IBM brings Watson AI to Apple Watch with SleepHealth app

IBM has announced a new app for iPhone and Apple Watch that aims to gather data on the relationship between sleep habits and overall health. Dubbed SleepHealth, the app does far more than reveal when users are waking up in the night like typical sleep trackers. The app is built on IBM's Watson Health Cloud, a platform that was developed in partnership with Apple and Johnson & Johnson, and connects with ResearchKit, the open-source framework from Apple.
