Nibble - Calorie Tracker

Track what you eat the way you take notes. Type it, Nibble estimates the rest. All on your phone. Nothing leaves your device.

Nibble is a calorie and nutrition tracker that works like a notes app. Type what you ate in plain language — "half a bowl of oatmeal", "2 eggs with toast", "coffee with milk" — and Nibble figures out the calories instantly. No barcode scanning. No searching through databases. No logging into anything. Just type and move on with your day.

The magic is on-device AI. Nibble uses Apple's built-in intelligence to understand your food descriptions and estimate calories and macronutrients — protein, carbs, fat, fiber, and sugar — right on your iPhone. Your food data never leaves your device. There are no accounts, no servers, no cloud syncing. What you eat stays between you and your phone.

SIMPLE DAILY LOGGING Open the app, type what you had, and press return. That's it. Your running calorie total updates at the top. Each meal is one line — clean, minimal, no clutter. Delete an entry with a swipe if you made a mistake.

CALENDAR VIEW See your history at a glance. Every day on the calendar is color-coded — green when you're on track, red when you go over. Tap any day to see exactly what you ate. Add entries to past days if you forgot to log something.

REPORTS THAT MAKE SENSE Weekly and monthly charts show your patterns without making you do the math. See your average intake, your highest and lowest days, which foods you eat most, and whether you're trending up or down. Export everything as a CSV if you want your raw data.

APPLE HEALTH Nibble writes your calorie and nutrition data to Apple Health so it fits into your broader health picture alongside workouts, steps, and sleep. Completely optional — works perfectly without it.

FULL NUTRITION, SAME SIMPLICITY Nibble doesn't just count calories. Tap any entry to see a complete nutritional breakdown — protein, carbs, fat, fiber, sugar — estimated automatically from your description. Set daily macro goals and track your progress. If an estimate looks off, tap to correct it. Your edits are preserved even if you rename the food later.

PRIVATE BY DESIGN No account required. No data collection. No analytics. No ads. Nibble runs entirely on your device using Apple's on-device AI. Your food diary is stored locally and nowhere else. Period.

Nibble is for people who want to be more aware of what they eat without turning every meal into a data entry chore. If you've tried calorie trackers before and stopped because they were too tedious, Nibble might be the one that sticks.
