Macrology: Calorie Tracker

Macrology is a precision calorie and macro tracker for anyone who wants real accuracy, not just a rough estimate, whether that means pointing your camera at a plate or weighing food on a kitchen scale.

AI-POWERED LOGGING
Snap a photo of your meal or type a quick description, and Macrology estimates the calories and macros for you. Add a note for extra accuracy ("large portion", "no dressing") and refine the result before you log it. Get 3 free AI estimates to try it out, with a free account.

PRECISION, DOWN TO THE GRAM
Prefer exact numbers? Search a food and log it by weight or by count ("2 eggs" instead of guessing grams). Every food remembers how you usually log it, so repeat meals take one tap.

BUILT-IN FOOD DATABASE
Search thousands of whole foods and packaged products, sourced from a national food composition database and Open Food Facts, or add your own custom foods and recipes. Save meals you eat often as templates for one-tap logging.

TRACK WHAT MATTERS TO YOU

Calories, protein, carbs, fat and fibre
Key vitamins and minerals
Supplements, tracked separately from food
Body weight, with a trend chart and a projection based on your logged calories

YOUR UNITS, YOUR LANGUAGE
Switch between kilograms and pounds, centimetres and feet/inches, grams and ounces, calories and kilojoules. Macrology adapts to how you actually measure things, wherever you are.

PRIVATE BY DEFAULT
Everything you log stays on your device. No account is required to use the app. Sign in with Google only if you want your data backed up and synced across devices.

FREE TO USE
Macrology is free forever for local, on-device tracking. A Pro subscription unlocks unrestricted AI estimates, adaptive coaching that adjusts your targets from real results, and a 30-day nutrient report.

Built for anyone who's tired of nutrition apps that guess. Log it exactly, or let AI do the guessing for you.
