CalculCalories is a free, French-language site of nutrition calculators. Enter your age, sex, height, weight, activity level and goal (lose, maintain or gain) to estimate your basal metabolism, daily energy expenditure (TDEE), calorie target, protein range and macro split, using the Mifflin–St Jeor formula. Other tools cover BMI, calorie deficit, protein needs and the nutrition of your own recipes, per serving. It also has food pages, sport pages (walking, running, cycling, weight training) and guides. Formulas are published and sources cited (EFSA, ANSES, WHO). No account required; results are estimates, not medical advice.

Useful set of calculators. One thing worth double-checking: whether the TDEE and BMR formulas state which equation they use (Mifflin-St Jeor vs Harris-Benedict), since the two can differ by 5-10% and users often compare results across apps. Also consider showing the activity-multiplier step explicitly - that is where most people lose track of how the final number was reached.
Solid set of calculators - combining calorie, TDEE, BMR and macros in one place saves hopping between tools. Since it's in French, an English toggle or auto-translation would widen the audience a lot; I'd also find it useful if the macro split could adjust for training frequency or dietary preference (keto, high-protein, etc.).
Publishing the formula and citing EFSA, ANSES and WHO is the part I'd point people to; most calculators never say which equation they use. On the sport pages, are exercise calories worked out from MET values? Those can be well off for one particular person, so a line on each page saying which method it uses and how far it can vary would fit the "sources cited" approach nicely.
CalculCalories sounds like a useful resource for anyone looking to better understand their daily calorie needs, energy expenditure, and macronutrient intake. I especially like that it explains the formulas and provides nutrition information without requiring an account. Combining these estimates with balanced meals and regular exercise can help people work toward realistic health goals.
