MacroFactor is a macro tracker, calorie counter, and nutrition coach app that helps you reach your diet goals to lose weight, gain muscle, or maintain with empowering, sustainable results, by combining innovative coaching algorithms with proven nutrition and behavioral science. KEY CAPABILITIES • Adaptive nutrition coach: smart algorithms personalize your calorie and macro intake targets, just like a nutrition coach would, and weekly check-ins keep you on track • Best-in-class expenditure estimate (TDEE): calculates how many calories you actually burn from your own logs and weight data, so your plan fits your body instead of a generic formula • Fastest macro tracker on the market: log food by AI photo, meal description, speech-to-text, barcode scanner, or nutrition label scanner, so logging takes seconds • Verified food database: more than 1.36 million entries, so you can trust the calorie and macro information of the food you log • Food and meal tracker: covers macros and micronutrients with detailed breakdowns for every meal and day, so you see exactly what you eat • Weight Trend: cuts through the noise of daily weight fluctuations, so you see your real progress • Flexible plans: choose Coached, Collaborative, or Manual mode with balanced, low-carb, keto, or carb-focused diets and different macros on different days, so your plan fits your health and fitness goal • Extra tools in one app: period tracker, habit tracker, data insights and visualization, integrations, and dark mode. HOW IT WORKS 1. Set your goal (lose, maintain, or gain) and choose your rate of weight change to set your calorie deficit or surplus. 2. Log your meals in the food log and weigh in with the weight tracker as usual. 3. Each week, MacroFactor compares your calorie and macro intake with your weight trend to calculate your true energy expenditure (TDEE) and detect changes in your metabolism. 4. It then adjusts your calorie, protein, and macro targets for the week ahead, so your diet plan keeps working and you avoid a plateau. FAQ • How does MacroFactor set my calorie target? It estimates your energy expenditure from your food logs and weight trend, then adjusts your targets at each weekly check-in. • What if I go over my targets or skip logging? Nothing breaks. The algorithm is adherence neutral, so your check-in and calorie adjustment still work, with no warnings or red numbers. • Can I set my own macros instead of following the coach? Yes. Choose Manual mode, and set different macros for different days. • How can I log food quickly? Snap a photo with AI food logging, describe your meal, speak it, or scan a barcode or nutrition label.
