The best heart rate monitors are an excellent way to keep track of your fitness levels and a valuable measure of your workout intensity. With models worn around your chest or on your wrist, these devices collect data to help you make sense of your health and fitness levels. 

Our heart rate can tell us much about our health, with resting heart rate as a critical indicator. However, it’s also essential to watch how we exercise this muscle, as we don’t want to train too intensely, but hard enough to improve our performance. 

Some of the best heart rate monitors are designed to be worn around your chest for the most accurate measurements, like our top pick, the Polar H10 chest strap. This monitor plays nice with most mobile devices and fitness services, plus you can analyze your heart rate data in the Polar Beat app. 

However, many of the best heart rate monitors come integrated with fitness trackers and smartwatches, so you get the added features and convenience of all-day monitoring from your wrist. But with so many options out there, it can be hard to know where to start. 

That’s why we’ve found the best heart rate monitors for a range of styles, budgets, and uses. You don’t have to go hunting for the lowest prices either, as our shopping technology automatically finds the best deals available right now for you.

How to choose the best heart rate monitor for you

When looking for the best heart rate monitor for your needs, there are a handful of considerations you need to take into account, like the accuracy of the measurements and the type of monitoring you're after. 

Heart rate monitor style

There are two types of heart rate monitor for tracking your fitness levels; chest straps or wrist-worn monitors. Each uses a different technology to keep tabs on your heart rate, with chest straps generally giving the most accurate readings.

However, you’re also not likely to wear a chest strap all the time. If you’re looking for a way to monitor your heart throughout the day, then wrist-worn devices like fitness trackers and smartwatches are the most practical option.

Heart rate monitor accuracy

Chest straps, like the Polar H10, use electrocardiography to track your heart rate. This reads the electrical signals from your heart in a similar way to monitors you find in healthcare settings. As it follows your heart directly, this is generally seen as the most accurate measure.

Wrist-worn options use optical sensors on the underside of the unit to infer your heart rate. This process, known as photoplethysmography, monitors blood flow by flashing green LEDs against your skin and using sensors to track the amount of light absorbed.

As your blood flow is generally lower between beats, the wrist-worn heart rate monitor uses changes in blood flow to estimate your heart rate. This method isn’t as accurate as chest strap monitors, but it is a convenient approximation.

Reasons for monitoring

Before investing in a heart rate monitor, it’s essential to consider why you want to track your heart and when. If improving your sports performance is your highest priority, then a chest-based monitor might be the best for you. 

Meanwhile, those considering one of the best heart rate monitors for health-related reasons or improve their general fitness may find wrist-worn options to be the most ideal. These are a great choice as they include other useful features. 

Fitness trackers and smartwatches come with health and fitness features like step counting, sleep tracking, and working monitoring. They also tend to integrate with your smartphone to get notifications or control apps from your wrist.

Battery life: 400 hours
Water-resistant: 30m
Weight: 60g
Reasons to buy
+Precise heart rate tracking+Great for any activity
Reasons to avoid
-Chest strap can be uncomfortable

Most chest straps offer precision heart rate monitoring but the Polar H10 is by far the most reliable and competent of the lot. Similar trackers often support one of ANT+ or Bluetooth, but the H10 supports both so it'll happily link up with any watch or mobile device you use, simultaneously if you like.

If you don't want to wear a watch or carry your phone on a workout, that's fine too – the H10 will record and store your heart rate data onto on-board memory, so you can download it later.

Polar's fitness ecosystem is superb – the Polar Beat app is tailor-made for analyzing your heart rate and helping you improve your fitness, but the H10 will play nicely with all the other major fitness apps too. In short, this one-size-fits-all option is perfect for anyone who wants precision data.

Without question, the Garmin Forerunner 945 sits at the top of the pile when it comes to functionality – this watch is designed for hardcore triathletes, so Garmin has packed it with every trick in the book to help you reach peak performance. 

There's an optical heart rate monitor under the hood so yes, it will struggle to get accurate data if you're HIIT training or playing sport, but you can connect a chest strap monitor to it directly if you need to.

For runners and triathletes, it's an absolute powerhouse – it records and analyses a staggering amount of data, from your running cadence and stride length to your VO2 max and training load and effect. If you're serious about taking your performance to the next level, this is the watch for you.

If you want solid, dependable heart rate monitoring without the bells and whistles of the Polar H10 or the Garmin Forerunner 945, the Wahoo TickR will be just the ticket. With the more expensive (but equally excellent) TickR X leading the way with extra features, Wahoo's budget heart rate monitor does an outstanding job of the basics. 

It's comfortable to wear, gives you accurate, real-time heart rate and calorie data, and dual band ANT+ and Bluetooth connectivity means you can have it linked to multiple devices at once. It tracks heart rate variability too (that is, the variation in time interval between consecutive heart beats – another indication of heart health). A very worthy budget option.

This watch tracks your HR 24/7 (including during sleep), and uses these stats to calculate your ‘Body Battery’, a figure that represents how much energy your body has for the next workout session. 

The lack of in-built GPS means this is not aimed at runners – instead, it’s an affordable option for those doing gym-based workouts who like an idea of how hard they push themselves.

For those who want to track health metrics and get more detailed, accurate feedback on things such as calories burnt and VO2 Max, the Fitbit Sense packs more than most into its stylish frame. 

Your heart rate is tracked every five seconds, and it can be programed to alert you if your HR goes over, or drops below, a certain rate, which is useful if you suffer from arrhythmia. It also features an electrocardiogram sensor (ECG) which can be used to check your heart for atrial fibrillation. 

Another useful HR-based feature is its ability to use your heart-rate data, combined with your sleep info and your palm’s electrodermal activity, to give you a score on your overall stress rating. Based on that score, the Sense will then recommend mindfulness sessions if the numbers are too high.
