Design

Aesthetics are important because it represents your personal image like the one wearing the watch. So, pick a fitness tracker with a design that fits your style, be that minimalist or elegant. 

Battery Life

Battery life is, arguably, one of the most important features you have to look for when buying the best fitness tracker.

The longer the battery life, the better so you can use the awesome features of the watch or use your favorite fitness app longer!

Navigation/ GPS

Your fitness tracker(s) GPS helps the watch determine your exact location. This is important if you are outdoors. The same features in both high-end and cheap fitness trackers also accurately record speed, elevation, and distance during activities, like cycling and running.
