Best Fitness Trackers with Heart Rate Monitors 2021

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 6 also has the all-new Blood Oxygen app, letting you check the oxygen levels in your blood, and 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 your overall fitness level.

If you're looking for 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 Fitbit Charge 4 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 lasts around seven-days.

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 Fitbit Versa 2 has a sleek design; it's lightweight and looks equally fantastic with a sport or leather band. The touchscreen display is great, you can get at least six days of use in between charges, and you can get guided workouts right on the watch itself. The Special Edition version looks even better with the unique woven fabric band.

The Apple Watch SE is a great entry-level smartwatch for those who want to upgrade from an older model or get their very first Apple Watch. With the Apple Watch SE, you get 24/7 heart rate monitoring, as well as Fall Detection and Emergency SOS, and you can track all of your workouts with the Workouts app. watchOS 7 also lets you track your sleep every night too.

Fitness trackers are great, but your options are pretty limited if you don't feel like spending a ton. 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. You also get six beautiful colors to choose from, including pink and green.

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.

If you want a Fitbit but are on a budget, then the Inspire 2 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 a whopping 10 days of battery life.
