Built for people who take fitness seriously

Seven tools that usually live in seven different apps — finally under one roof, talking to each other.

  • Goal-adjusted: lose, maintain, gain

Why this matters

What gets measured, gets improved

Studies show that people who track their food intake lose twice as much weight as those who don't. FarzCalc removes the friction: no spreadsheets, no guesswork, no messy apps.

Accurate targets Your calorie goal is derived from real body data — not a one-size-fits-all number.
Net calorie math We subtract what you burn from what you eat. The number on screen is the one that matters.
Privacy by design Runs locally on your machine. Your food, weight and workout data never leaves your computer.
