The FitBug Orb is great for runners and other athletes. I think that the FitBug Orb is is perfect for athletes because it is the size of a button and it tracks the number of steps that you take, how many calories you burned, and the distance that traveled. Also, it is one of the cheapest fitness trackers we’ve seen. I think that the cost would be 45 dollars. To make it, it could cost about 115 dollars.
