With time Apple Watch has become a completely everyday smartwatch. But while they do a great job of processing your notifications and providing third party applications, the true cream of the Apple Watch smartwatch when it comes to tracking your activity. The Apple Watch heart rate monitor is the topic of our review.
Through the Apple Activity app, you can review the basics like calories burned, active minutes, and how many hours you've moved during the day, while Workout handles more detailed sports tracking. And this is where the smarts of the Apple Watch heart rate monitor are most prevalent.
But how does it all work, what data is presented on the wrist and on the iPhone, and how accurate is the tracking? Well, below, we have provided the answers to all your questions.
Almost every smartwatch that has a heart rate monitor uses the same technology, and the Apple Watch is no different.
Photoplethysmography, as we know, essentially works on this premise: blood is red because it reflects red light and absorbs green light. Therefore, by using green LEDs and pairing them with photodiodes, the device is able to detect the amount of blood flowing through the wrist. When your heart beats, this flow, and green light is absorbed through a proxy, is greater. Between beats, meanwhile, it's less.
To get the most accurate BPM data, these LEDs flash hundreds of times per second. This technology is also used during the Watch's Breathe app, which focuses the user's attention on relaxation, as well as new with watchOS 4, providing insight into walking average BPM and heart rate variability.
However, it is not only during bouts of exercise that the heart rate monitor is in action. It can also use infrared light to measure heart rate in background and gives you a heads-up if your heart sinks to dangerous levels.
Data on your wrist
When you wear the watch, you give your continuous heart rate reading during your workout and can also view your average heart rate for your entire workout once you're done.
But if you're just at your desk and want to see how your heart is doing, head to the Clock Watch app, which also gives you insights into your rest, walking, and overall speed throughout the day. You can even jump straight into the app from your watch face by adding a complication like the one below. Don't know how to do this? Head over to our guide to gathering information about the Apple Watch. 
These screenshots above show exactly what you'll get on the Watch. The left screen shows the heart rate widget on the watch face, while the middle and right screen shows how the heart rate is read. The little graph above the measurement, meanwhile, gives you an idea of how your heart rate is changing throughout the day. But that's not all, as slipping will give you access to your daily rest rhythm and average walking course.
Apple Watch calculates these metrics by matching readings taken in the background with accelerometer data. As with the standard heart rate screen above, the mini graph will show you how it has changed throughout the day. Interestingly, your daily resting heart rate is something that only appears after a couple of hours in the device. This figure will change as the amount of data increases throughout the day, with readings taken when the device detects that the user is still staying for a few moments. 
It's even smart enough to not take a reading when, for example, your heart rate is still slightly elevated from your morning sprint for the train. Regarding heart rate, things are a little clearer. Whenever the watch detects that your heart rate is elevated, say, while walking to get lunch, it will be recorded to give you an idea of how your heart is working.
Users also have the option to receive notifications when Apple Watch detects your heart rate rising above, such as 120 beats per minute, when you find yourself inactive. The easiest way to enable and adjust this is in the Watch app title on your iPhone, scroll down to Heart Rate in the My Watch section, and change the settings to match your ticker.
Data on the phone
As you'd expect, the data captured and presented on the Watch is also enhanced on the iPhone.
If you want to view heart data from completed workouts, you'll need to go to Activity—this gives you a more detailed graph of how your heart rate fluctuated throughout the activity, as well as how your heart recovered in the three minutes after finishing the exercise. Let's take the information below as an example. The red markers on the graph show that the heart rate develops as the exercise progresses, with a break when pausing before resuming and continuing to track your heart rate. If you swipe, you will have access to heart rate recovery. The faster your heart returns to a steady pace, the healthier your cardiovascular system will be.
But while these are useful ways to give you a more detailed look at your heart rate, the downside is that there is no real interpretation of this data. For example, if you have a measure of when your heart rate was high, there is no difference in how much time you spent in each heart rate zone or any data regarding VO2 Max.
Moving on from heart data tracked through exercise, you can also get deeper data analysis that doesn't affect rest speed, average walking rate, or overall heart rate on iPhone. Again, you can't view the history of these metrics in the Watch, so going to the Heart section Apple Health” will give you a comprehensive overview of each of these sections.
As shown below, you can choose how your heart performed on an hourly, daily, weekly, monthly, or yearly time frame, and pressing the "i" on each tab takes you to a more advanced graph, helping you pinpoint specific readings. 
Third Party Applications
You can get a pretty detailed look at your heart thanks to Apple's own tracking, but there are dedicated third-party apps that aim to make up for some of the shortcomings discussed above. Both Cardiagram and HeartWatch will give you a live look at heart rate zones, for example, as well as providing a more detailed view of your heart rate history on the watch itself.
And this action is not limited to heart health. Fitness platforms that support heart rate tracking, such as Strava, can use the technology to better interpret your data - ideal for those who don't want to use native applications for Apple tracking.
Apple Watch Heart Rate Monitor: Let's Talk About Accuracy
This all sounds good in practice, but it all comes down to whether it can actually provide accurate monitoring from the wrist.
And for the most part, the Apple Watch makes a smartwatch that fits any watch-fit wrist on the market. In the end, although the same technology is used to collect data, it is how it is interpreted that results in accuracy or inaccuracy.
Through our Watch vs Chest testing over the past few years, we've found it to be one of the more consistent performers. However, this does not mean that it is free from the same limitations as others that use optical sensor technology. That is, when fast movement between low and high beats per minute during intense intervals, he may often struggle to keep track of time.
In our experience, such as the example below, we tend to see the average heart rate a little higher than the number given by the chest straps, but it's not that much if you just want to keep your beats on the base tab. 
It's also worth noting that to get the most accurate results, you'll need to make sure the fit on your wrist is correct. This means you can't be too tight or too loose. Your skin should be in constant contact with the sensors, but with room left for your skin to breathe.
Apple Watch Heart Rate Monitoring: What's Next?
Apple has pivoted to health and fitness lately, announcing its research into atrial fibrillation and offering more health features like notifications and an Apple Watch heart rate monitor through the watch.
But big step here is an upgrade of the current photoplethysmography method for ECG monitoring, a medical grade currently found in chest straps. And according to reports, this is a development that could show its face through Apple Watch Series 4, if Cupertino can obtain the customer's required FDA. While ECG monitoring is considered more accurate than current wrist-based methods - good news for trainers - it is also more effective at detecting cardiac abnormalities and potentially notifying users of problems before they become more severe.
If this is indeed something Apple delivers sooner rather than later, expect the data to be available to users to take a big leap forward. And for those of you who can't wait for ECG technology to hit the wrist, startup AlivCor has already developed a belt-based solution, the Kardia Band, that can give users readings.
After talking with a former professional athlete (tennis player), I realized that when playing sports it is important to know your pulse; depending on the heart rate, the body most effectively performs different functions.
For example, if you need to burn fat, keep your pulse in the range from 112 to 131 beats per minute (average indicator), if you just warm up - 94-112 beats per minute, cardio training - 131-150, increased muscle growth / endurance training - 150-169.
Who is interested in the continuation - go under the cat.
That’s when I decided to buy at least some kind of heart rate monitor, since I like to pedal (15-50 km almost every day during the season) + roller skate at the All-Russian Exhibition Center.
A walk through sporting goods stores made it clear that you can’t buy anything for less than $30, and good heart rate monitors generally cost $100 and more. I abandoned the idea for a while, especially since I accidentally came across the Cardiograph phone application, which can measure the pulse using the phone’s camera (by the way, it copes well with the task, I tested and compared the readings together with good blood pressure monitors).
I bought this watch by accident. I bought several items from one seller at once, and decided to add something to the pile in the parcel. I looked in his store and came across them. The price is ridiculous (196.22 rubles), without hesitation I ordered one to try.
While we were walking, I looked for reviews on the internet and found a site where 4 people left their opinions about similar watches. Moreover, three of them were negative and mostly consisted of crybabies (no backlight, the menu is not feng shui, putting your finger on is not comme il faut, they don’t look good with a jacket, and anyway, this is China!), and the fourth, from a girl, said that she constantly trains in the gym and am happy for hours - they perform their function well, the measurements are more or less accurate, and for this price there can be no competitors or shortcomings.
I confess, then I believed these whiny reviews more, and thought that what would probably come was complete crap.
Hours passed for 1.5 months, I won’t announce the tracks and exact dates, I don’t even see the point in it. We're not discussing the work of the post office :)
When I received it and opened it, I didn’t take a photo either; no one is particularly interested in a standard white or yellow envelope with a bubble inside. In it, wrapped in 4 more layers of bubble wrap, lay a watch + a simple instruction sheet in English. All this packaging, along with the instructions, immediately went into the trash, and I began to inspect the watch. I was surprised that in the seller’s picture the watch has the inscription WR50M (water resistant to 50 meters), but my watch doesn’t have it, apparently there wasn’t enough paint. But I wasn’t particularly upset, I wash my hands in them every day - they seem to hold water, but there are others for diving.
I’ve been wearing this watch every day for more than 2 weeks and then there are pictures with explanations, I’ll put them under ONE spoiler. I won’t warn about traffic, I think it’s at least pointless - 99.9% of users nowadays are still on unlimited.
Different angles. 
Regular clasp 
The back cover is without inscriptions. 
The inside of the strap has a white coating - the epidermis is renewed :) 
The strap is on the other side. 
Functions. The first screen is the current time + date, mode display (sounds and alarm are on). The transition between screens is carried out by pressing the “Mode” button. 
The second screen is an alarm clock, as you can see mine is set to 12:00 at night. 
The third screen is a simple stopwatch. 
The fourth one, the most incomprehensible for me, is the calorie counter during sports. You can enter your age (date of birth DD/MM/YYYY) and height into the watch, turn on this function - it will count the calories burned. In my opinion, it’s complete crap, so I don’t use it and don’t even understand how it works. 
The most important thing is the heart rate monitor. 
On the first screen, when you press the Start/Stop button, the time display mode changes from 12 to 24. 
And here we have a heart rate monitor sensor. 
Him, close-up. Regular IR sensor. 
By the way, I noticed that the paint began to peel off and the inscription SENSOR turned into SENSOP.
Not lethal :) 
Buttons on the other side. 
Hand view. 
Pulse measurement is simple - select the mode with the MODE button, press and hold the SET button, it sounds sound signal and the word TOUCH SENSOR blinks on the screen. We put our finger on the sensor, wait 10-20 seconds and the measurement results appear on the screen. I didn’t film the process itself, but I took the results and even compared them with the “reference” iPhone :) Data after measuring the pulse. 
For variety - a photo with another watch on your hand that came to hand 
And measure the size using a tape measure. 
Conclusion: whoever needs it can take it, they cope with their function, the appearance is not repulsive, the price is ridiculous.
I decided for myself that I would then buy a watch with a chest sensor, so that I could monitor my heart activity while moving, like
Nowadays, in the world of smart technologies and smart portable devices, optical sensors still find their use and have important. In this article we will look at some devices and technologies created using optical sensors.
