It also integrates nicely with the Apple Watch, making it the best heart rate monitor for Apple Watch that we tried.

Though this item does a fantastic job at measuring heart rates, it does not measure body core temperature or other fitness-related metrics. Additionally, the internal storage is on the small side, with only enough to save data from one fitness session. The best fitbit will also help you stay fit.

On that note, the related software also provides dynamic feedback, which is particularly useful when running, as it measures cadence, vertical oscillation and ground contact time, among other metrics.

Though this monitor interacts nicely with compatabie ANT+ devices, it does not feature Bluetooth, which somewhat limits connectivity.

We also loved that the device features both Bluetooth and ANT+ connectivity options.

How We Decided

To help narrow down to the above list we focused, first and foremost, on heart rate monitoring capabilities, favoring products that produced accurate results via optical heart rate sensors and those that were precise enough to create a reliable ECG measurement. We also liked items that could complete its monitoring tasks during intense workouts, even when the skin tended to be sweaty.

We also made sure that we included a number of items that were perfect for a large variety of exercises, including cycling,running and even swimming. To that end, many of the above products monitor many metrics in addition to heart rate, including running cadence and steps taken. For swimmers, we included several waterproof monitors, with waterproof certification up to 10 meters, that are ideal to wear while taking some laps in the pool.

As far as additional functionalities, several of our picks also double as smart watches, meaning they can perform a number of useful tasks that go above and beyond health and fitness, including sleep tracking, message storing and programming alarms, among other tasks. Finally, we liked well made items manufactured using durable and long-lasting components, including long-lasting batteries that get as much as 20 days of use on a single charge.

Best Heart Rate Monitor Buyer’s Guide

The Most Important Features to Consider

  1. Monitor Type
    Heart rate monitors come in a variety of different shapes and sizes, each varying in functionality and efficacy. Generally, monitors that attach to the chest via strap are considered to be the most accurate, thanks to the proximity to the heart itself. Optical sensors, that measure heart rate via skin analysis, are often worn around the arm and, though slightly less accurate than chest monitors, are a great alternative for consumers who do not feel comfortable with something strapped around their chest. Smart watches often do a decent job at monitoring heart rate, via a similar design to armbands, though they can struggle with accuracy. We made sure all of the watches on the above list were up to snuff.
  2. Additional Metrics
    Many of the above heart rate monitors go above and beyond simple heart rate calculations. Our top picks, for instance, excel with a wide variety of fitness based metrics, including cadence, vertical oscillation, ground contact time and heart rate variability (HRV.) Other monitors can accurately measure sleep, steps taken and offer specific information catering to cyclists and swimmers.
  3. Other Features
    In addition to being equipped with high quality sensors and electrodes for the measuring of fitness metrics, many of the above products pull double duty as standard pedometers. Some can also measure sleep quality and the smart watches we featured go even further, allowing for the reading and storing of text messages, music playback and even, in some cases, video games.
  4. Waterproofing and Water-Resistance
    Don’t just buy anything that says “waterproof” or “water-resistant” on the packaging, as there are several factors to consider. If you are looking for something that won’t malfunction thanks to sweat or a quick, and accidental, trip in the rain, then anything with water-resistance IP67 or IP68 certification should be sufficient, as these items can be submerged in a meter or a meter and a half of water for up to a half hour. If you are looking to go swimming in a pool or the ocean, however, you are going to want something more extreme. Look for extremely waterproof, not water-resistant, products, such as our number two pick.

Heart Rate Monitor FAQs

What is the most accurate heart rate monitor?

Of all the products we tried, our top pick was the most accurate heart rate monitor, thanks to a suite of advanced electrodes and a chest-strap design. Generally speaking, chest strap heart rate monitors produce the most accurate results.

Which fitness tracker has the best heart rate monitor?

Fitness trackers tend to be “jack-of-all-trade” devices, so you are likely to not get quite as accurate a result as a dedicated heart rate monitor. Still, all of the fitness trackers on the above list produced precise and accurate results, despite being placed on the wrist and not near the chest.

Are heart rate monitor watches accurate?

Heart rate monitor watches usually use optical sensors to measure the heart beat. This creates a fairly accurate result that should satisfy the lion’s share of consumers. If you are looking for extremely precise results, however, you may want to invest in a chest-based monitor that uses electrodes to measure the heart rate.

What is the best heart rate monitor on the market?

We tend to think that all of the above products are excellent. If we had to pick just one, however, we’d go with the Polar H10 Heart Rate Monitor, our top pick.
