a cheap smart watch might not have every feature possible,
but it's still sufficient to keep your tech loving heart happy.
Haylou RS4 - the watch with an amazing amoled screen, also referred as the Haylou LS12
it's a great entry-level smartwatch and the price won't break the bank!
welcome back, this is Adam - and you're watching #FamilyPopTV youtube channel.
in today's video we will put the newest Haylou rs4 into few real-life tests;
i will challenge its heart rate accuracy as well as spo2 and step count accuracy
this is something i couldn't find in the other video reviews on youtube
and i will check if it's really waterproof and will show you through its main features.
i even traveled to eastern Slovakia to check how it performs during heavy physical activities such as chopping wood!
so if you want to take a closer look at the RS4 - stay with me.
Haylou is the Chinese brand that's been growing in popularity
and it's known for fantastic true wireless noise cancelling earbuds and affordable smart watches,
and brands that we immediately associate with Xiaomi.
and that's right, because Liesheng and Haylou became the members of Xiaomi ecosystem,
and they are major players in the smart consumer technology industry in China.
inside the aesthetic looking box we can find the watch itself, a manual and a warranty card and the usb charging cable.
unlike the Haylou RT2, which i reviewed recently,
the RS4 has a square design that looks very clean and elegant in black
and it's suitable for both, men and women,
and features a smooth 2.5D curved Gorilla Glass in the metal frame with a brushed finish.
it certainly doesn't look like a budget watch!
the body is slim and light and made of high quality aluminium alloy, which makes it lightweight at just 48.6 grams and therefore comfortable on the wrist.
if we flip the watch, you can see the magnetic charging port to fuel up the smartwatch,
and the two heart rate sensors and the infrared spo2 sensor in the center.
at the side of the watch there's one multifunctional button.
the strap on the RS4 is made out of silicon lightweight and comfy on the wrist for long lasting use.
obviously, you can customize the look of your RS4 by replacing the 20 millimeters bands of your choice.
i personally like the magnetic straps or leather straps.
there are Amazon links in this video description where you can find some good looking alternative straps for your RS4.
my favorite part of Haylou RS4 is its phenomenal 1.78 inches 1000 nits AmOLED display with 368 by 448 pixels resolution.
the RS4 has the same display resolution as the display of the Apple Watch 6.
however, the Haylou RS4 hasn't gotten always-on screen, unlike the Apple Watch 6.
anyway, this is probably the best screen i ever seen in a budget smartwatch up to date,
in terms of size, resolution and sharpness of the image,
and certainly puts into shame displays of any other budget watches in this price range.
the brightness of the display is adjustable, it has four steps and to clarify, this is not an always-on display as i said before,
however, it lits up automatically when you move your wrist up.
the RS4 smartwatch has an ip68 water resistant design,
so in order to verify if the watch is suitable to use in a swimming pool I prepared a simple waterproof test.
the RS4 is being submerged in the water for a couple of hours and we will see if it survives.
as you can see, the screen getting a bit crazy underwater, certainly the water interacting with the screen.
some kind of screen-lock feature would be beneficial here.
hopefully Haylou going to take it forconsideration during the next firmware update.
the ip68 of our tested unit should guarantee protection in water up to one and a half meter deep for at least 30 minutes.
it also means, that our watch is resistant to dust.
this is only a simple waterproof test, just to verify the water resistance capability of our Haylou RS4,
because we want to be absolutely sure, before we take in the watch to the pool.
after about four hours being submerged in water, the watch is absolutely fine,
it definitely survived the water challenge.
that proves you can wear this watch while swimming.
i did wear it in a jacuzzi - i even took it to the swedish sauna however it's not recommended,
as micro particles of the steam can penetrate the seals of the watch, which means water will get in but won't get out.
luckily, the watch survived all the water exposure.
so the conclusion - you can wear this watch while you're swimming, however it hasn't got any sport mode to track the swimming exercise.
talking of which, the Haylou RS4 offers the assortment of 12 sports monitoring modes which includes:
- jogging, - fast walking,
- biking, - climbing,
- spinning, - yoga,
- indoor running, - integrated training,
- gymnastics, - basketball,
- football, - and rowing.
the watch doesn't have a built-in gps, which means, when you turn on different sports modes like run or bike for outdoors,
you need your phone's gps to connect the smart watch for tracking routes and distance covered
simply start the walk-in or running exercise from the companion app and this will help tracking the root of your workouts accurately.
so with that being said, let's look at the accuracy of the pedometer in RS4:
i've been testing the watch step count using a manual tally counter.
i have done exactly 1000 steps, manually clicking the tally counter for each step,
and the Haylou RS4's count is pretty decent, nearly spot on.
in the first trial, for manually counted thousand steps of various length, walking with various speeds using the stairs, etc, etc.
the RS4 captured 994 steps, which gave us a 99.4 percent of step accuracy, that's great!
in the second trial i tried some fast walking with the high paced steps of the same length:
and the RS4 captured 997 steps - and this gave us 99.7 percent of step accuracy - that's impressive!
don't forget this is still an entry-level budget watch.
i know it's a bit crazy, but i have traveled to Slovakia and checked out, how does the watch behaves during heavy physical activities,
in this case i've been chopping wood logs!
to measure it i have chosen the "integrated training" exercise,
in around 12 minutes i burned almost 100 kilocalories,
so it's twice as much as i would burn during jogging or fast walking in the same time,
anyway, i really enjoyed this activity.
the RS4 uses the Haylou Fun companion app, that you install on your phone,
which is where you set and control most of the functionality of your RS4.
Haylou Fun app itself is a simplistic tool for tracking the activity and health stats,
you'll have to scan a QR code with your smartphone to get to the apple store or google play,
as the app is compatible with both iOS and Android.
once the app is installed, make sure you got your bluetooth turned on in your phone - but do not connect with the watch from the bluetooth screen,
you'll have to do it from the app: click on "add device", then click on Haylou RS4,
then just confirm pairing request and allow the notifications,
as this will push all the data from your phone into the watch.
in the comments for our previous videos some of you been asking - "can i use the watch without a phone?"
- well, yes and no - because when you first get your RS4 it requires the phone to set it up,
once this is done you might leave it connected, so it will work as an extension of your phone,
but you may also disconnect the bluetooth,
so when the watch will work as a standalone device, you won't get any messages, notifications, weather info, and health stats,
and the health and sport statistics will be reset on a daily basis as watch hasn't got enough storage to keep it in.
by the way, the RS4 shows you all the notifications from the phone,
for example, sms, social apps messages, info messages from the apps like youtube, linkedin, tiktok, etc.,
the watch also shows you the incoming calls.
however, you can't pick the incoming call as the watch hasn't got a microphone built in, you could only drop the incoming call.
the main menu in the Haylou RS4 combines little icons and widgets,
and the first icon is the daily sports stats,
and the second icon is the heart rate measuring.
the RS4 tracks the heart rate continuously 24 hours a day,
but let's check out how accurate the heart rate on the spo2 measurements actually are against the NHS approved medical pulse oximeter
in the first attempt Haylou RS4 measured my heart rate as 75 beats per minute, and the oximeter measured exactly the same value.
right, just to be sure - let's try it again.
as you can see, both devices going head to head giving us exactly the same measurements.
right, let's check it again - but this time i'll do some press-ups to raise my heart rate a bit.
but remember, even if the readings are so close, don't forget the watch isn't a medical grade device,
so these readings should be taken only as a reference.
here we go: RS4 measured 108 beats per minute and the oximeter measured 108...109 beats per minute, that's fantastic!
okay, one more go,
and here we got: - Haylou RS4 measured 102 bpm, i'm cooling down now and the oximeter measured 99 beats per minute,
these are actually fantastic results.
right, let's check the blood saturation measuring.
this is the next icon or the next widget right after the heart rate.
you have to manually trigger the Sp02 tracking.
and here we got: 97% of Sp02 on RS4 - and 98% of Sp02 on the oximeter. let's do it again!
right, and we got 97% of Sp02 on both devices, i'm totally happy with this.
you can customize the watch faces or change built-in watch faces for the new styles,
to create your own dial, you can use any photo or picture from your smartphone;
simply pick it, crop it and select the best color of the font - and it's ready to upload.
the RS4 has a bunch of useful features, such as weather indication,
by the way it works only when the watch is connected with the phone.
the music app control - you could switch between the songs from your phone, change the volume and the watch can show you the title of the songs.
one - or - two minute breathing exercise, which is nothing more than respiratory minute volume,
which helps to calm down and help to reduce the carbon dioxide levels within the body,
the watch has also got a sleep tracking, however i wasn't able to scientifically test the sleep tracking accuracy.
i've been wearing my RS4 to the bed over the last three weeks, and the watch struggled a bit with the sleep tracking;
it recorded the deep sleep and the light sleep periods,
but sometimes struggled with recording the actual length of my sleep, often showing less hours than i actually slept.
out of curiosity, i have checked what existing users have to say on amazon about the Haylou RS4,
and here we got: - "very good watch, exceptional display, excellent materials very good features, the best you will find for this price" - i fully agree.
next one: - "AmOLED screen, very nice smartwatch recommended".
there's one from Mexico:
- "en un articulo muy bonito, pero poco útil" - which means: "nice product, but not very useful"
- and why is that? - "it's not working for me, since it gives me different measures against a huawei mi band 6"
- right, you might question the accuracy of the other device.
next one: - "large screen and good colors" - yes, that's the AmOLED, you need to see it to believe it!
- "ideal for the first approach to smart watches" - yes indeed,
- "good for the price" - absolutely.
