The short version
SolveNook is a free collection of 108 calculators, generators and browser utilities, grouped into construction, business, finance, energy, utilities, maths and developer tools. Examples include a square footage calculator that subtracts exclusions, a concrete calculator for slabs, footings and stairs, a mortgage calculator, an invoice generator and a HEIC to JPG converter. Tool pages explain their formulas and limits, and many offer a breakdown you can download. No account is needed. The site is operated by Renvoro Pty Ltd, and its privacy policy says calculator values, invoice fields and image conversions stay in your browser tab.
