A Few Common Questions
Can I request a new calculator? Absolutely — that's one of the most useful things you can send in. Just describe what you need it to do.
I found a calculation that looks wrong. What should I include? The calculator name, the numbers you entered, and what result you expected versus what you got. That's usually enough to track down the issue quickly.
Do you offer support for businesses or bulk use? AllCalc is a free, independent project — reach out through this form and we'll figure out what's possible.
