Apple's AI Health Coach to Revolutionize Diet, Sleep, and Mood.

Apple is reportedly developing an AI-powered health coaching service codenamed "Quartz" that will use data from Apple Watch users to monitor sleep patterns, exercise routines, diet, and emotions, then suggest personalized healthy changes based on the AI's analysis. The coaching tool is set to be rolled out next year if development is completed on time, with an emotion log feature and an unknown aid for nearsightedness to debut later this year. Apple is also working to develop the ability to monitor blood pressure and glucose levels directly through the devices.
