Contact ToolsZio

We would like to hear from you — especially if you found a wrong result, a broken page, or a tool that does not work the way it should. Corrections are our first priority: tell us the tool, the numbers you entered, and the answer you expected, and we will check it and fix it.

ToolsZio is a small, one-person site, so your message goes straight to the person who runs it — there is no support desk and no ticket queue. We aim to reply within a few working days. If your question is about how a calculation works, the worked example and the frequently asked questions on the tool's own page usually answer it faster than email, and the ToolsZio blog walks through common examples step by step.

Send Us a Message

Email us at contact@toolszio.com. Please include the name of the tool or page in your subject line so your message reaches the right place quickly. We aim to reply within a few working days.

You can also use the form below. Please note: this form is not a live server form. There is no backend on this site and the form does not submit anything to a server. When you press Send, it opens your own email app with a pre-filled message addressed to contact@toolszio.com — nothing is sent until you press Send in your email app, and your message goes only to the address above. If your email app does not open, just email contact@toolszio.com directly instead.
