Disclaimer
Estimates, not medical advice — please read this one.
Health warning, stated plainly. The TDEE and calorie deficit calculators apply published population formulas to the numbers you type. Individual metabolisms, medical conditions, and medications make real needs different from any formula. Consult a qualified healthcare professional before starting any calorie deficit — especially one aggressive, extended, or if you have any medical condition, take medication, or have any history of disordered eating.
Eating disorders matter here. Calorie tracking is a tool that some people use harmfully. If tracking feels compulsive or distressing, stop and talk to a professional. No app comparison is worth your health.
App facts. Features, free-tier limits and prices are public-listing data checked October 18, 2026, hedged, and refreshed periodically. Pricing especially moves — the apps' own pages are authoritative.
Independence. No affiliate links, no paid placements, no app maker has seen a verdict before you did.
