Nothing uploads
Most tool sites send your files and figures to a server — then meter them. Kwikfig computes everything locally, in this tab. There is no server copy because there is no upload.
The working is shown
Every calculator prints its formula and worked examples, and every formula is checked against hand-verified test cases on every build. You can audit any number we give you.
Free means free
No accounts, no credits, no countdown timers, no watermarks. The site is funded by advertising, never by holding your own results hostage.
