so really by now we all know which the best smartwatch is on the market in 2021
the main ones being the galaxy watch 3 and the apple watch series 6. but how accurate
are they when it comes down to heart rate tracking well in this video i'm going to
test just that stay tuned and don't forget to leave a like if you found the video helpful
guys welcome back to tech it easy so today i finally decided to test the accuracy of
probably two of the best smart watches going into 2021 the apple watch series 6 and of course
the galaxy watch 3. now of course to do this i'm going to need some sort of professional monitoring
equipment so the guys at well you reached out to me and asked can i review their o2 ring and
i thought that'd be a really good opportunity to test the accuracy of smart watches and fitness
trackers io so here it is this little guy right here is the o2 ring now this continuously tracks
your heart rate and your spo2 primarily it's actually for sleep tracking it has a really
cool feature where when it detects your spo2 levels drop it'll actually vibrate to make you
turn over in your sleep without waking you up so if you snore get one of these but aside from that
it's actually incredibly accurate when it comes to heart rate tracking and once paired with the app
it gives you a really detailed analysis of your heart rate and spo2 so that's what we're gonna
use as a baseline to test the galaxy watch 3 and the apple watch series 6 on their accuracy now if
you enjoyed this video i'll do a follow-up episode testing some of the most recent fitness trackers
as well so big thank you to welu for sending this out to me and let's get on with the testing so to
get started i'm going to go ahead and install the vhealth app for the o2 ring and then i'm going to
get back to you okay so i have just started the test for the galaxy watch 3 heart rate tracking
and it is way off so i'm just going to break away and see if i can get it a little bit tighter and
adjust the o2 ring and my galaxy watch 3 and see what happens okay so we are back and things are
looking a little bit more promising now the heart rate readings do seem to be accurate against the
o2 ring but what you will notice and something that i'm finding a little bit annoying is that the
galaxy watch 3 is super slow the continuous heart rate monitoring doesn't actually seem to be that
continuous it seems to lag behind the o2 ring by quite a lot it does then catch up to what the o2
ring was displaying and then occasionally it will just stay in place for a good couple of seconds
now i made sure i did quite a few tests and kept adjusting the o2 ring and the galaxy watch 3.
and i have to say i don't have any issues with the actual accuracy of the galaxy watch 3.
it is hitting the same heart rate that the o2 ring is displaying but again there's just that annoying
lag so what do these results mean for those of you who want to keep an eye on their heart rate
well the galaxy watch 3 is by no means inaccurate many a time it did show the exact same heart rate
as the ot ring did which was great but what it is lacking is the details it doesn't have that
consistency and the continuous heart rate tracking as i mentioned earlier is not quite up to scratch
it does seem to be a little bit slow and it doesn't update nearly as much as say
the o2 ring does or a similar device so again what you're going to be missing out on is the
details in general though the galaxy watch 3 heart rate tracking is going to be absolutely fine and
more than adequate for most people but if you're looking for sort of medical grade tracking then
maybe the galaxy watch 3 isn't the best choice for you yet now let's move on to the apple watch
series 6 and see how that does and see if we notice any of the same problems in that as
we did with the galaxy watch three okay so i've switched over to the apple watch series six now
and i'm gonna do the same as i did with the galaxy watch three i'm just gonna leave the continuous
heart rate tracking gone on both the apple watch series six and the o2 ring and see how they do
now straight off the bat they were actually almost banged on each other they were extremely close
but what i'm noticing is the same problems we had with the galaxy watch 3 in that the apple
watch series 6 seems to be lagging behind slightly as time went on with the first test it seemed to
get further and further out so i did a little bit more adjusting and then the results started
to be a little bit more consistent although like the galaxy watch 3 the apple watch series
6 continuous heart rate tracking is a little bit slow it does appear to be faster than the galaxy
watch 3. i'm also seeing the same heart rate readout on both the o2 inc and apple watch
series 6 at the same time more frequently so you know me i am on team samsung but i would have to
give the point to apple here the apple watch series 6 does seem to be a lot more consistent
than the galaxy watch 3 and is proving to be a much more reliable heart rate tracker
now as well as testing the heart rate tracking i thought it'd be a pretty good idea to test out the
spo2 monitoring too so in a similar fashion i'm going to test both the apple watch series 6 and
the galaxy watch 3 out except this time there is no continuous measuring so i will have to set them
off manually and what i'm noticing here with the galaxy watch 3 is that it's only 1 out each time
which for me is a good margin for error i did the test about three to four times in total and each
time it came out one percent out now interestingly once we get to the apple watch series six same
tests the rings in the same place it came out dead on each time each time i tested it it was almost
exactly the same apart from one occasion where it did read it as one percent higher for me though
i really wouldn't want to say that the apple watch series six is better for spo2 monitoring
since it is only a one percent difference but i can't ignore the test results the apple watch
did get it right two out of three times and the galaxy watch was always one percent out
so thanks to the guys at well you we've now tested the accuracy of the apple watch series 6 and the
galaxy watch 3. and the results were interesting i have to say let me know your thoughts in the
comments section and if you do want to step up your tracking game maybe consider getting
one of these they're currently going for around 150 pounds on amazon or around 180
let me know what you think in the comment section as always and if
