I compared 3 paid TDEE calculators against a free one

I spent an afternoon researching TDEE calculators. Here is what I found:

MacroFactor: $71.99/year. And you need to log every meal for 3 weeks before it gives you a TDEE.

MyFitnessPal Premium: $79.99/year. TDEE is buried in settings.

Cronometer Gold: $59.99/year. Single formula, no Katch-McArdle.

FreeTDEE (freetdee.com): Free. Instant. 6+ formulas. No account.

The math is the same

All use the same equations: Mifflin-St Jeor, Harris-Benedict, Katch-McArdle. The formulas are public.

I built FreeTDEE because every calculator either charged money or was buried in an app I did not want.
