Fitbit's New Activity Tracker Is Designed to Help You to Get Moving

Although Fitbit had to cancel its launch event due to the Covid-19 pandemic, this is actually the ideal time to launch a new fitness wearable.

The launch also coincides with Fitbit's decision to extend its free trial of Fitbit Premium to 90 days. The company did not share a more specific timeframe. The Charge 4 will be more widely available online starting April 13, as well as in retail stores, if they are open.

What the Fitbit Charge 4 doesn't bring with it is any evidence of the US$2.1 billion buyout by Google that was announced last November - there's no change in the styling of the hardware design or any move towards an integration with Google Fit or Wear OS.

Before we talk pricing and availability for the Charge 4, there's some Fitbit Premium news we need to mention.

Although we already know pretty much everything there is to know about the impending Fitbit Charge 4, it remains unclear when the company intends to release the first member of this hugely successful family of activity trackers with built-in Global Positioning System functionality. Together with Fitbit Pay, this allows you to enjoy the great outdoors without being saddled by a cumbersome phone.

But for the most part this is a device for tracking your movement while walking, running, swimming, cycling, or performing around 20 other types of exercise.

The Charge 3 wasn't the most exciting wearable Fitbit's ever released, but for everything it did, it did exceptionally well. However, while its screen is bright and easy to navigate, it isn't the color display we'd hoped for.

Fitbit says that the Charge 4 should last up to 7 days in normal fitness-tracking mode - the same as the Charge 3, and fairly standard for most fitness trackers - and will last up to 5 hours if you're actively using Global Positioning System. Fitbit Charge 4 is a sleek, swimproof tracker with built-in GPS, Active Zone Minutes, and sleep tracking. Your goal is to spend 150 minutes in each heart rate zone (fat burn, and cardio and peak combined) during the course of a week.

Add to that all of the other features already in the Charge 3 - a heart rate monitor, female health-tracking, contactless payment - and the Fitbit Charge 4, which starts at $149, looks to be a contender as the best fitness tracker overall. Other standout features include an estimated seven day battery life, Spotify connectivity, Fitbit pay as a standard feature (previously available only on Premium editions), and exhaustive sleep tracking, including a relative SpO2 sensor to estimate oxygen level variability.

It's not a medical diagnostic tool, but could be helpful for helping you identify problems that are leading to poor sleep.

GPS: The most notable new feature of the Fitbit Charge 4 is its built-in GPS.

Enter a time when you'd like to be awake, and smart wake will use machine learning to rouse you at the optimum point in your sleep cycle so you don't get up feeling groggy.
