Frequently asked questions
Is this address monitored regularly?
Yes — every message that comes through the form or the email address is read by our team, typically within a couple of business days.
Can I request a calculator that doesn't exist yet?
Absolutely — select "Request a new calculator" above and describe what you need. Many of our tools started as reader requests.
What should I include in a bug report?
The calculator name, the values you entered, and what result you expected versus what you got. That's usually enough for us to reproduce and fix it.
