Found a result that looks wrong? Want a calculator we don't have yet? We read every message people send us — feedback is how CalcViso gets better.
Our contact channel is coming soon
We're setting up a dedicated inbox and message form for CalcViso. It will appear on this page shortly — please check back soon. Until then, everything below explains what to include when you write, so your message gets answered fast.
What we'd love to hear
- A result that looks wrong. Tell us the tool's name, the numbers you entered, and what you expected — that is everything we need to reproduce and fix it.
- A tool you'd like us to build. If a calculator or converter is missing, describe the job it should do. The most-requested tools get built first.
- Something broken or confusing. A button that doesn't work on your phone, a label that makes no sense, a page that loads slowly — we want to know.
- Accessibility problems. If any part of CalcViso is hard to read or use with assistive technology, tell us and we will fix it.
One safety note
CalcViso will never ask you for passwords, bank details or personal documents — and you should never send them. Our tools need no personal information at all, and neither do we.
