rhand.app Free Tools
rhand.app is a collection of free online tools built and maintained by RH Studio — 67 tools across up to six languages, from Korean life calculators (severance pay, take-home pay, jeonse conversion) to developer utilities and international size converters. No signup required.
Every calculator is built against the relevant statutes, official rates, or international standards (RFCs, ISO), with sources and a last-reviewed date shown at the bottom of each tool. Your input is processed entirely in the browser and never sent to our servers. When laws or rates change, we update the tool and its review date.
