The net calorie tracker that knows what kind of day you actually had. 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. It pulls active burn from your Apple Watch and subtracts it, so the budget grows as you move — 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. Your health data never leaves your phone. Weight, calories, steps, workouts — Snack reads them from Apple Health on the device and syncs through your own private iCloud, not our servers. There's no account for anyone to break into, because there are no accounts. Ate at a barbecue and have no idea what was on the plate? Describe it in a sentence and Snack estimates the numbers, right on the device. It won't be perfect. It'll be better than the number you were about to make up. Log the easy way too: scan a barcode, point your camera at a nutrition label, or search a database of millions of foods. Log something once and it's there next time. 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.
