A free set of health, fitness and nutrition calculators: BMI, body fat, ideal weight, RMR/TDEE, calories, macros, 1RM, running pace and VO2 max. Each one explains the formula step by step and shows the result on a visual gauge — so you understand it, not just read a number. No signup, works right in the browser, in English, Español, Français, Italiano, Deutsch and हिन्दी.









Would love to see a progress tracker that saves my last few entries locally so I can spot trends over time without needing an account. That would make the calculators feel way more useful between sessions.
Love that the visual gauge pairs with the formula breakdown. Most calculators just spit out a number and leave you guessing, so seeing where the math actually comes from is a really thoughtful touch.
Finally a calculator set that actually shows its work instead of just spitting out a number. The gauge view for TDEE made it easy to see where I land.
