Monu Tools is built and maintained by Maxwell Aboagye in Hamburg, Germany. I read every message. Whether you have found a bug, have an idea for a tool, spotted a wrong number in one of the calculators, or just want to say hello, please get in touch.
I usually reply within a few days. For bug reports, telling me which tool, which browser, and what you expected to happen helps me fix things faster.
