Much attention has been paid to wearable technology, ranging from watches, pendants, or clip-ons. This past holiday season Fitbit’s app was no. 1 in downloads on Apple’s app store, a strong indicator of sales of the hardware. For the 3rd quarter of 2015, Fitbit sold 4.8 million devices according to RBC Capital Markets, holding a 22% market share. Misfit Wearables, a maker of wearable activity trackers, was recently acquired by Fossil Group, a watch manufacturer, for $260 million, further demonstrating the interest in this space.
