Soap Lye Calculator – SoapCalc

I got tired of soap calculators that made simple things feel complicated — and of losing recipes I discovered in books, online, and while watching other soapmakers, because getting them into a calculator was such a hassle. I wanted a fast, reliable way to get safe lye amounts and bring those recipes home without friction. So I built Simple SoapCalc.
