Fitbit has officially announced the Charge 4, the new successor to one of their most popular wearable, the Charge 3. The Charge 4 isn’t so outstanding in design and otherwise despite the acquisition by Google which many of us believed will usher in better design and all, but it comes with few upgrades like inbuilt GPS and music control which sets it apart from it’s predecessor. In this post, we look at the difference between the Fitbit Charge 3 vs 4.
