activity tracking wearables
Some 21 percent of US adults use a wearable device right now, and of those, 36 percent use a Fitbit device, according to a Forrester Research survey of 952 online US adults.
In February Fitbit announced a voluntary recall of its newest activity tracking device, the Fitbit Force, after a number of users complained of skin irritation from the wristworn device.
Misfit Wearables, the company behind the Misfit Shine activity tracker, has upped its sleep tracking game, entering into a partnership with Beddit, the Helsinki, Finland-based mattress sensor startup.
In the first quarter of 2014, Fitbit held the majority of the market share, according to a report from Canalys.
