Contact HealthFit

Questions, corrections, and feedback can be sent to hhammoud@inovisum.com. Messages are read by a human; most threads are answered within two to three business days. The site does not use phone or social DM channels for support — written feedback lets us cite the source guideline and ship a fix that another reader can verify.

Please do not send personal health information

HealthFit cannot give individualized medical advice and email is not a secure channel for protected health information. Do not include your weight, lab values, gestational age, menstrual cycle dates, or other personal medical details in a message. If the calculator returned a number you want to discuss, describe it generically (e.g. “the BMI tool returned a value that disagreed with my doctor’s reading”) without sending the underlying figures.

Reporting a calculation issue

For a calculation correction, please include the tool name (e.g. BMR Calculator or Due Date Calculator), the formula version you expected (Mifflin-St Jeor vs. Harris-Benedict, LMP vs. conception date, Karvonen vs. Tanaka), and the authoritative source you are comparing against. With those details, the page can be re-checked against the cited guideline and updated quickly.

Categories

Bug reports: a calculator returning a number that disagrees with a documented source. Tool requests: a single-purpose health or fitness calculator you would like to see. Privacy and data: questions about analytics, advertising, or how sensitive inputs are handled. Editorial: a clinical guideline that has changed since our last review.

Commitments

We read every message. We will not add you to a mailing list, share your email, or follow up with marketing. We will not give individualized medical advice — those questions must go to a licensed clinician. We will fix a guideline citation or a math error promptly once it is reproducible.
