FitBit Charge 4 Review

When we are talking about Fitbit smartwatches and activity trackers, the first thing that comes to our mind is the two most famous Fitbit models. As you probably know, we are talking about Versa and Charge.
The original Fitbit Charge was announced in October 2014 and released one month later for $130 retail. This tracker has all the necessary features. Some of them were automatic step tracking, sleep tracking, flights of stairs, and an estimate of distance traveled. It is fair to say that the first Fitbit Charge was a decent fitness tracker.
The Charge series has developed since then, and every line was a bit better than the prior one.
Let us see how good is the last fitness tracker from Fitbit in our Fitbit Charge 4 review.


The Fitbit Charge 4 looks the same as the Fitbit Charge 3.This is one thing that we didn’t like about this band. The dimension of this tracker is 9.7 x 1.1 x 0.5 inches, 1.12 ounces. It is available in a few different colors: Forest White, Rosewood Woven, Midnight Woven, Navy Sport, Black Premium Leather, Midnight Blue, Black Sport, Black Classic, and Berry Sport. Charge 4 features very comfortable wristband, it could be worn while you are working out, and also casually. Furthermore, it is equipped with a backlit OLED display that responds to natural swiping and scrolling. By choosing from a variety of clock faces you can personalize your tracker to fit your needs.
No matter how old you are or how hard you love to train, this fitness tracker will be an excellent choice.

You can control your playlists, songs, and podcast directly from your wrist using the Spotify app. Unfortunately, this feature works only if you have your smartphone nearby, which means that you can’t download your playlist direct on Charge 4. Also, the Spotify premium is required, which is not available in all countries.
