About this app

Macrology is a calorie counter and macro tracker for two kinds of logging: point your camera at a plate for a fast AI estimate, or weigh your food and log it to the gram. Use whichever suits the meal.

SNAP A PHOTO, GET THE MACROS
Take a photo of your meal, or describe it in a few words, and Macrology estimates the calories, protein, carbs and fat of every item on the plate. Add a note for accuracy ("large portion", "no dressing"), fix any item in a tap, then log the whole meal as one. Scan a barcode for packaged food, or the nutrition label itself. A free account includes 3 AI estimates to try it.

OR LOG IT TO THE GRAM
Search thousands of foods from the Australian Food Composition Database (Food Standards Australia New Zealand) and Open Food Facts, then log by weight or by count ("2 eggs"). Every food remembers how you usually log it, and common serving sizes are one tap away.

LOGGING THAT GETS FASTER
Same as yesterday: an empty meal offers the last time you ate it, in one tap.
Copy or move any items to another day or meal.
Save meals you eat often and log them again in one tap.
Suggestions learn what you eat at breakfast, lunch and dinner.
Custom foods and recipes for anything homemade.

SEE WHAT'S WORKING
A weight chart that smooths daily ups and downs into your real trend, with your goal and a plain estimate of when you'll reach it.
Calories, protein, carbs, fat and fibre, plus key vitamins and minerals such as iron, calcium, vitamin B12 and folate.
A weekly recap of how the week went.
Progress photos with each weigh-in, kept on your phone.

ON YOUR HOME SCREEN
Home screen widgets show the calories and grams of protein, carbs and fat you have left today, and the wider one adds camera and barcode buttons that open straight to the scanner.

Meal and weigh-in reminders that skip a meal once it's logged.
Supplements, tracked separately from food.
Water intake.
Weight sync from Health Connect, for smart scales.
Kilograms or pounds, grams or ounces, calories or kilojoules.
