Snack: Calorie & Macro Tracker
Adjusts to each day's activity
Free · In‑App Purchases
The net calorie tracker that knows what kind of day you actually had.
Take a photo of your plate and Snack works out what's on it. On iPhones with Apple Intelligence running iOS 27, it names each item and estimates the numbers. Fix anything that looks off, then log it. Rather type? Describe the meal in a sentence. It won't be perfect. It'll be better than the number you were about to make up.
Reads your Apple Watch. Adjusts today's calories. Snack reads the active calories you actually burned and builds today's net calorie target around them, so the long lift and the rest day get different numbers, because they're different days. The target is right for the day you actually had.
Snack tracks the four numbers — calories, protein, carbs, and fat — and nothing else. No fiber to hunt down, no sugar to feel bad about, no fourteen fields per meal. Few enough that your first day makes sense, complete enough that your hundredth still does.
Log the easy way too: scan a barcode, or search a database of millions of foods and add several at once. No barcode? Photograph the nutrition label and Snack reads the numbers for you — with Apple Intelligence, it works out which product it is. Log something once and it's there next time.
Ask Siri "How many calories do I have left in Snack" and get today's eaten, burned and remaining without opening the app.
Your health data stays yours. Weight, calories, steps, workouts — Snack reads them from Apple Health and syncs through your own private iCloud, not our servers. There's no account for anyone to break into, because there are no accounts. Photos of your meals are read by Apple's Private Cloud Compute and never stored.
One subscription, one week free. No free-versus-premium maze, no ads, no upsells. Cancel any time from Settings.
The ledger states the facts and stops. What you do with them is your call.

Ratings & Reviews
Snack is made for iPhone Duo.
Folded, it’s the Snack you know. Open it up and Snack opens up with it, with more of your day on one screen. Prop it up like a laptop and Snack works around the fold, so nothing lands in the crease. Your widgets come along too.
