How to Pick the Best Fitness Tracker with a Heart Rate Monitor

All fitness trackers are not created equal when it comes to tracking your ticker. Here are the key factors to consider when selecting a fitness tracker with reliable heart rate monitoring:

Accuracy of Heart Rate Tracking

The first thing to examine is the accuracy of the heart rate monitoring technology. Look for validated sensors from leading companies like Fitbit, Garmin, and Apple that provide precise real-time heart rate data.

Many fitness trackers use photoplethysmography (PPG) which shines light into the skin to detect blood volume changes. Some higher-end models also have multi-path optical heart rate sensors utilizing multiple LED lights for better accuracy.

Brands may discuss clinical studies done to test their trackers against gold standard chest straps to give you confidence in their accuracy.

Ability to Measure Heart Rate Zones

The next spec to check is whether the tracker provides insights into different heart rate zones like resting, fat burn, cardio/aerobic, and max heart rate.

Viewing time spent in zones helps optimize workouts and measure intensity. Look for trackers that break down your heart rate data into at least 3-5 zones.

Display Quality

Consider the display size, brightness, and crispness so your heart rate data is easy to read on the go. Full color OLED or AMOLED displays offer excellent clarity.

Smart Notifications

Many fitness trackers double as smartwatches so you can get call, text, and app alerts right on your wrist. Handy for keeping tabs on notifications during workouts.

Battery Life

For continuous heart rate tracking, look for 5-7 days of battery life between charges. Longer for basic interval monitoring. Quick charging capabilities are also useful.

Water Resistance

Swimproof design (5ATM and above) allows tracking heart rate during pool sessions or open water swims.


Fitness trackers range from $100 to $400+ based on features. Determine how much you want to spend for the functionality you need.

Leading Brands

Stick with reputable fitness wearable brands like Fitbit, Garmin, Apple, Samsung, and Polar for the most accurate and reliable heart rate tracking.

By keeping these factors in mind, you can zero in on the best fitness tracker with heart monitoring for your individual needs and budget. Let’s look at our top picks.

Frequently Asked Questions about Fitness Trackers with Heart Rate Monitoring

How accurate are the wrist-based heart rate monitors on fitness trackers?

The latest optical heart rate sensors from reputable companies like Garmin, Polar, Fitbit, and Apple provide very accurate results when worn properly, often within 1-2% of an ECG chest strap. They use multiple LEDs and advanced algorithms to measure pulse from blood flow changes.

Why does my fitness tracker’s heart rate reading sometimes differ from a chest strap monitor?

Factors like improper wearing position on the wrist, tightness of band, skin tone, tattoo coverage, and movement during exercise can affect optical sensor accuracy. Chest straps remain the gold standard for accuracy, but fitness trackers still provide very good results.

What are the different heart rate zones and their meaning?

Resting heart rate: 60-100 bpm Fat burn: 100-134 bpm, light intensity for burning fat Cardio: 134-170 bpm, moderate to vigorous exercise strengthens cardiovascular system Peak heart rate: 170-220+ bpm, intense training and intervals

Knowing your zones helps optimize workouts and measure intensity/exertion.

What’s the best way to wear my fitness tracker for the most accurate heart rate reading?

Wear the band 1-2 finger widths above your wrist bone and ensure a snug fit on your skin. Avoid wearing on bony areas of the wrist. The closer it sits to blood flow in the veins the better reading it will get.

How often does my fitness tracker record and measure my heart rate?

Most fitness trackers either measure continuously or at periodic intervals like every 10 minutes. High end trackers record real-time heart rate data with high frequency. Check specs to understand how your tracker samples for heart rate.

Will my heart rate measurement be impacted if I exercise vigorously?

High intensity exercise can sometimes impact optical sensor accuracy. But brands use proprietary algorithms to maintain accuracy even with high bpm. Chest straps can provide the most precise data during intense activity.

How long will the battery last with continuous heart rate monitoring?

Expect 5-7 days of battery life with continuous HR tracking, less for advanced smartwatch models. It varies based on features and specs. Disable continuous HR if you don’t need 24/7 monitoring to extend battery.

Can I track my heart rate accurately while swimming with my fitness tracker?

Most fitness trackers are waterproof enough for swimming and provide accurate enough underwater heart rate data. Look for a 5ATM or higher water resistance rating. Swimming-specific HR chest straps are more reliable.

Can I pair external heart rate monitors like chest straps to my fitness tracker?

Many fitness trackers allow you to connect an external Bluetooth heart rate monitor like a chest strap for added accuracy and better tracking during intense exercise. Check your device’s compatibility.

Are fitness tracker heart rate measurements reliable enough for medical purposes?

While today’s fitness trackers provide good insight into heart health, doctors still recommend clinical-grade ECG monitors for detecting and diagnosing medical conditions. Seek medical guidance rather than self-diagnosing with consumer wearable data.
