How Optical Heart Rate Sensors Work

Are Smartwatch Heart Rate Monitors Causing Skin Irritation?

The vast majority of wearables use a photoplethysmography sensor the green LEDs you see when you flip the device over. The LEDs shine light into your skin the light thats refracted back is translated by an algorithm into heart rate data. That includes your resting heart rate but also other metrics like VO2 Max and heart rate variability.

While optical heart rate sensors have gotten better over the years, wrist-based PPG sensors still arent always accurate. A recent study found that these sensors didnt work as well on darker skin or people with obesity. The wrist is also not the best place for a PPG sensor. Theres a lot of noise from your arm movements, and a companys algorithm has to be able to effectively filter that out. Thats why you could wear the same smartwatch on each arm and still get slightly different readings.

Fit is also an important factor. It varies from smartwatch to smartwatch, but here are a few general tips for getting the most accurate data possible.

  • Wear the watch about one finger length above your wrist bone
  • Make sure theres good contact between the sensor array and your skin
  • Tighten the strap during exercise. You may also want to wear the device higher on the wrist.
  • Wipe the sensor array clean whenever it gets dirty

Many smartwatches, including the Fitbit Versa 3, will allow you to view heart rate from your watchface

Buy A Good Smartwatch

Often people buy Inexpensive smartwatches to save money, but when it comes to essential features like heart rate monitoring, you should go for a good smartwatch.

Cheap smartwatches do not use good quality sensors for cost-cutting, due to which they do not provide you with accurate heart rates.

In contrast, premium smartwatches like the Apple Watch are expensive but provide high-quality sensors that give you accurate heart rate data.

So if you are serious about heart rate monitoring, choose a good smartwatch.

Lots Of Functions Missing

Yet, not everything in the garden is rosy. If you wanted to connect it to one of the most accurate pulse straps, or another external sensor, you come to a harsh stop. And there are no music streaming services. Even though you can find skipping rope amongst the sports, there isnt a strength training mode or even an other solution. The data fields displayed are extremely restricted and you cant really change them and the same thing applies to the various dials and the information they display. At the same time, some parts of the watch work slowly. When we find the GPS position before a run and hit start, the entire watch goes blank for a couple of seconds before the counter begins.

The biggest disadvantage is in the interface. Theres no major problem with the interface, even though its a bit confusing to know when youre supposed to use the touchscreen or the buttons. But the interface is impaired by a touchscreen that reacts pretty much when it wants to. Swipes become clicks and vice versa – and sometimes the screen doesnt react at all.

The Amazfit Stratos is a watch that wants to, and indeed can, do a lot. And it often does work well. But there are an equal number of times when we come to a stop because the function we expect just isnt there.

The Fitbit Charge 4 Is The Fitness Tracker For Monitoring Your Heart

The Fitbit Charge 4 is among the best fitness trackers you can buy, and it packs a fairly accurate heart rate sensor. While the is now available, we cant quite recommend it purely because of heart rate inaccuracies experienced during our . That said, it trumps the Fitbit Charge 4 in several other areas, so it might be worth a look if youre seeking a solid all-around tracker and fancy its ECG smarts.

Back to the 4, you can grab this device in two colorways, either black or Rosewood, and each comes with two band sizes, small and large. It features a monochrome, OLED, touchscreen display with plenty of room for viewing stats. On the inside, its packed with features including built-in GPS. This alone makes it a strong choice for runners and cyclists who dont want to carry a phone during workouts. Throughout testing, we found the GPS performed well, though it did take a few minutes to lock on when trying to start our outdoor workouts.

We also tested the Charge 4s heart rate sensor on those same runs and compared its data to that of a Garmin running watch. Though the Charge 4 struggled to keep up during sprints or excessive slowdowns, it matched up better than we even expected. Keeping in mind this is an affordable device and not a dedicated heart rate monitor, we were pleased with the data. The Charge 4 provides a good overall look at your active heart rate. For a tracker you can often find around $100, this is a great pick for basic data.

Specialist Heart Health Wristwatches: Omron Heartguide

Some wearables go beyond this, making heart health their USP.

The Omron HeartGuide is one such device and was marketed as the world’s first clinically validated wearable blood pressure monitor.

It promises to monitor your blood pressure, steps, distance, calories and sleep, and it displays some notifications from your smartphone. Omron says the HeartGuide can also measure your heart rate, but it will do so only when you ask it to measure your blood pressure.

You’ll need nimble fingers to take it on and off, though, which you’ll need to do each time you want to do the washing up or go for a swim. It can survive being splashed with water while you wash your hands, if you’re careful, but it can’t survive being submerged in water. The watch also feels heavy and cumbersome.

Note that Omron says you shouldn’t use the Heart Guide if you’ve had a mastectomy. Traditional blood pressure monitors can carry similar warnings.

But how did it fare in our lab tests? Find out in our full Omron HeartGuide smartwatch review.

When Apple Watch Measures Your Heart Rate

When you use the Workout app, Apple Watch measures your heart rate continuously during the workout and for 3 minutes after the workout ends to determine a workout recovery rate. If you don’t see your heart rate, check your settings.

This information, as well as other data it collects, helps Apple Watch estimate how many calories youve burned. In addition, Apple Watch measures your heart rate throughout the day when youre still, and periodically when youre walking . Since Apple Watch takes these background readings based on your activity, the time between these measurements will vary. Apple Watch also calculates a daily resting rate and walking average by correlating background heart rate readings with accelerometer data when sufficient background readings are available.1 You can control which third-party apps have access to your health data from the Health app in Sources.

Garmin Vivoactive 3 Music

Garmin has painted themselves into a bit of a corner with their Vivo models, which run from the simplest activity tracker up to Vivoactive. They quite simply have a confusing range of series in completely different models, beginning with the Vivo and followed by Smart, Sport, Fit, Active and the list goes on.

Good App Poor Mobile Connection

When it comes to the associated software, the Vantage M has benefited enormously from being able to mature. The truly exhaustive analysis functions for exercise, sleep and daily activity that were introduced in the budget Ignite watch are also included here. You also get notifications from your mobile, even though they regularly stopped working on both iPhone and Android during our tests. At the same time theres no fixed connection to the mobile. When you finish a session you must manually synchronise it to your phone or computer .

The analysis functions deserve a special mention. Because when it comes to sleep measurement, nobody provides as much detail as Polar. Combined with built-in sessions for stretching, simple strength training and condition based on the watchs assessment of your well-being and exercise, this is really good.

A lot of the functionality has been added over the years for the Vantage M, and as both a pulse watch and an everyday activity assistant its become very intelligent and good value for money. For the everyday fitness enthusiast theres really everything you need here, but if you want a better connection to your mobile or perfect accuracy in how GPS routes are recorded, this may not be the watch for you. But despite that this is a very competent pulse watch and associated app, and in terms of price its a good choice for those with a slightly tighter budget.

Good Exercise Without Setting Options

As long as the correct sport is on the watch, training is fine. But you simply cant set what should be shown on the screen while youre exercising. After exercising the sharing options are very poor and its a challenge to get your data out of it.

The disadvantages continue in the software. The limited functions make the interface easy to navigate, but you cant set which data should be shown on the various dials. Notifications dont work all that well either. Sometimes you see the name or number of the person calling, and sometimes not. Sometimes it shows which app is trying to get your attention, and sometimes not. Sometimes the notification is shown, and guess what? Sometimes not.

The Huawei Watch GT has taken a brave sidestep by starting something completely different from previous models. But it feels like the watch has been released too early in the development process to be able to give other smartwatches or pulse meters a serious run for their crown the biggest plus point will remain its battery life.

Theres An App For That

Apple’s attitude towards health, exercise and activity differs a little from the industry standard. In the case of activity, this is a good thing. Instead of steps, which are actually quite difficult to find, its all based on three rings to be filled: Standing, moving and exercise. Filling the rings every day feels both more varied and motivating than the classic step goal, because in the case of the Apple Watch, it works more on the basis of what you do overall.

In the case of health, on the other hand, things arent so good. The attitude is very much that if theres nothing wrong, you dont need to be told anything. You can take your ECG and even measure the oxygen level in your blood, which is one great new feature for the Series 6. But at the same time, you dont get any of the values unless it seems as if something may be wrong.

The health app in both the watch and on the iPhone is awfully messy. Viewing your history of what you’ve done and getting tips to improve your performance is almost impossible.

Unfortunately, the same applies to the new sleep measurement. Sleep isn’t an exact science, but the only thing you actually get out of Apple’s sleep measurement is knowing when you fell asleep and what time the alarm clock rang in the morning. Light/deep sleep, nocturnal visits to the loo or any assessment of sleep quality is completely lacking. However, there are third-party apps that deal with sleep a bit better.

Its Going To Be Good In The End

N58 ECG Blood Pressure Heart Rate Monitor IP67 Smart Watch Fitness

Just like the Classic model, Wear OS 4 is the name of the game. The latest version of Googles smart watch system, and a much-needed update of that system. Apart from being alone on that version for a few six months or so, Samsung does not seem to be gaining much from it.

The Tizen system they previously used was very well developed, had advanced notification management, lots of functions, and a really good app deal. Its about the same here, but now the clocks are run using some sort of 24 hour battery life. Its a third of what the Tizen watches could do, and they were really quick. Samsung Galaxy Watch 4, on the other hand, suffers from a lot of lag and sluggishness, especially during start-up and when the battery is low.

At the same time, logically all the developments will be focused on Wear OS 4, which means that it is completely pointless to buy any other older Wear OS watch. At present, updates to these are looking bleak, so at the time of writing, Samsung watches are the only future-proof choice.Samsung Galaxy Watch 4 is a good exercise watch, a good health buddy, and a good smartwatch. The disadvantage is that it feels like a clear step back, primarily in terms of battery life, compared to previous models from Samsung. At the same time, its the regular Watch 4 that you should choose in terms of price.

Its All In The Software

When it comes to workouts, everythings familiar. A lot of data is collected and can be displayed both during and after a workout in more or less any way you want. The types of workout covers most things, including golf, and the great screen in combination with a fresh interface means you now get really useful information on the watch itself. One of the new workout aspects is HIIT mode and updated animations for yoga and strength training to show you how to perform exercises.

For running, you can follow a training programme and have the watch tell you what you should do, which it spills over to the area of “daily health”. There we find things like steps, heart rate, sleep, stress and the like. The touchscreen allows us to easily fill in the meter for fluid intake and the like. Garmin’s Body Battery has been completely redone and now actually feels quite consistent with how fit you feel. Among the exercise modes you will find, a little confusingly, both a breathing exercise and Health Snapshot. The latter checks all the watch sensors for two minutes to give you a full battery of health data, where really only the ECG is missing.

When To Talk With A Doctor

There are several instances when you should talk with a doctor about your heart rate, especially if its too low or high.

According to Smiley, Anytime you have a low heart rate , and feel dizzy, tired, or pass out, you should definitely see a doctor. If the heart rate is 50 beats or lower, even without symptoms, you should seek medical help.

She also notes that you should talk with a doctor if your heart rate is over 100 beats per minute when youre at rest or if its over 100 beats per minute and youre experiencing symptoms like dizziness, anxiety, or heart palpitations.

Are Heart Rate Monitoring Watches Accurate

Several factors can affect the accuracy of heart rate monitoring watches, including the specific brand, your activity level, and the position of the sensors on your skin .

Though heart rate monitoring watches arent as precise as medical devices, such as electrode-containing chest monitors, theyre generally accurate and can be a useful tool to help track your heart rate (

Poor Screen And Mediocre Battery Life

Are smartwatch heart rate monitors as accurate as a medical-grade device?

The watch is about the same size as many other multisport watches. The design feels modern, but the screen is quite poor from some viewing angles. From straight in front its clear in all environments, but as soon as its on a bit of an angle it isn’t so clear.

To get all the downsides out of the way at once, its also worth mentioning that the interface feels slow and the battery doesnt last as long as competitors if you run a lot. It isnt exactly catastrophic, but with lots of activities, its a day or two shorter than the average watch. Despite the fact that Suunto were once first with apps in pulse watches, theres no such functionality in their current watches, which is a shame. This also applies to the dials, and there werent enough included to suit all of our testers tastes.
