better here did quite well it was

generally able to follow along with my heart rate and also this third session was okayish but again a too low heart rate was often detected so I was actually running a bit faster during this workout than this workout so

potentially here the Cadence and heart rate were similar enough that the oring 4 got confused and for this session they were different enough that it didn't mess up as much so generally better than what we saw for indoor cycling but still

not very good but we can again put these results into perspective by comparing these against many of the other devices we tested in the past here we have a similar over to before but now for indoor running there's not that many devices in here because I only recently

started testing these devices during indoor running so there's only very few watches actually tested for this but as you can see the a ring 4 even though it didn't do as bad compared to the other exercise it's still not doing great

there's many better devices out there it does seem to be potentially a little bit better than the a ring 3 which is the worst device out there but generally I still don't know if the a ring 4 is actually good enough for tracking your

hard hood while indoor running it's really on the edge so for indoor running the results aren't horrible it's basically the best I've seen up until this point for the aing for different exercises but the results are still not

good so far nothing is really convincing me that you can use the AA ring four or three for that matter to track your heart rate during exercise as I mentioned before you can only use the aura ring for five different types of

exercises and one of them is outdoor running so let's see how it did for that and I do need to mention I tested the a ring when it was rather cold outside sometimes I wear gloves but sometimes I don't so it might be influenced by that

because there's just less blood flow to the fingers but let's take a look here we have that overview but now for running outside and as you can see this looks okayish at best so definitely looks better than what we saw for

cycling indoors but not as good as we saw for running indoors yes most points are close to the blue line at least but there's quite some deviation for instance right here but also here above

the blue line and even here below it there's still quite some deviation the correlation is also not amazing at 0.7 9 honestly not that great but let's take a look at the individual runs to see how

big these deviations actually are so let's quickly look again at some example runs right here you can see that the oring in red wasn't able to detect many of the peaks in my heart so I did many different intervals and it just couldn't

keep up this second run looks a bit better here near the end but it struggled in the beginning this run again doesn't look very good many of the peaks in my heart rate are missed this run maybe looks okay I don't know what

you think this looks again a bit better and here also bit better of results so definitely not horrible but it could be a lot better many devices do a lot better so let's take a look at that

overview with the other devices and again you're familiar with this type of overview by now but now it's for outside running and we want the devices to be as far to the top right as possible and as

you can see the aura ring 4 in red right here really isn't doing that well it's again amongst the poorer performance out there and it's really close to or ring 3 as well so probably both of them are

doing about the same and there are many better devices out there again Apple watches are quite good also my initial testing of the coral Space 3 did quite well but also the pixel watch is very

good here we have the pixel Watch 2 I didn't include the pixel watch 3 but this actually did even better than the pixel Watch 2 so the whoop strap 4. that

really outperforms the AA ring and I mentioned the Roop strap since this is a direct competitor to the AA ring but again the best devices out there are different Apple devices the pixel watch 3 and some of these other high devices right here that was actually better than

I expected originally the results aren't that that much worse compared to running inside still though the overall patterns generally match between the aura ring and the reference device there are enough deviations for me not to trust

the results too much running indoor and outdoor does appear to be easier than indoor cycling for the or ring to track I suspect this is Du to me holding on to the handlebars and that introduces some kind of noise to the signal compared to

my hands being completely free while running now one thing the oring three has been quite bad at Rec cycling outside so let's see if the oring 4 can do any better I wanted to record some

nice Aura ring b-roll and of course this [Music]

happened BR yes I'm not the smartest sometimes but let's take a look at the actual test results for cycling outside and those are displayed in this oview right here

and this is based on a total of 37 bike rides and we actually see pretty poor agreement between the reference device and the ordering for yes there are some points here close to the blue line but

this big cloud of points right here is actually deviating quite a bit from the Blue Line this really doesn't look that good it appears that quite often the a ring just keeps detecting the same heart

rate around 120 BPM no matter what my heart rate was in reality so if you look for instance right here where in reality my heart rate was 150 bpm there's quite a few moments when the a ring still

detected about 120 BPM the correlation is also quite low now at 0.5 again similar to what we saw for cycling indoors but honestly this looks even a bit worse but let's take a look at this

individual bike rides to see how bad this actually is here we have the first bike ride I wanted to share with you and you can see quite clearly that the aing in red keeps detecting a heart rate

around 120 BPM no matter what happens we see the same thing more or less for this bike right though a little bit of a lower heart rate here in the end and it seems to be biased to detecting 120 BPM

also right here at least varying between 135 is and 100 BPM also right here again around 120 BPM and so on this just doesn't look very good this bike ride is

actually a little bit better here near the end maybe but overall this really doesn't look very good I'm not sure what's going on here I don't know how Ora thinks they actually measured my heart rate here this just isn't good but

again let's put these results into perspective and as we've come to expect in this overview the or ring 4 really isn't doing well for outside cycling it's really close again to the oring

ring three right here and both of them have a correlation between 0.4 and 0.5 so not very good also the Galaxy Ring did about the same as these two rings right here so a ring as a form factor

that doesn't appear to be that good for heart rate tracking especially during outside cycling but let's zoom in again to look at some of the better performing watches so right here we have just the devices with a correlation of 0.8 or

higher again the whoop strap is pretty good not amongst the absolute top performers but maybe good enough for many of you and as we've come to expect watches are really good also the pixel

watch 3 and also some Huawei devices so it really depends on how important outside cycling is for you and in general as always if you want the most accurate heart rate tracking during any type of exercise an ECG chest trp is

generally the best option so that looks really bad for me this isn't good enough in terms of heart rate tracking I don't know what you think it's probably because I have to hold on to the handlebars quite tightly when cycling out side and this appears to deal the

death blow in terms of heart rate tracking performance for the oring 4 most of the time it just keep keeps detecting a relatively stable heart rate even when in reality my heart rate is steeply increasing or decreasing it's

better than random but not by much so overall not looking very good for the oring 4 in terms of sports tracking it honestly doesn't appear to do any better than the oring 3 but let's take a look

at all these results at once by the way quick side note all right it's another day another bike the other one is still broken but I wanted to say one more thing about the oring by now there's also an option for other sports in the

app I don't know what could actually be tracked accurately I actually ask Ora and if I get an answer he will be Rob now explaining that hi Rob from the future here so I was recording some B-

roll and I actually now clicked on this option of other workout if you click on other exercise you can basically select from many many exercises now you can see some of them right here so it's no

longer just those five exercises but you have many options still those five are showing as the first ones but it appears that Ora did make it a priority to give you that option to do other exercises still I don't think that would improve

the heart rate tracking performance but back to pass drop and here we have that overview of all results for heart rate tracking at once where we have the different sports along the horizontal axis right here so from spinning to

biking to indoor running and outdoor running and the correlation value we're looking at before is now along the vertical axis right here where each dot is a single device for a single exercise

and I've marked the a ring four always with a red line and a red dot and as you can see the aing is always amongst the lower devices out there now you also see two numbers the first is that

correlation value and the second is a percentile that percentage basically indicates how many devices are worse than the order ring 4 so for instance this 4% means that 4% of the devices did

worse than the order ring 4 for spinning and 96% did better or right here for biking 18% did worse that means that 82% did better now for running indoors we

saw before it didn't do as terrible so 36% of devices do worse than the ordering for but it also means that 64% did better and again also for running outside it really isn't very good only

14% of devices did worse which means that 86% did better so overall really not looking good for the aura ring when it comes to heart rate tracking while doing exercise and we can actually

compare this to the oring 3 as well so here we have those same results but now for the aing 3 and as you can see this generally looks very similar to what we saw for the oring 4 it only did quite a bit worse for running indoors but

otherwise the aing is really amongst the worst devices out there both the a ring 3 and the aing 4 I cannot really recommend either of them all of these results combined seem to indicate that the a ring for can track your sleep but

it's less suitable for tracking your exercise but what about sleep stages like deep sleep light sleep and R sleep can the aing for track those let's have a look at those results but first if you're finding these videos interesting

it really helps me get access to new devices sooner and helps me reach more people if you like this video And subscribe to the channel pressing those buttons really makes a huge difference and of course commenting also helps if you have a moment I would really

appreciate it but back to the testing here is an overview of the Sleep stage test results for a total of six nights to test the Sleep stage tracking performance I compared the order ring 4

against the zMAX EG headband which can actually measure my brain waves now this device also has its limitations especially when it comes to detecting awake time but it will give us a general impression of the Sleep stage tracking

performance of the oring 4 now on top are the sleep stages as recorded by the zMAX EG device and on the left are the sleep stages as recorded by the oring 4

now each column right here sums to 100% meaning that we can see what percentage of each sleep stages according to the zMAX was predicted as each sleep stage by the oring 4 and if they perfectly

agree all values on the diagonal right here should be 100% now first of all we see that about 70% of what was deep sleep according to the EG device was also deep sleep according to the a ring

so that's pretty good actually and if there was any confusion this was mostly with light sleep at about 25% light sleep agreement is actually very good at about 80% and most

confusion in this case was with deep sleep Ram sleep agreement actually seems somewhat less good at about 57% it's not actually as bad as this indicates but still looking pretty good and most

confusion in this case was with light sleep but also with awake time sometimes now as I said I won't be focusing on a wake time but just for completeness about 41% of what was a wake time

according to the EG device was also a wake time according to the oring 4 but let's take a look at the individual Knights now to better understand what's going on here and indeed looking at the individual kns will help us understand it even better and here you see the

first night I wanted to share with you on top we have the sleep stages according to the zMAX EEG headband with along the horizontal axis here the clock time and my sleep stages on the vertical axis and on the bottom we have a similar

plot but now for the a ring form and I actually made a mistake before in that overview we're not looking at six nights total but 11 nights total and this was the first one I wanted to show you and in purple now right here I highlighted

the deep sleep as recorded by the EG device and as you can see this generally matches very well with the Deep Sleep measured by the oring 4 it's not perfect but most of the Deep Sleep detected by

the EG device is also detected by the oring 4 that's also what we see for this night right here so I had three main deep sleep segments and these were also detected by the oring though it did detect some extra deep sleep right here

and also in the beginning of these two segments and also for this third third night it honestly looks pretty good for the aing in terms of deep sleep and we can do something similar but now for R sleep which is marked in red right here

and as you can see I likely had one two three four main Ram sleep segments and three out of four of these were also detected by the aura ring one was missed right here and the or ring detected some

extra awake time right here but overall this doesn't look too bad we can see something similar for this other KN I wanted to share with you but in this case when I had some REM sleep here at the end of the night the or ring mostly

detected awake time so I had really Sleep Quality this night and for this third and final example we again see that most R sleep actually agrees very well between the EG device and the ordering this short ram sleep segment

here was missed and also here in near the end there's some disagreement but overall this doesn't look too bad I just also had poor Sleep Quality for many of the KN that tested the a ring and we can actually directly compare the a ring

four here on the left to the a ring three here on the right and as you can see their performance wasn't that different they did best at detecting light sleep deep sleep was also pretty

okay for both of them and RAM sleep seems to be the hardest and again we won't be focusing on the Wake time here because the EEG device detects a lot of extra awake moments that weren't really awake moments so overall this seems to

me to indicate that the oring 3 uses the same algorithm and has similar performance as the a ring 4 I should also mention I didn't test them for the exact same night so I basically tested

the a ring 3 up until the point I got the oring 4 and I only took recent nights for the oring 3 so there will be some variation from night to night but let's now compare the performance of the

oring 4 to many more devices besides just the oring 3 this graph right here shows you an overview of the agreement of different smart watches and smart rings with different reference devices along the horizontal axis we have the

average agreement over the individual sleep stages and on the vertical axis we have the agreement of the worst sleep stage and the better the agreement the more to the top right the devices now I have to mention this overview is

slightly complicated because I use different reference devices the devices not marked in any color were tested against the dream 2 EG headband but I cannot use it at the moment the devices marked in blue purple were tested

against polography which is the gold standard in sleep stage tracking and the devices marked in green were tested against the zMAX EG headband the one we used in this video so the better the agreement the more to the top right the

devices and you can see the results for the ordering 4 right here so it appears to be among some of the better devices but not the absolute best devices and it actually appears to do slightly worse

potentially than my previous testing of the aing 3 so the results right here for the aing 3 are not the results we're just looking at so recent testing but results from maybe a year or two ago so there appears to be some difference

there but I have to mention one thing here I recently noticed that my reference device is showing more and more issues and that's probably why we see for instance that the pixel watch 3 is doing slightly worse than the pixel

Watch 2 but also for instance the h p 4 is doing slightly worse than the Pod 3 and as you will see in an upcoming video the Apple Watch series 10 is also a bit lower in this graph than for instance

the Apple watch 9 8 and 7 though don't worry it isn't bad at all but I think in part this is because my reference device isn't performing as well as I'd hoped so I'm actually switching to a different

unit of the same device now hoping that I can solve that problem because many of the devices I tested recently just do slightly worse than I expected even though I mostly know that they use the same algorithm as a previous device so

they should be performing more or less the same now of course we expect some random variation but the fact that for instance the pixel watch 3 is worse in the pixel Watch 2 the or ring 4 P to do slightly worse than the or ring 3 the h

b 4 slightly worse in the h b 3 and so on this does indicate I need to solve something because I also need to exclude many more knights from the reference device just because something was wrong with that particular Knight so hopefully

switching devices will solve that but for now what I want to say is I don't think that the order ring 4 is actually doing worse than the a ring 3 as we also just saw in the comparison we were doing so in reality we might just need to bump

it up a few percentage points but still overall this confirms what we know about about the or ring it's a pretty good sleep stage tracker it doesn't do quite as well on me as for instance the Apple

watch the Sleep 2 or Nua app and also the eight sleep podt but it's still amongst the top trackers out there and I would say it's amongst those top four so Apple watch sleep 2 eight sleep and Aura

are my top performers and in the second tier of devices are for instance the whoop strap but also different Fitbit devices so those are the only ones I would really recommend people use so fibit devices also include different

pixel watches because Google owns Fitbit so overall this indicates to me Aura is still a very solid sleep stage tracker but about the same as the aura ring 3 so if you care about sleep staging it's probably not worth upgrading from the

three to the four and if you also want Sports tracking them for instance the whoop strap or a pixel watch or an Apple Watch are probably better Alternatives now similar to the aura ring the whoop strap has a very good app and ecosystem

so out of the three Alternatives I mentioned that's probably the one with the best app but the pixel watch and also the Apple watch probably have slightly better heart rate tracking especially and the Apple watch for sure also better sleep stage tracking the

pixel watch is actually comparable to the whoop strap so it really depends where your focus is if you purely want Health tracking and sleep stage tracking the aura ring is amazing but if you also want Sports tracking look at some of

these Alternatives so the Sleep stage tracking of the oring 4 is actually pretty good as I've come to expect from Aura based on the data I have I suspect it basically does the same as the oring 3 and this makes sense as before when

Ora updated the algorithms they got in touch with me and also made announcements publicly it's actually quite an investment to update your sleep stage tracking algorithms since this usually involves collecting a lot of new data with both the aura ring and a

reference PSG measurement on a lot of people which is really expensive but let's get back to the two questions we asked in the beginning one is the ordering for a good health and Sports

Tracker in general and two should you upgrade if you already own an aing 3 while regarding the first question yes the aing for is great at Health tracking but it's not so good at sports and

exercise tracking at least not based on my data if you're just interested in tracking your sleep and General Health the oring is one of my top recommendations Aura also provides a great app that helps you interpret data

which is very important and it's also relatively comfortable to wear on your finger for me those are the main selling points of the aing in general especially given that interpreting your sleep and health data can be quite hard and or has

figured out a way to present this to you really well within the app it's useful for anyone with different levels of experience with sleep and health tracking if you just want basic insights or dive a bit deeper you can do both if

you also want to track your sports and exercises the aing just isn't up to the task at least not based on my testing as I've mentioned in other videos my preferred all round device is the whoop strap since this has both good health

tracking and good sports tracking the Sleep stage tracking of the whoop strap appears to be slightly worse than the oring sleep tracking but it's still very usable and better than much of the competition out there now let's address

the second question should you upgrade from the oring 3 to the oring 4 well probably not if your oring 3 still has a good battery I don't see many reasons to

upgrade I can imagine that aura at some point only releases some of the new features to the oring 4 which does mean that the oring four is more future prooof so if I had to choose at the moment and I didn't own an oring yet I

would definitely get the four over the three but if you already own the Generation 3 I would just save your money at least for now you can always upgrade the moment that aura does decide to release some features to just the

generation 4 the overall performance of The Generation 4 ring doesn't appear to be much better than the Generation 3 the main thing that will be better is that you will likely have less missing data during the nighttime measurements so if

that's something that you're prone to that will be the main reason I would consider upgrading and then it might be worth it if you do decide to get an oring three or an oring 4 I have an affiliate Link in the description below if you want to support a channel however

I cannot offer any discount on that affiliate link and you might be able to find a friend referral link online that does provide a discount so I'd recommend searching for those first if you cannot find one using my link would be greatly

appreciated but again if you own the generation three already don't just upgrade because the four is the latest and greatest it's honestly not that different if instead you find sports tracking important and you decide to get

a whoop strap you still want an aura ring an hle pod 4 another device or anything at all on Amazon for that matter even something a small as toilet paper want to support the channel and save some money there are different
