September 15, 2026
Photograph your plate. On iPhones with Apple Intelligence running iOS 27, take a photo of your meal and Snack names what's on it and estimates each item. Fix anything that looks off, then log it. Photos are read by Apple's Private Cloud Compute and never stored. No barcode? Scan the label. Snack works out which product it is, checks it against the food databases, and shows you the numbers before you log. Ask Siri. "How many calories do I have left in Snack" answers with today's eaten, burned and remaining. Spotlight finds your recent days too. Add several foods at once. Tap Select in search results, tick what you ate, and add them together.

FAQ
How does Snack adjust daily calorie targets?
Snack reads your active calories burned from your Apple Watch and subtracts them from your daily budget. This means your calorie target increases as you move throughout the day, providing a more accurate budget for your specific activity level.
What macronutrients does Snack track?
Snack tracks the four main macronutrients: calories, protein, carbohydrates, and fat. It focuses on these core metrics without overwhelming users with less critical nutritional details.
Is my health data private with Snack?
Yes, your health data, including weight, calories, steps, and workouts, never leaves your phone. Snack reads data from Apple Health and syncs through your private iCloud, with no servers to be breached.
How can I log food if I don't know the exact details?
Snack offers an AI-powered feature where you can describe your meal in a sentence, and the app will estimate the nutritional numbers. While not perfect, it's designed to be more accurate than guessing.
