The Beddit Sleep Tracker uses a sensor about the same size and thickness as a piece of duct tape to measure total sleep time, resting heart rate, respiration rate, how long it took you to fall asleep, how many times you got up, and the amount of deep sleep achieved. The companion Android and iOS app then offers detailed postsleep analysis and feedback meant to help improve sleep.
The acquisition could help beef up the health- and wellness-tracking ambitions Apple has for the Apple Watch as it takes on Fitbit, a leader in the fitness-tracking market. The Apple Watch already has the requisite heart rate sensor built in but now needs the software and hardware to do more than just measure and track heart rate.
There's certainly a market for sleep tracking. The Centers for Disease Control and Prevention estimates that there are 50 million to 70 million adults in the US who suffer from a sleep or wakefulness disorder such as sleep apnea.
Financial terms of the acquisition weren't released. Apple didn't immediately respond to a request for comment.
