Best Heart Rate Monitors iMore 2020

Some great benefits come with wearing a heart rate monitor while you work out. It can provide you with the most accurate stats, including optimal heart rate zones, fat burning zones, and calorie burn so you can really get the most out of your training sessions. Most heart rate monitors also connect to smartwatches, fitness trackers, and fitness apps so you can track and record your progress overtime to get a better understanding of your overall fitness and reach your training goals. We love the Polar H10 Heart Rate Monitor. It's highly accurate, waterproof up to 30 meters so you can wear it swimming, and features great connectivity. Plus, it has built-in memory so you can work out without your phone, then download your stats later.

Best Overall: Polar H10

The Polar H10 is one of the most accurate and popular heart rate monitors on the market. It works with everything and can connect to many sports and smart watches, the affiliated app: Polar Beat, and tons of different fitness apps such as Strava and Nike. It is compatible with all heart rate monitoring cardio equipment so you can connect to your favorite machines at the gym as well. It is widely recognized for its top precision and is the most accurate heart rate sensor in Polar's history.

It uses Bluetooth, ANT+ and 5 kHz to provide excellent connection options. You can use Bluetooth and ANT+ connections simultaneously as well as two Bluetooth connections simultaneously, so you never have to worry about missing a chance to connect and record your data. It's compatible with Android and iOS. This heart rate sensor also features built-in memory for one training session, so you don't always have to bring your phone on your workout and can download your data later.

You wear the Polar H10 around your chest. It's easy-to-use and has silicone dots on the back; it stays put when you're on the move. It's soft, interference-free, and comfortable to wear and made of 38% Polyamide, 29% Polyurethane, 20% elastane, and 13% polyester, so it's machine washable. It's also suitable for swimming and is waterproof up to 30 meters.

On the downside, this sensor is worn around the chest (for accuracy). Some people prefer being able to wear their heart rate sensors in a more convenient location like the arm or the wrist. Some also find it annoying to have to wet the back every time they want to use it.

Pros:

  • Highly accurate
  • Waterproof up to 30 meters
  • Great connectivity
  • Built-in memory

Cons:

  • Must wet the back to get sensor to work
