Find your calorie zone.
Tell Calzone about yourself and pick a goal. It works out how many calories to eat each day, with your deficit built in. Then log your food in seconds and watch the day add up.
For iPhone. No diet rules, just your number.
-
Your deficit, calculated
Calzone works out your BMR and TDEE from your height, weight, age, sex and activity level, with the Mifflin-St Jeor equation. Lose or gain 1 or 2 lb a week (0.5 or 1 kg), or maintain, and it turns that goal into a daily calorie target.
-
Fast food logging
Scan a barcode, or scan a Nutrition Facts panel and Calzone reads it right on your iPhone. Search a food database built on USDA FoodData Central, save your own foods, and build recipes to log by the serving.
-
More than calories
See protein, carbs and fat for every meal and every day, plus 30+ nutrients, including fiber, sodium, added sugar, cholesterol, vitamins and minerals.
