• Found a mistake? Include the calculator name, the inputs you used, and the result you expected. That is enough to reproduce it.
• Want a calculator that is not here? Tell us what you are trying to buy or build. Requests shape what gets added next.
• Advertising or business questions go to the same address.

We read everything and usually reply within a few days. We cannot give project-specific engineering or code advice by email.
