hi everyone welcome back to wes knows tech news and reviews today we'll be talking about heart
rate accuracy of the gt-r2 as well as the gts2 mini now i know what you're thinking these two
watches are in slightly different price ranges as well as just different markets all together so on
one side the amazon gts2 mini is a superb budget smartwatch on the other side the gtr2 that we
have right here is actually the premium range or the top of the range of the amasfit smartwatches
now i've actually decided to compare these two and compare the heart rate accuracy
for physical workouts because i've been doing comparisons and tests and we can see how amazing
these two smart watches from a mass fit have shown themselves in regards to accuracy of the heart
rate sensors on the back of the watches for runs for circuit workouts but we know that there is a
problem and that a lot of the smartwatches brands like fitbit polar garmin they're not amazing
at actually registering heart rate from physical workouts at the gym for example if you're new to
westnow's tech news and reviews we talk about the latest tech news we do brutally honest reviews and
share hacks and tricks along the way so what i've done is i've put these two watches on so
on my left and on my right wrists and i had the polar h10 ecg chest strap on me while i was doing
a bit of physical exercise like doing a bit of weight lifting etc so let's have a look at
the plots from the polar h10 and on top of that plot we're going to be putting the massive gtr 2
heart rate plot and then the amazon gts2 mini and i can tell you as a teaser the results
were not amazing but at the end of the day it's a fair comparison and test
so let's get into it and let's take a look what we came up with but just before we actually get
into the details before we look at the plots let's have a quick intro of the contenders so as we're
going to start with the amazfit gto2 it's only logical that i tell you all about it two minutes
so basically this is the top of the range this is the top of the mass fed smartwatch range yes of
course there is a gts2 which is a more rectangular in shape watch but this is round it's 1.39 inch
large it's got a great resolution of 454 by 454 pixels giving us 326 ppi so that is a very sharp
screen and most importantly the cpu is great it's quick the user interface is just a pleasure to use
if you've been watching the channel you know that i've actually switched over from the honor magic
watch too which is an amazing watch to the gtr2 as my day-to-day watch why well it's amazing it's
very functional it's got 90 sport modes it's got internal inbuilt gps it's got a stress monitor
in fact the stress monitor can do you continuous tracking throughout the day on top of that you've
got your spo2 monitor yep it's on demand so it does your blood oxygen saturation level monitoring
on demand but still it's there you've got all the usual notification management tools but on
top of that that extra mile is the fact that you can't download up to 3 gb of music to the watch
on top of that there are offline voice commands so there's a microphone and what you can do you can
actually speak into it and the watch will follow your commands for example you want to go outside
for a jog later in the evening it's cold you don't want to take your glove off you don't want to
fiddle around with the watch too easy you just sell the watch open work out say which workout
you want to do and get into it start running you want to play music tell it to start playing music
there's a lot of functionality with the voice commands and of course we do know that alexa is
coming via an ota update and it's not that far away because literally two weeks ago we did get
the ota update which actually allows the gts2 mini the most budget smartwatch in the amasfit range
to actually have alexa on top of it and that's a very cool addition so if it's there it's going to
hit gtr 2 quite soon as well anyway now that i've told you so much about the gto2 let's
actually get into the plot so what i have there is the plot from the polar h10 ecg chest strap
and on top of that we've got the plot from the optical heart rate sensor on the back of the gtr2
so let's take a look at the results now looking at the two plots i can see just a shocking
shocking difference the average heart rate measured by the polar h-10 ecg chess strap was 139
beats per minute the max was 163. the gtr 2 has actually measured the average heart rate at 107
beats per minute while the max was just 136 but that's what we get usually when we do have
physical activities and again we've just started doing these comparisons with their mass fit but
as we go through the other brands you will see a very similar situation anyway so if
we'll have a look at the variance in terms of percentage so for the average we're out by 23
with the max heart rate we're out by 16 and a half percent that's quite a bit and we can see
that is basically along the whole time we're working out so from start to finish in most of
the cases the heart rate was just under estimated yep you can see the rises so you can see some of
the peaks being traced through you can see the throws but they're still way way under the polar
h10 plot we do see a bit of convergence of the two plots coming to the end of the workout but
still it's just wow it's off by quite a bit before we get into the results of the gts2 mini let me
tell you about the gts2 mini so this is the most budget budget version of a smartwatch in the mass
fit smartwatch range you can get it for as low as 80 pounds or 80 bucks that is very cheap that's
cheaper than the fitbit inspire 2 which is a tracker a fitness tracker but this is a full-blown
smart watch you get a lot of functionality so you get continuous heart rate monitoring you
get three sleep stages you get uh spo2 monitoring in fact it's on demand or spot exposure readings
but nonetheless it's there you get continuous 24 hour heart rate monitoring you get 70 sport modes
which is absolutely huge you get inbuilt gps it's an amoled display and it's sharp it's quick the
contrast is deep the picture is just take a look for yourself i think it looks really good for the
money i don't think you can get anything close to it well except for the huawei watch fit which was
actually just recently dropped in price as well and you can see a card just above my head now
if you want to go off and watch the review of the huawei watch fit but coming back to the gts2 mini
for 80 bucks you get a lot of value with this smartwatch and what we actually noticed as we're
doing these reviews and comparisons is that the optical heart rate sensor on the gts2 mini
is better than most of the smart and sport watches under 200 bucks so it does have a claim to fame
on top of that just recently at the start of march this year the ota update came through and finally
the mass fit smartwatch brand well starting off with the gts2 mini actually gets alexa with alexa
you can store your shopping list with alexa you can set alarms you can ask it for jokes you can
ask the directions the weather forecast etc the fact is you do have a microphone on the gts2 mini
so just say what you want to say into here to alexa and alexa will come up with an answer so
let's look at the numbers now as soon as we start the workout we can see that the smartwatch heart
rate sensor sort of follows on with the polar h10 ecg strap but then about two minutes later
it just drops it basically drops and stays at that low level except for one spike at the four and a
half minute mark all the way till we get through 70 percent of the actual workout in terms of time
and then we can see convergence between the heart rate plot on the a mass gts2 mini smartwatch and
the polar h10 ecg chest strap so we can see that for the last four and a half five minutes
the heart rate plots were actually closed and you can see some follow through but still for most
of the chart you can see a huge understatement of the heart rate as measured by the amazon gts2 mini
so i know that this is a bit of a shock to most of the people who've been
looking at the tests and comparisons we've been doing with the gts2 mini thanks for watching this
review comparison and test i know that the numbers are not exactly great but i'm here to review and
test and give you the real feedback of what these watches do show now i've also outlaid the problem
the issue is it's not just with a mass fit watches as we go and do these tests in regards to physical
workouts with other brands you'll see that they do have problems as well but nonetheless the gtr 2 as
against the gts2 mini that's what the results are be aware take note of it but i have to say
that the gtr2 and the gts2 mini heart rate sensors are usually very good and i've shown great results
when i'm out running or when i'm doing circuit training anyways thanks for watching if you
