About Free Tools
A simple collection of beginner-friendly fitness and nutrition calculators designed to make numbers easier to understand.
What this site is for
Free Tools was built to give beginners a simpler way to estimate calories, macros, protein, hydration, and weight planning without needing a complicated app.
The aim is to make common fitness and nutrition numbers feel easier to understand and easier to use.
How the site should be used
The calculators on this site are designed as starting estimates. They are there to help you plan, not to give a perfect answer for every person.
The best way to use the site is to begin with maintenance or TDEE, then move into calorie deficit, macros, protein, and goal planning if those are relevant to you.
What the site is not
This is not a medical service, a diagnosis tool, or a replacement for personal advice from a qualified professional.
It is a simple educational resource built to help users make sense of common health and nutrition calculations.
