Apple Watch's New AI Day Summary Tracks These Activities

Leaker "pdfu" today shared additional code-level details about the Apple Watch Series 12 and Ultra 4's new day summary feature, offering a clearer picture of what the AI tool will actually track. In a new post on X, pdfu said that the summaries generated by the feature, referred to in code as "Ambient Sensing," include fields for time and date, location, meal information, and the people present along with their relationship to the user. The leaker also listed dozens of activity categories the underlying code supports, covering everything from meal prep and household chores to workouts, commuting, shopping, and screen time, alongside a catch-all "Unknown" category. The full list of activity categories is as follows: Eating Meal Snacking Preparing Meal Making Drinks Baking Plating Vacuuming Taking Out Trash Washing Dishes Loading Laundry Folding Laundry Mowing Lawn Watering Plants Gardening Mopping Dusting Cleaning Walking Running Cycling Strength Training Yoga Elliptical HIIT Cardio Hiking Regular Commute Driving Flying Riding Train Riding Bus Grocery Shopping Clothes Shopping Home Goods Shopping Hardware Shopping Taking Break Waiting Relaxing Social Dining Meeting Partying Gathering Family Time Brushing Teeth Flossing Getting Dressed Applying Lotions Watching TV Using Tablet Using Laptop Using Desktop Reading E-Reader Using ATM Attending Class Attending Sermon Attending Keynote Reading Book Doing Homework Taking Notes Working Drinking Unknown The post builds on a report from Bloomberg's Mark Gurman, who said the Apple Watch Series 12 and Ultra 4 would ship with a feature that analyzes a user's day, including conversations they've had, and provides a summary of what took place. Gurman noted the system apparently does not record or store audio and cannot produce a transcript to preserve privacy, and it is unclear how exactly it works.
