Free health & calorie tools

Everything you need to set a target, train smarter, and log meals without a food database.

High-intent calculators bring people in; the photo tracker turns curiosity into a daily habit — and habits are what convert to subscriptions. Pick a tool below.

Frequently asked questions

Which tool should I use first?

Start with BMI for a quick screen, then TDEE for a calorie target, then scan meals with the photo tracker so the plan matches real food.

Are these calculators free?

Yes. BMI, TDEE, exercise burn, and guides are free. Photo scans include a free weekly allowance; paid plans add more scans.

Do I need an account?

Not for calculators. An account saves goals, weight, and meal history so you can stay consistent.
