Apple has acquired a sleep tracking app and Beddit, a Finnish hardware company that makes sleep-tracking devices that work with apps for iOS and the Apple Watch.
The terms of the deal were not disclosed.
Beddit manufactures Beddit 3 Sleep Monitor, a monitoring device which tracks heart rate, breathing and sleep time when placed on a bed. The monitor sells for $149.95 in Apple's online store and transfers the data to Beddit's iPhone app for analysis.
The Apple Watch is a device that requires daily charging, usually at night.
As such, the device doesn't offer any native sleep-tracking capabilities, though there are some third-party apps that work for people who can find time to charge their watches during the day.
