Utilario is built around what people actually need, so messages genuinely shape what gets built next.
Email is the only contact channel — there is no phone line and no contact form to fill in.
Suggest a tool
Tell us the task in your own words — "work out how much paint I need", "split a bill by person" — rather than a tool name. Describing the problem is more useful than describing a solution, and it is how most of the tools here started.
Report a wrong result
If a calculation looks wrong, please include the tool name, exactly what you entered, what you expected and what you got. Calculation reports are treated as the highest priority: a tool that gives a wrong answer is worse than no tool at all.
Advertising and partnerships
Utilario is free and supported by advertising. For enquiries about advertising or sponsorship, use the same address with "Advertising" in the subject line.
Privacy questions
