About FitMeter
Last reviewed: September 2026
Who we are
FitMeter is a free fitness and nutrition calculator site built for people who want accurate, honest numbers — not an email address. Every calculation runs entirely in your browser. No data leaves your device.
The site was founded with a simple premise: the best fitness calculator is one that shows you its uncertainty, explains its formula, and does not require you to create an account to see the result.
Editorial policy
Every formula on FitMeter is sourced from peer-reviewed research or validated clinical guidelines. We cite our sources on each tool page: the original publication, the validation population, and the known error margin. Where two accepted formulas disagree, we show both and explain the difference rather than silently picking one.
We do not generate content for the purpose of ranking. We publish one indexable URL per tool. We do not create permutation pages because those pages add no information and their sole purpose is search visibility.
Author and credentials
Content on FitMeter is reviewed by editors with backgrounds in exercise science, sports nutrition, and clinical dietetics. Formula implementations are verified against published reference values and unit-tested before publication.
If you identify an error in any formula or output, please contact us at hello@fitmeter.app.
What we are not
FitMeter is not a medical provider. Our calculators are estimates for informational purposes. They are not a substitute for advice from a physician, registered dietitian, or other qualified healthcare professional. See our Medical Disclaimer for full detail.
Privacy
We do not collect, store, or transmit any data you enter into our calculators. Inputs are processed locally in your browser and discarded when you close the tab. We use Google Analytics 4 for aggregate traffic analysis and Google AdSense to serve advertisements. See our Privacy Policy for full detail.
