Lyeria is an Android soap calculator that works out the lye and water for your soap recipe. Pick your oils, enter grams, ounces or percentages, and you get the NaOH, KOH and water to weigh, shown at the top of the screen while you type. A weighing checklist lists water, lye, then each oil, so you can tap each one off. Get the oil amount from the inside size of your mold, and compare soap qualities like hardness and lather with a saved recipe. If you sell your soap, the one-time Lyeria Pro purchase adds cost and a suggested price per bar, plus ingredient labels with INCI names. Made and published by GRAMSHIFT.
