Contact & suggestions
Have a suggestion, want to request a new calculator, or spotted an error in a result? Get in touch — we read every message.
What to write, and what to expect
Not every message needs the same detail. These are the four that arrive most often, and what helps in each case:
- Reporting a wrong result. The most useful message names three things: which calculator, exactly which values you entered, and the result you expected instead. With those three the case can be reproduced straight away; without them the reply is usually another round of questions. A screenshot helps, and so does telling us which browser you used.
- Asking for a new calculator. Tell us the decision you are trying to make, not only the name of the formula. Knowing what you would do with the number shapes which inputs the tool asks for and which reference ranges it shows.
- Suggesting a clearer explanation. If a field label, a unit or a reference range confused you, that is a defect worth fixing. Say where you got stuck — wording problems are far more common than arithmetic ones, and they are the reason a correct number can still be read wrongly.
- Partnership or advertising. Put the specifics in the first message: who you are and what you propose. Anything that would place a health claim in front of readers without a source behind it is declined, whatever it pays.
If you are writing about your own case
This deserves an honest answer up front: we cannot give you a medical opinion. Messages asking whether a blood pressure reading is dangerous, whether a due date is right, or what to do about a cholesterol or blood glucose result will get a reply — but the reply will be the same one: take that number to a doctor, who can see what a calculator cannot. It is not evasiveness. Nobody here is a health professional, and a confident answer from a stranger on the internet would be worth less to you than the silence.
What we can do is explain how a tool reached its number: which formula it used, what it assumes, and where its reference ranges come from. Ask that, and you will get a real answer with the source attached.
Reply times, and what happens to your message
Every message is read. Replies usually take a few business days, and reports of a wrong calculation are handled before anything else. Your email address is used only to answer you: it is never published, never sold and never added to a mailing list. If you would rather not use the form, plain email works just as well — contact@calculatorsfit.com. Please do not send medical records, test results or any other personal health information; nothing in this form is meant to receive it, and we do not need it to fix a calculator.
