The Fitbit Charge 4 fitness tracker builds on its predecessors with the addition of standalone GPS, Spotify support, more sleep tools, and Fitbit Pay.

Built-in GPS; Robust companion app; Spotify support; More sleep tools; Fitbit Pay available on all models (not just Special Edition); Motivating Active Zone Minutes metric; Stylish design

Lacks a color display; Screen wake can be finicky; Basic interface

My first wearable products were bands, the Microsoft Band and Jawbone UP trackers, but over the past few years I've moved on to using watches. Bands are generally designed for daily activity tracking while watches tend to be more powerful.

Lightweight and comfortable for 24 hour wear; Integrated GPS; Detailed sleep and heart rate data; Fitbit ecosystem well supported; Fitbit Pay support

Limited battery life when using GPS; Display tough to see in some conditions

The Charge 4 will be even better when we can leave our homes again

Finally has built-in GPS; Active Zone Minutes better for personal fitness; On-wrist Spotify controls

Small display makes smart features hard to use; Recycled design; Battery life

We finally get built-in GPS! NFC payments standard on all Charge 4s; Active Zone Minutes and heat maps are great additions.

Easy to use; Great battery life; Solid tracking; Free 40 day subscription to Fitbit Premium

No local music playback; Music controls only works with Spotify Premium

I can’t help but wish the Charge 4 was $125 instead of $150—especially since the Versa Lite is just $160—but if you’re patient, you’ll be able to get at or near that price soon enough. If you can get it on sale, that’s just a bonus.

Top-notch fitness; health; and sleep tracking; Excellent battery life; even with GPS switched on; Standard GPS and NFC add value

Plastic body is a downgrade from the metal Charge 3; No third party apps or music storage

Overall, the Fitbit Charge 4 may actually be the best activity tracker they’ve made in a long while. In recent years it seemed like Fitbit had lost their way a bit. This primarily occurred while they focused on slightly higher-end Versa and Ionic units, which struggled to compete in appeal-factor...

The Fitbit Charge 4 isn't flashy or classy, but it does what it's supposed to and looks good doing it.

Still the best fitness tracking band for the active person, the Fitbit Charge 4 adds accurate GPS tracking to its roster of good heart rate insights, best-in-class sleep tracking and Active Zone Minutes. With this mix of features, it’s now pretty unique on the fitness tracker market.
