About NailCalc

NailCalc is a collection of free online tools. Free project calculators — concrete, paint, tile, budgets. No signup, nothing leaves your browser.

Every tool on this site runs entirely in your browser. We don't ask you to sign up, and the numbers you type into a calculator are never sent to our servers — because there is no server processing involved.

We build tools we'd want to use ourselves: fast, honest, and free of dark patterns.
