This new tool allows individuals to connect their Apple Health data, medical records, and fitness tracking apps directly to ChatGPT for tailored health conversations. It lets you link your personal health data, such as step counts, sleep logs, heart rate readings, and lab results. The feature connects with various data sources, including Apple Health (Apple’s built-in iPhone health dashboard), Function (a preventive health testing service), and MyFitnessPal (a popular calorie and nutrition tracker). For instance, if you’ve logged several nights of poor sleep in Apple Health, ChatGPT can consider that when you inquire about feeling sluggish. If you’re an iPhone user with data in Apple Health from your Apple Watch or other fitness apps, you have a wealth of health history ready to be utilized.
