Delta vs Dynamic TDEE Tracker

Delta tracks your weight and calorie intake and calculates your real TDEE — not a formula estimate, your actual one. 10 days free. One payment for unlimited access. No subscription. Most apps give you a TDEE based on height, weight, age, and activity level. That number is a population average applied to you. It's a starting point, not a measurement. Delta starts there too, but transitions away from it as you log real data. By day 10 your estimate is derived entirely from what you actually eat and how your weight actually moves. The longer you log, the more accurate it gets. Log your weight each morning and your calorie intake each day. Delta averages the last 10 days to filter out noise from water retention and normal fluctuation. It combines your intake with observed weight change to estimate your true maintenance calories, then smooths that estimate over 28 days to avoid overreacting to short-term variance. The result is a daily calorie target adjusted for your goal — cut, maintain, or bulk — grounded in your data rather than population averages. Key features: Daily weight and calorie logging Adaptive TDEE that transitions from formula to fully empirical as you log 28-day smoothing for a stable, actionable number Goal-based calorie targets for cut, maintain, or bulk Apple Health integration — weight and TDEE baseline written automatically Daily reminders for weigh-in and calorie logging Why Delta? Δ is the symbol for change. Your weight change and calorie balance are what actually determine your TDEE. Delta measures both and gives you a number that reflects your reality, not someone else's average.

This app calculates your real, personalized Total Daily Energy Expenditure using your actual calorie intake and weight trend over the last 12 weeks — not rough estimates from height, weight, and activity labels.
