Deficit: Calorie Counter

Most weight loss apps make you guess. Deficit doesn't. Snapping photos of your plate won't tell you how much to eat. Deficit calculates the exact calorie deficit you need to hit your goal weight—based on your stats, your activity, and real biometric data from your wearables. Then it tracks every meal and calorie burned against it. It's not a diet. It's the number you need to hit, and the tools to hit it. HOW DEFICIT WORKS 1. Take the 60-second onboarding quiz. We ask about your weight, your goal, your activity level, and a few other inputs. 2. Get your daily calorie target. Built on real metabolic science—TDEE, BMR, and activity multipliers—not a generic 1,200 calorie guess. 3. Log meals, sync your wearables, and hit the number. Deficit auto-adjusts as your weight changes, so your target always matches your goal. WHAT MAKES DEFICIT DIFFERENT - Real math, not photo gimmicks. We calculate your deficit using validated metabolic formulas. - Adjusts as you progress. Drop 10 lbs and your target updates automatically. - Built on data you already have. Pulls calories burned, heart rate, and recovery from your wearables instead of asking you to guess. - Designed to be measurable. Ever
