Distinction Between Fitness Tracker and Smart Watch

Is there really a difference? Yes, while the two – a fitness tracker and a smartwatch – tend to overlap, they each have their intended purpose.

The fitness tracker is primarily designed to keep track of your health and exercise. However, some more advanced trackers can also display texts and app notifications on your wrist like a smartwatch, but their intended purpose is to focus on your health and daily activity monitoring. They will generally also have a digital watch function.

A smartwatch not only keeps track of your health and exercise but also keeps you connected by delivering notifications and updates on your wrist. You can find our detailed guide to tween smartwatches over here.


In a quest to find your tweens a fitness watch, I hope you have finally found one in the above compilation. These watches have great features and functions that will help your tween get the best out of their activities.
