Heart monitors allow you to keep an eye on your heart without having to rely on your doctor. They are incredibly handy for all sorts of situations, such as tracking your heart rate during exercise or while you’re relaxing at home.
Over the last few years, heart monitors have been transformed from bulky, unsightly devices you have to strap to your chest, to stylish, discreet devices packed with cutting-edge features to give you the full picture.
Modern heart rate monitors give you as much information as you need about your health. They record your heart data for you and allow your doctors and other healthcare practitioners to easily access the information without having to call you in for an appointment.
As with any sort of tech equipment available these days, there are many heart rate monitors from which to choose. They come in all different shapes and sizes. So how do you know which one is right for you?
This comprehensive guide will help you find the best heart rate monitor to meet all your needs.
Buying A Heart Rate Monitor
Optical Wrist Sensors vs Chest Straps
First of all, you need to decide how you want to wear your heart rate monitor.
Chest straps use electrical pulses to measure your heart rate. Wristbands use optical sensors and other technology to measure your heart rate.
Optical sensors are responsible for making wearables like Apple Watch and Fitbit gadgets easy to use. They are very accurate, making them useful to use in other applications to measure heart rates.
Wearable heart rate monitors are also available with LED lights to show you how hard your heart is working. Each color represents the heart rate zone you are in.
Wristbands are far more convenient and comfortable than chest straps, but since they aren’t placed directly on your chest, they are not as accurate as those devices. Knowing this, more brands are creating wearable heart rate monitors that are positioned higher on the arm in order to provide more reliable readings. Of course, you then need to make sure it is firmly enough attached to your arm to remain in place during intense exercise.
Ultimately, it is up to you how you wish to measure your heart rate and what type of device is most comfortable for you to wear.
This is one of the most important factors to consider. It’s no secret that wristbands and wearables are more comfortable than a chest strap and won’t chafe your skin. They fit easily on your arm and can be adjusted to your preference even when exercising.
Chest straps must be strapped tightly to your chest to stop it from sliding out of place. If not well attached, it will stop reading your heart. Refitting the strap takes longer than a wristband so, if you’re in the middle of your workout, the adjustment can be more time consuming to perform. However, make it too tight and it will chafe your skin. So care is required.
The tradeoff is ease of use and possibly greater comfort with wristband monitors versus the added accuracy of chest straps but with less ease of adjustment for comfort.
ANT+ vs Bluetooth
ANT+ precedes Bluetooth. It has become standard issue for workout machines like treadmills, cross trainers and more. Low-end heart rate monitors use this technology too, but this restricts how well it can connect with other devices. Heart rate monitors that use Bluetooth can sync with smartphones and other devices, giving you more control over tracking your progress.
Modern heart rate monitors can do more than just measure heart rate. They can also be used for fitness trackers, EKG, ECG and even to track your sleep. The more features in a device has, the more help it offers about your health. Of course, the more advanced features also come with a bigger price tag.
With these factors in mind, here is a list of the top 10 best heart rate monitors to buy right now.
Fitbit Charge 3

Fitbit is one of the biggest brands in the smartwatch and fitness tracker industry, and the Fitbit Charge 3 is one of their best. It doubles as a fitness tracker and a heart rate monitor. Other features include being waterproof up to depths of 50m (164 feet), it looks great and it also provides pretty accurate readings.
The Charge 3 uses Fitbit’s all-in-one approach. It utilizes PurePulse technology to monitor your heart rate and, thanks to its SpO2 sensor, it can monitor your sleep, too. This sensor is so robust that it can be used to diagnose sleep apnea.
Like most fitness bands and smartwatches, Charge3 will count your steps, distance travelled and how many calories you’ve burned. Plus, if you start to feel tired from the day’s activities, Charge 3 is programmed to take you through breathing exercises to prevent you from fainting.
In terms of usability, Charge 3’s touchscreen is around 33% larger than that of the previous model, making interaction even easier. The battery life is very good and the device uses your phone’s GPS for connectivity. The Charge3 is customizable too, with multiple colors and styles to choose from, so you can match it to your outfit.
Other features of the Charge3 include the ability to choose from more than 15 exercise modes to track your progress. The list includes running, cycling and swimming, to name a few.
Overall, this is a great device. It has many features that will keep you motivated to achieve better health. If you’re looking for a heart rate monitor that can do it all, with a battery that lasts more than a week, this is the one for you.
Strong battery life – the battery is very powerful and will give you 7 days’ worth of power before needing to be charged. Use it all week without worrying about running out of juice.
Great interface – Fitbit Charge3 has a larger display, increasing in size by more than a third compared to the previous model. Seeing more about your health on the screen and interacting with the device is easier than ever.
It has SpO2 sensors to analyze your sleep and provide you with the ultimate sleep tracking package. Fitbit is attempting to become the industry leader for sleep tracking. There’s a good reason to do this: your sleep can tell you many things about your health. For example, if your sleep is easily disrupted, Charge3 can help diagnose such conditions as sleep apnea.
24/7 activity tracking ensures you can track your heart rate and overall health at any time you need to do so. It makes sure you are always on top of your fitness and health.
You can take it anywhere, including the swimming pool. It can resist depths of up to 50m (164 feet).
Charge3 doesn’t come with built-in GPS. This is surprising considering most smartwatches and heart rate monitors do come with this technology.
It may not be able to keep up with high-intensity activities. However, Charge3 will give accurate readings for running, working out in the gym and other light sessions.
Finally comes the Omron HeartGuide. However, just because it’s the last devices on this list, doesn’t mean that it’s the worst of the bunch. It’s actually one of the best.
HeartGuide offers a range of features to monitor your health. It is packed with a heart rate monitor, sleep tracker, blood pressure tracker, and fitness tracker. All of these features are contained into a sleek, stylish smartwatch.
In particular, its blood pressure monitor is one of the best there is. Typical trackers use inflatable cuffs that are uncomfortable to wear. HeartGuide is the opposite. Its second strap fits great and acts as a miniature cuff, making it easy to take a blood pressure reading while on the move. HeartGuide reads your diastolic and systolic pressure with high accuracy in a matter of seconds.
There are also many other features, such as tracking how many steps you take throughout the day, how far you have walked/run/cycled, etc., and how many calories you have burned.
The sleep tracker tells you the quality of your sleep, how long you were sleeping, your daily sleep pattern and more.
Finally, HeartGuide sends push notifications via a companion app on your smartphone to give you updates on your heart rate and other fitness information.
HeartGuide is certainly a device you should consider buying for a fantastic, all-in-one heart rate monitor.
Easy to use – HeartGuide is very comfortable to wear and use compared to other blood pressure devices on the market.
State-of-the-art sensors are well positioned in the device, meaning it provides very accurate readings that are so accurate that its reliability closely compares to heart blood pressure readings given by equipment used in major hospitals.
You can see how your heart health compares to American Heart Association guidelines.
More than tracking – it can help you diagnose any signs of sleep apnea
Furthermore, the FDA has cleared this device to use for health tracking to give you extra peace of mind.
Multi-purpose – it can watch your sleep, track your fitness, tell you how many calories you’ve burned and monitor your heart and blood pressure.
HeartGuide is larger than other smartwatches and fitness trackers. People with smaller wrists may find it easier to wear something else.

Why You Need A Heart Monitor
Here are some of the main reasons you will benefit from a heart rate monitor.
Measuring Workout Intensity
The American Heart Association says that monitoring your heart rate is important for two reasons: it tells you how hard you are working and whether your overall fitness is improving over time.
Sure, there are other methods for measuring workout intensity. Measuring how hard you are breathing after so many minutes of an exercise, or how tired you are can be useful. However, heart rate tracking is the most reliable method to judge progress from your workouts. Plus, heart rate monitors create data that can be analyzed from multiple angles, giving you deeper insights into your health and fitness levels.
Working out too hard and overtraining can lead to injury and put unnecessary stress on your heart. Heart rate monitors allow you to workout safely so that you can readily tell when your heart is working too hard and you can quickly change behavior to reduce its load.
Advanced heart rate monitors can also tailor your workout by demographics, such as your height, weight and age group – thus making your workout more effective and keeping you safe from injury.
Being Your Own Personal Trainer
Heart rate monitors can act as your own personal trainer. A monitor can tell you when you are ready to increase the intensity of your workout, when you need to tone it down a bit or when you’ve hit the sweet spot.
Modern heart monitors are also very accurate, so you can use one as encouragement to know you are on the right track and doing the right thing.
Using As A Recovery Tool
When you finish your workout, you need to give your body plenty of time to rest and recover before working out again. Heart rate monitors can indicate when you’re ready to go again. This is because raster recovery rates are a sign that your heart capacity is increasing, also indicating better fitness and overall health.
These are some of the main advantages of using a heart rate monitor but there are plenty more. No matter whether you want to improve your workouts or you need to manage a heart problem, heart rate monitors provide ideal assistance.
The next part of this guide will show you what you need to look out for when choosing a heart rate monitor.
