Design

For those who thought Fitbit charge 4 was the same as its predecessor, but they are very wrong about this. This new Fitbit charge 4 although looks identical but has the addition of exciting new features. These features are the inclusion of a built–in GPS, which will make this watch just like those running watches that have the whole tracking data stored. Similarly, it has Spotify support and even the special edition Fitbit pay app. Basically what this Fitbit charge 4 does is it has removed the need of carrying your phone to walk or while running. With some pretty colors i.e. black, granite and rosewood it will look sleek with your outfit. Read More
