Apple's AI Health Coach and Mood Tracker in the Works.

Apple is reportedly developing an AI-powered health coaching service, codenamed Quartz, and tools to track users' emotional health. The service will make suggestions and create programs tailored to users' specific health conditions based on data from an Apple Watch. The coaching service is expected to come with a monthly fee and will likely be rolled out next year. Apple is also expanding its health app to the iPad and adding new tools to track users' emotions and manage vision conditions.
