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.

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

The Fitbit Charge 4 looks almost identical to its predecessor, including the grayscale touchscreen, but the addition of built-in GPS makes a huge difference, and helps make it a viable alternative to fully-fledged running watches if you enjoy working out for fun and health, but don't need a torrent of data on splits, cadence and elevation.

The Fitbit Charge 4 boasts some great features, especially personalised Active Zone Minutes - a motivational fitness metric to aim for. It’s our new favourite all-round Fitbit tracker, bests the Versa 2 smartwatch with its built-in GPS, and even matches the Versa 3 in many ways.

The Fitbit Charge 4 is well worth the $150 price tag, it is a premium fitness tracker that packs many features into a beautiful package. The embedded GPS introduces wonderful opportunities for standalone use, though it needs some polishing.

Onwards and upwards, as the motto goes for any tech product, the Fitbit Charge 4 is the latest evolution of a Fitbit classic. The original launched back in 2014, and has evolved quite a bit over the last 6 years.

For many people, Fitbit is synonymous with fitness trackers, but the company has faced new challenges from smartwatches in recent years. The Fitbit Charge 4 signifies a change, even if it doesn't look too different from its predecessor.

Display While the necessity of a colored interface on a fitness band is debatable; competitors like the Garmin vívosport and the Xiaomi Mi Band 4 reach similar battery life with colored OLED displays and lower prices.

The Fitbit Charge 4 is the best fitness tracker you can buy, period. Fitbit didn't need to do much to achieve this title again, but it managed to fix all our gripes with the Charge 3 and keep it at the same price point. The built-in GPS is welcome, as is Fitbit Pay being standard across all models.
