What's New in Soaper

1.8.0

October 8, 2026

Pour one batch into several molds, and let Soaper do the math. • Several molds per batch. See how far the batter reaches, and size the recipe to fill them. • Buying six bottles? Enter the count and one price. "Bought before" remembers your container sizes. • Price a recipe's missing items from one sheet, or add a price from any inventory row. • Every lye amount states its purity, and the editor warns when the essential-oil load climbs. • Custom ingredient names are never translated, and search uses the name you see. • iPad shows the recipe list and the recipe side by side. • Blend Lab starts from your own superfat, water and lye defaults. • One cure time per batch, everywhere it is quoted, plus a longer cure-timer preset. • Quick Batch has a Batch Size control: change the size for one batch, or save it to the recipe. • The Workshop Checklist prints the mold you chose. • Siri: "Create a recipe" fills in the form, and "Start a batch" opens it. • Apple Watch timers stay in step with your phone. • Choose which Recipe Insights sections you want; the choice syncs to your other devices. • Liquid soap recipes show when they suit a foaming pump. • Settings shows when your library last synced. Plus a round of stability fixes.

Thorough and easy to use

Great for beginners!

Fantastic App!!!

I just started making soap last month. I cannot even begin to know how to use soapcalc. This made the process of creating a soap recipe easy and fun. With the added inventory function, I’ll be able to track everything I use.
