What is the best watch for heart rate

We Tested the Best Heart Rate Monitors: These 9 Came Out on Top

From optimizing your workouts to managing your heart health and stress levels, there are plenty of reasons to use a heart rate monitor. Analyzing the data collected from a monitor can help you track your progress and better communicate with coaches, personal trainers, and healthcare professionals. To find the best heart rate monitors, we consulted experts (including a sports medicine physician and certified personal trainers) to learn which key features are the most important. Then, we tested 15 expert-approved heart rate monitors at home for over 187 hours.

We prioritized monitors that are easy to use, accurate, and comfortable to wear. We also looked for devices with a long battery life, a comfortable fit, and accurate readings. Our top picks earned high scores for their ease of setup, comfort, precision, battery, connectivity, additional features, and value.We also had an emergency physician from our Review Board review this article for accuracy, including how to read data from a heart monitor and how they can enhance your health and wellness routines.

Types of Heart Rate Monitors

There are three types of heart rate monitors:

• Chest strap monitors detect your heart rate using wireless electrode sensors that are tightly pressed against your body. They typically provide the most accurate numbers, but the band can feel constricting and irritating across your chest.
• Armband monitors are secured with a strap around your upper arm or forearm. They use optical sensors, so theyre usually less precise than chest strap monitors. But theyre more comfortable to wear for longer workouts, especially in hot weather.
• Wristband monitors also use optical sensors, so theyre slightly less accurate. However, theyre easier to put on and less obtrusive, so they can be worn for longer periods of time. Some of these monitors can also track your sleep data and recovery after exercise.

Who Its For

Best for beginners who want to start tracking their heart rate while exercising.

Why We Love It

After testing 15 heart rate monitors, Polars H10 Heart Rate Sensor is by far our favorite. With built-in memory, precise readings, and extra-long battery lifeplus Bluetooth and ANT+ compatibilityit has everything you need to enhance your workout routine. Setting it up is a cinch: We just had to download the user-friendly app and pair the device with our phone via Bluetooth.

The H10 uses ECG monitoring to track heart rate, producing highly accurate readings during our test runs, weight training sessions, and other workouts. The chest strap, which features grippy silicone spots that keep the sensor close to your chest, feels soft, comfortable, and secure. Even during a hot and sweaty vinyasa yoga class, we didnt notice any slipping or irritation. We also love that the monitor doesnt require frequent recharging since it comes with a fully charged batterythat lasts up to 400 hours, according to Polar.

Potential Flaws

• We like that the app makes it easy to track your statistics on your phone. But, unlike most wristband monitors, this one doesnt have a screen where you can view metrics as you work out.
• This monitor can only be worn on your chest, making it less versatile than some other options on our list.

Who Its For

Best for fitness enthusiasts who want a heart rate monitor with accurate tracking but not a huge price tag.

Why We Love It

If youd like to try using a heart rate monitor but dont want to make a huge investment, we recommend CooSpos H9Z Chest Heart Rate Monitor. This budget-friendly pick delivers accurate readings and has a decent battery life that rivals some of the more expensive devices we tested. Once we charged the device, it was quick and simple to set up. We just had to snap the sensor into the chest strap and choose one of two apps to download.

The monitor stays in place, thanks to the soft, comfortable strap, which didnt cause any irritation or chafing during testing. We also love that the readings were precise every time during different workouts. Although it cant be worn for swimming, the monitor is waterproof and held up to our sweatiest sessions.

Potential Flaws

• We noticed that the apps associated with this monitor arent the most functional. We wish they had more advanced features, or that this device could connect with other, more detailed apps.
• We had some issues trying to pair the device with our phone for the first timewe wish the instructions for setting up a Bluetooth connection were more clear.

Who Its For

Best for anyone who cross-trains and needs a monitor that can be worn in different ways.

Why We Love It

Myzones MZ-Switch Heart Rate Monitor is our pick for the most versatile device because it can be worn on your chest, arm, or wrist. After initially charging the monitor, it was easy to set up, and we were using it in minutes. Using Bluetooth or ANT+ connectivity, you can pair it to the MyZone app or compatible third-party apps, watches, and exercise equipment. And if you want to run, swim, cycle, or do another activity without your phone, the monitor saves 36 hours of exercise data that you can view after your workout.

When its worn on your chest, this monitor uses ECG sensor technology to provide very accurate metrics. But we also found that its fairly reliable when worn on your arm or wrist. One of our favorite features is the LED light that indicates your current heart rate zone in real timewhich definitely pushed us during workouts. We also appreciate the robust workout data displayed in the app, including your calories burned, average heart rate, peak heart rate, and heart rate zones.

Potential Flaws

• The one-size-fits-all armband may not be large enough for some users.
• We liked the flexibility of being able to wear the monitor on our chest, arm, or wrist. But the wristband can be a bit uncomfortable, and we had to adjust it to keep it secure during workouts.

Why We Love It

Polars H9 Heart Rate Sensor is easy to use andhas both Bluetooth and ANT+ connectivity, making it our top choice for cyclists who want to connect to a smartwatch, activity tracker, or exercise machine. During testing, we were immediately impressed with this monitors intuitive setup process. It took us less than five minutes to unbox it, put it on, and pair it to our devices. We were also surprised to find that the Polar app has robust features that make it easy to view and analyze your data.

The chest strap feels comfortable during bike rides, and we like that this monitor provides accurate and consistent readings every time we use it. Plus, you never have to worry about it running out of juice during a race, since the sensor has a replaceable battery that lasts up to 400 hours, according to the manufacturer.

Potential Flaws

• While the strap stayed put for low-impact workouts, like cycling, yoga, and strength training, we noticed that it slipped a bit during our runs.
• The chest strap provides very accurate readings, but we wish the monitor could also be worn on your arms or wrists.

It can be used to detect atrial fibrillation, bradycardia, tachycardia, and normal sinus rhythm in just 30 seconds.

We found the monitor easy to set up and use by just placing two fingers on the small pads, with no gels, wires, or patches needed. We also like how you can view the data on a smartphone or tablet using the KardiaMobile app. Color-coded alerts make interpreting your results simple. Plus, the device is small enough to fit in a pocket, so its convenient to bring with you while traveling.

Potential Flaws

• Unlike other monitors on our list, this one cant continuously track your heart rate during exercise because it isnt wearable.
• The monitor is easy to use, but its very sensitive to movement. We noticed that if you move your fingers even a little bit, the reading is disrupted and you have to start over.

Why We Love It

Many heart rate monitors are suitable for runnersbut Wahoos Tickr Fit Heart Rate Armband is our time-tested favorite for its comfortable design and powerful functionality. Once we set up the Tickr app, the armband monitor was easy to use. During test runs, it accurately tracked our heart rate (including our average and maximum heart rate) in real time. We also like the GPS tracking feature, which analyzes where your heart rate changed during your runs.

We were pleasantly surprised by the monitors sleek design and comfortable fit. The breathable strap is easy to adjust and can be worn either on your forearm or upper arm. Even better, this monitor is compatible with over 50 fitness apps, including Stravaplus, it will record your data in both the app of your choice and the Wahoo app every time you run. This device is also waterproof and has a 35-hour battery life with each charge, for robust tracking capabilities even on your longest, toughest runs.

Potential Flaws

Why We Love It

For a seamless user experience and a comfortable chest strap, its tough to beat Garmins HRM-Pro Plus. The setup is a breeze, as the monitor automatically pairs with your phone, smartwatch, or cardio machine (including the Peloton Bike and Tread). We love that you don't have to charge anything, press any buttons, or turn anything on. Even if you aren't wearing your watch, the monitor still captures your heart rate data, as well as steps, calories burned, intensity minutes, and more, feeding it into the Garmin Connect app continuously.

The soft, adjustable strap fits securely and doesn't cause any chafing or irritation. Its so comfortable that its easy to forget you have it on (we almost wore it into the shower!). The battery lasts for up to one year and when its time to replace it, the tool-free battery door is easy to use.

Potential Flaws

• Like some of our other picks, this monitor doesnt have a screen. Youll have to use the app to access things like your data and the monitors battery life.

Why We Love It

Specifically designed for swimming, Garmins HRM-Swim heart monitor is our top pick for laps in the pool or open water. We love that the lightweight, sleek design causes minimal drag as you swim. Plus, we like that the strap is made with a non-slip material that stays securely in place, even during turns in the pool.

The HRM-Swim stores heart rate data when youre swimming and forwards it to the Garmin app when youre done. With a simple setup process and very precise data, it impressed us in more ways than one. We also like the 18-month battery life, which makes forgetting to charge your monitor a problem of the past.

Potential Flaws

• While we found the tracking to be accurate, we wish you could view your data in real time while you work out.
• This monitor can only be paired with other Garmin devices.

Who Its For

Best for triathletes, especially if real-time tracking is important to you.

Why We Love It

Scosches Rhythm24 Waterproof Armband Heart Rate Monitor is our top pick for anyone whos tackling triathlon training. This lightweight heart monitor uses optical sensor technology to accurately track your heart rate, cadence, distance, calories burned, and more. Designed with soft, rounded edges and no exposed seams, the armband strap is ultra-comfortable and breathable.

During testing, we liked how easy it was to switch between different activities in the app. We were also impressed by how quickly it detects a change in your heart rate and gives results in real time. Plus, the 24-hour battery life means you dont have to worry about keeping it plugged in all the time when youre not wearing it.

Potential Flaws

• It took us several tries to connect this monitor to our phones during testing. But once we got through the initial setup process, we realized that the device was pretty easy to use.
• We like that this device has LED lights that show what heart rate zone youre inbut they can be difficult to see during a workout. We think sound alerts might be a more useful indicator.

Heart Rate Monitors We Also Tested

We tested 15 heart rate monitors, but only nine earned a spot in our final list of recommendations. While these devices do have some notable features, they ultimately fell short:

• Although powrlabs Heart Rate Monitor Chest Strap is budget-friendly and easy to set up, we dont like that we had to download third-party fitness apps to view the data it collects. We also wish the strap was easier to adjust.
• iFits SmartBeat Forearm Heart Rate Monitor was accurate and comfortable during testing. But it doesnt have a display, so you cant see any of your data or battery life on the device itself.
• Wahoos Tickr Heart Rate Monitor Chest Strap feels comfortable to wear during a variety of activities and has an impressive battery life of 500 hours. However, we had some connectivity issues that made it frustrating to use.
• While we liked Coros Heart Rate Monitors sleek, streamlined design,we found that the straps are difficult to adjust. We also wish it could track more metrics than just your heart rate.

Where We Stand

After testing 15 heart rate monitors, Polars H10 Heart Rate Sensor isour clear winner for its reliable accuracy, comfortable fit, and excellent battery life. We continue to test all of the monitors on our list at home, and we'll update our recommendations if we find anything significant that we havent already mentioned here.

What to Look for When Shopping for Heart Rate Monitors

• Style: The choice between a chest strap, an armband, and a wristband often comes down to personal preference. Armbands and wristbands are usually more comfortable for long training sessions, but chest straps tend to provide more accurate readings.
• Activity: Which workouts do you need a heart rate monitor for? If you like to swim, make sure to choose a waterproof option. Runners may need GPS navigation. Also, make sure the device is compatible with all equipment and technology you use (whether thats your own or the gyms), recommends certified personal trainer Chris Gagliardi.
• Accuracy: If youre using your monitor to make sure youre training in a specific heart rate zone, youll want one thats reliable and precise. Chest straps that use electrocardiography are generally the most accurate. Optical heart rate monitors, like wristbands and armbands, can also be reliableas long as you get a secure fit.
• Connectivity: Some monitors use ANT+ technology, a wireless system thats compatible with most exercise machines (like those made by Peloton). Others use Bluetooth, which makes it easy to connect them directly to your smartphone.
• Metrics: Heart rate monitors can also track your speed, distance, stride length, breathing rate, blood pressure, and other metrics. Consider which data is most useful to you before buying. If youd like to track your statistics over time, look for a device that can be synced to an app or collects data you can download to your computer.

How We Tested the Best Heart Rate Monitors

Weve tested 15 options from popular fitness brands to find the best heart rate monitors. When testing heart rate monitors, we evaluate each device based on these key criteria:

• Ease of Setup: After unboxing the monitor, we note how easy it is to set up. Does it come with batteries? Are the instructions clear? If the device requires an app, we download it and consider how easy it is to use.
• Comfort: During our workouts, we evaluate how comfortable the monitor is to wear. Does it fit securely? How does the material feel? Does it cause any irritation or chafing?
• Battery: How long does it take for the monitor to charge completely? If the battery is rechargeable, we pay attention to how long it lasts on a single charge. Does the battery last through at least one full workout? How easy is it to change the battery when it dies?
• Precision: Before working out, we take our own pulse manually while wearing the device and compare our number to the devices reading. Is it accurate? We also check the numbers during and after exercising. Does the monitor provide real-time data, or is it delayed?
• Connectivity: Which devices, apps, and gym equipment can the monitor connect to? Is the pairing process straightforward? We also consider how reliably the monitor transmits data to connected devices and platforms. Can we easily access and download our data?
• Additional Features: If the monitor comes with any additional features (like GPS or sleep tracking), we test those, too. Are the settings and features customizable?
• Overall Value: To assess each monitors value, we wait to check its price until the end of the testing period, after weve rated it in all other categories. Then, we weigh the cost against its quality, features, and performance. Monitors that wed gladly pay full price for earn higher value scores.

Frequently Asked Questions

How do heart rate monitors work?

Most chest strap monitors use electrocardiography to measure your hearts electrical activity, while armband and watch-style monitors use photoplethysmography, a process through which small LED lights measure blood flow through your skin. With both types of monitoring, the collected data is then transferred to a receiver (such as a watch or an app), so you can view your heart rate in real time.

How do you read heart rate monitor results?

Many people use a heart rate monitor while exercising to hit their target heart rate zone and get the most out of their workouts. Some basic monitors just relay your heart rate, so its up to you to know your target zone based on your age and fitness level. Other, more high-tech devices can alert you when you reach your target zone and send reminders when you drop below or go above it.

Whats the most accurate type of heart rate monitor?

Chest strap heart rate monitors detect electrical signals emitted from each heartbeat, so they usually produce the most accurate results. Optical heart rate sensors, which are usually worn on your wrist or arm, can also be reliable. Note that both monitors need full contact with your skin and should be secured in place to provide the best reading.
