Best Fitness Trackers with Heart Rate Monitors in 2021

The Fitbit Charge 3 is the best Fitbit for most people because it does almost everything well, is comfortable to wear for long periods, and doesn't break the bank. Its always-on heart rate sensor is accurate and doesn't eat into the battery, which, in our tests, lasted longer than the advertised five days.

The Vivosmart HR+ is a reliable activity tracker that can track a multitude of different types of exercises, from basic running and biking to more extreme sports like snowboarding, all while using the built-in GPS.

If you're looking for something that is a little more hybrid smartwatch and a little less fitness tracker, the Nokia Steel HR is a great option. It looks like a traditional analog watch with a round face and comes with a step tracker, workout tracker, heart rate sensor, calorie counter, sleep tracker, and more.

The M430 can monitor the essential metrics that many marathon runners would be keen on, like pace, distance, speed, and cadence. However, that doesn't mean the M430 is a slouch when it comes to other activities. You can take it for a swim thanks to its 30m water resistance, it'll track your sleep for you, and its built-in GPS is good for pretty much any outdoor activity.

The heart rate sensor on the back of the Apple Watch is accurate, fast, and able to scan your heart rate so you can always keep an eye on it. The Series 5 also has the all-new Always-On Display. The Workout app is a fantastic way to track all your metrics while you sweat at the gym. Plus, Apple Watch syncs up all that data with your Apple Health account, so you can keep track of all your workout sessions over time, giving you a great overall view of your fitness level.

Fitness trackers are great, but if you don't feel like spending a ton, your options are pretty limited. Thankfully, LETSCOM makes an excellent budget tracker that'll set you back a lot less. It has heart-rate and sleep monitoring, all-day activity tracking, 14 different exercise modes, and shows notifications from your phone.

Want to take your fitness tracking to the next level? Check out the Garmin Vivoactive 3. Not only does it track your steps, calories, miles, and more, but it presents all of the data it collects on a gorgeous color touchscreen display. The Vivoactive 3 can also monitor your stress levels, has up to 7 days of battery life, and supports contactless payments via Garmin Pay.

The Ionic may be Fitbit's most powerful smartwatch, but the Versa is our favorite. Its design is sleek, lightweight, and looks equally fantastic with a sport or leather band. The touchscreen display is great, you can get four days of use in between charges, and you can get guided workouts right on the watch itself. The Special Edition version even has Fitbit Pay!

The Ionic is very similar to the Versa, but it has built-in GPS, so you don't need to have your phone with you at all. This makes it better for runs and other situations where you may not want to have your phone on your person. It also has better battery life at over five days on a single charge.

If you want a Fitbit but are on a budget, then the Inspire HR is a great option. It's a simple and sleek looking fitness tracker with 24/7 heart rate monitoring built-in. You'll be able to track all of your daily activity with it, including steps, calories, workouts, sleep, and more. It can notify you of things happening on your phone as well and has five days of battery life.
