Apple acquires sleep-tracking company Beddit

CNBC:

Apple has acquired an app and sleep monitoring device called Beddit. Beddit has updated the privacy policy on its website to state that it has been acquired, although the terms of the deal are not yet clear. The previous page that linked to Beddit's Apple Watch applications appears to have been taken down.

I'd assumed Beddit was a sleep-tracking app like Sleep++, but it's also a connected device you place under your sheets. This allows it to gather a lot more data.

I'm interested in sleep tracking, but so far I've resisted buying a second Apple Watch to wear at night.
