Wirecutter’s Best Smartwatch Fitbit Charge 3 Fitness Activity Tracker

Fitbit Charge 3 (3)

Fitbit Charge 3 is our best-reviewed smartwatch, hands down. It features advanced tracking, a built-in GPS, and an always-on display. But the Charge 3’s biggest draw is its ability to sync directly with iPhones and Android phones. The Charge 3 is the latest and greatest in Fitbit’s lineup. It has more advanced features and offers a new sleek design.

A smartwatch is a great way to track your health, stay connected, and receive alerts about things happening at home or at work—but choosing the best fit isn’t easy—Wirecutter’s Best Smartwatch Fitbit Charge 3 Fitness Activity Tracker. The Charge 3 is the latest and greatest in Fitbit’s lineup. 

Introduction Fitbit Charge 3

This week, Wirecutter editor and long-time fan Ben Tarnoff took us on a tour of the best smartwatches out there. The Fitbit Charge 3 has everything you need in a wrist-based device for tracking your daily activity and sleep.

its screen displays steps, distance, calories burned, active minutes, and so on. But while this is a great addition to any smartwatch, it lacks some features that are either missing or less accurate on other models. The Charge 3 has the longest battery life of any fitness tracker that we’ve tested (up to 7 days), and that’s helped by its low-battery warning.

The Charge 3 is comfortable to wear all day long, and its touchscreen is responsive, but we’d love it if the Charge 3 provided an estimate of battery level when you first put it on. You can see our full guide to the best smartwatches here.

How to use a fitness tracker like the Fitbit Charge 3

We picked the Fitbit Charge 3 because it was the best smartwatch for fitness. It runs Fitbit OS, a custom version of the Android operating system built specifically to run on wearables. It’s the only watch in our guide that has heart rate monitoring.

Fitbit OS has more than 20 apps and can share data directly to third-party services including Runkeeper and Strava. It has a decent app library, especially considering it was designed to work on a fitness tracker. Most importantly, it tracks sleep and heart rate, two vital stats that can impact overall health and wellness.

But it’s still not as comprehensive as Apple Watch Series 2 and comes close to being as polished as the Apple Watch. The Charge 3 is the best smartwatch for fitness that you can buy.

Why You Should Buy This Smartwatch

The Charge 3 is our pick for the best smartwatch because of its combination of great fitness tracking capabilities, sleek design, and excellent battery life. Its screen is the largest we’ve tested at 1. inch, and the watch connects to your iPhone over Bluetooth to provide notifications of incoming calls, texts, and emails.

We’ve found that, even with the screen off, you can usually still see the time and your calendar, and pressing the side button lets you scroll through your apps and home screens.

This watch is perfect if you’re looking for a smartwatch that tracks your heart rate while you exercise, but its major drawback is the fact that it only lasts seven days on a single charge. This is due to You Should Buy This Smartwatch

How to Choose the Right Watch

While fitness trackers like Fitbit have been around since the early 2000s, their popularity has exploded in recent years thanks to wearables becoming mainstream. These days, there are thousands of different brands and models available to purchase online.

Some fitness trackers cost a few hundred dollars while others start around $50. Most of them track steps, distance, and calories. Some can monitor your sleep quality, let you monitor your heart rate, or even measure your stress levels.

When we say “the best,” it means something very specific: It’s the best for the value you’re looking for, the size, the style, the price, and the features that matter most.
