We read every message. Whether you found a math error, want a new calculator, or just want to say hello — we’d love to hear from you.

For corrections

If you believe a calculator is producing an incorrect result, please include: the tool name, the inputs you entered, the output you received, and (if possible) the official source you compared it against. We will investigate and fix verified errors quickly.

For feature requests

Tell us what calculation you need and when you need it. Our roadmap is shaped by real requests from real users.
