Dieting is not just about calories but also about the kinds of calories you eat. Our clear easy-to-use interface makes it easy to ensure you are getting the right proportion of macronutrients - carbs, protein and fats to match your diet. The step-by-step setup process will work out your calorie requirements and nutrient ratios based on your diet and weight loss goal. Preset nutrient ratios for many common diets are included as well as support for 5:2 fasting days. New foods can be entered in seconds using our custom keypad which has built-in unit support and the ability to enter simple calculations and fractions. Lookup foods by barcode using OpenFoodFacts, recall recently eaten foods, or search the built-in USDA fresh food database containing thousands of common food items - all from within the food entry screen. Fully supports the Apple Health app. The calories and nutrient values of the foods you eat are synced to the Health app and your daily calorie target is automatically adjusted as your weight changes.
