About GetFit Matics
GetFit Matics was built with a single mission: to give everyone access to free, science-backed fitness tools that actually work — without paywalls, without account requirements, and without misleading claims.
We believe that accurate health information should be available to everyone, regardless of whether they can afford a personal trainer or dietitian. Our calculators use the same peer-reviewed formulas trusted by sports scientists and healthcare professionals worldwide.
Our Commitment
Our Story
GetFit Matics was founded by a team of fitness enthusiasts and web developers frustrated by fitness calculator sites that were cluttered with ads, required email sign-ups, used outdated formulas, or provided results with zero context or explanation.
We set out to build the resource we wish had existed — a clean, fast, comprehensive platform where you can calculate your BMI, TDEE, macros, body fat, 1RM, and more, with full explanations of how the formulas work, what the results mean, and what to do next.
