By iToolsLab Editorial TeamUpdated 14 October 2026How we build tools

We read every message. Tell us what you need.

What to write to us about

Bug reports: tell us the tool, what you entered, what you expected and what you saw. A screenshot helps.

Corrections: if a formula, fact or example is wrong, please say which page and what should change.

Tool requests: describe the task and who it helps. Popular requests move to the top of our list.

Business and advertising questions are welcome too.

We aim to reply within three working days. We cannot give personal legal, financial, medical or tax advice.
