While there was no change in the top two spots for the Q3 2015 IDC wearable numbers, Xiaomi made a staggering jump. In terms of market share, Fitbit is still in the top spot with a 22 percent market share and 4.7 million units shipped in the quarter. The company's numbers were padded by the fact that a number employers are giving their workers Fitbit devices, including Target's order of 335,000. Apple remains at number two, where it debuted in Q2. Cupertino shipped 3.9 million units, aided by both the release of WatchOS 2 and its gadgets going on sale in more locales.
