EVIDENCE-BASED METABOLIC TRACKING
Find Your Real
Maintenance Calories
Most calculators estimate your burn with a generic formula. Calculate your baseline instantly below, or track your real-world adaptive expenditure over time.

HOW IT WORKS
Tracking that actually works.
Log Scale Weight
Step on the scale each morning. Water fluctuations are normal; our algorithm smooths them out.
Log Daily Calories
Log what you eat. Consistent averages are far more valuable than perfect daily tracking.
Get Your True TDEE
The feedback loop calculates your exact expenditure, updating your targets automatically.
ADAPTIVE METABOLIC ENGINE
Beyond simple calculators.
Basic online tools rely on static 1990s estimates. Our multi-variable feedback system continuously aligns your target intake with actual bodyweight trends.
Water Weight Noise Filtering
Filters out daily sodium and hydration spikes to reveal true fat loss
Real Energy Balance Calculation
Compares what you eat against your actual rate of weight change
Confidence & Consistency Weighting
Your calculation becomes more precise as you log more days
PRECISION BY DESIGN
Engineered for consistency.
Every feature is focused on giving you an accurate, noise-free metabolic feedback loop.
Dual-Filter Metabolic Engine
Exponential moving average algorithms dampen daily water, sodium, and glycogen fluctuations to reveal your true underlying expenditure.
Dynamic Goal Planning & ETA
Set your desired rate of weight loss, gain, or maintenance. Calorie budgets and target milestone dates adjust continuously as your TDEE shifts.
Weight-Adjusted Formula Curve
Unlike static 1-time calculators, our baseline dynamically recalculates with your rolling weight to accurately measure metabolic adaptation.
1-Click CSV Import & Export
Seamlessly migrate your history from MyFitnessPal, MacroFactor, Cronometer, or Excel spreadsheets with zero data lock-in.

REVIEWS & PROOF
Backed by math. Loved by real users.
See how lifters, athletes, and data-driven trackers replaced generic online formulas with true adaptive metabolic feedback.
Marcus Vance
Natural Bodybuilder & Coach
"Online calculators told me my maintenance was 2,300 kcal. I was starving and stuck. This app's adaptive feedback algorithm revealed my actual TDEE was 2,750 kcal. Game changer for prep."
Elena Rostova
Powerlifter
"The water weight filtering is incredible. Normal daily fluctuations used to throw off my entire diet. The system dampens noise so I actually know when body mass is shifting versus holding water."
David Chen
Software Engineer & Runner
"As a data nerd, I love the math rigor behind this. Seeing the smooth trend curve react dynamically to my mileage and food logs eliminated all guesswork from my lean bulk."
Sarah Jenkins
CrossFit Athlete
"I used to constantly under-eat because standard formulas undercount high activity. AdapTDEE adjusted to my training volume within 3 weeks. Essential tool."
