In today's day and age it is hard to keep with all the pressures modern life sets upon us, as rapid advancement of technology and fast paced lifestyle sometimes don't allow us enough time to focus on other aspects, such as health and well being. Realizing this, the world's leading tech brands have put in a lot of effort during the last few years to create a wide selection of fitness trackers that would help you track your activity effortlessly and maintain a healthy and vigorous lifestyle.

However, it gets as difficult as it can be when it comes to deciding which one to buy, since there are more then 30 fitness trackers now available from vendors like Garmin, Sony etc.. after reviewing most of them we can easily vouch for Fitbit which is the only vendor dedicated solely to developing fitness trackers unlike its competitors dealing with far too many products which clearly puts them as general vendor looking to make money only developing anything they could where as Fitbit is the only vendor dedicated solely to manufacturer and researching fitness trackers.

In this list, we compare the best among the best.

Though the Fitbit Charge 2 can receive notifications, you cant reply to them or review them, since it is not a smartwatch.

Compared to its predecessors, Fitbit Charge 2 has around the same battery life, which is around 5 days(depending on the use), but the battery powers a significantly bigger screen.
