A free lye calculator and an oil reference on soapledger.com
A free lye calculator on the website, with no account needed. It uses the same calculation engine and oil data as the app: NaOH, KOH or dual lye, purity, superfat and three ways to set the water.
A reference page for every oil with a sourced SAP value: NaOH and KOH SAP, fatty acids, iodine and INS where we have them, and the sources behind each number.

Tweaker, Blend Advisor and fatty acids for 114 oils

The Blend Advisor suggests oil changes that move toward the qualities you want.
