🧼 SoapLog · soap & candle batch records
A soap making recipe log that remembers every batch
Soapers keep their best recipes on scraps of paper, in a notebook splashed with lye, or in a spreadsheet that never gets opened at the bench. SoapLog turns that into a clean, searchable log you carry in your pocket. For every batch you record the oils and fats with amounts, the lye you used (NaOH for bar soap or KOH for liquid), your water/liquid and superfat percentage, plus fragrance or essential oil, colorant and final yield. Next time you want to repeat — or tweak — a recipe, the exact numbers are right there.

Cold-process and hot-process soap depend on getting the lye-to-oils ratio right. Writing down the actual lye weight, water amount and the superfat % you ran lets you reproduce a batch that came out perfectly — and diagnose one that didn't (too soft, lye-heavy, dragging trace). A consistent recipe log is also the backbone of honest batch records if you ever sell your soap.
Cure times handled for you
Cold-process soap needs to cure, usually around four weeks, before it's ready to use or sell. SoapLog records your cure start date and cure length, then shows a live "ready on" countdown so you stop guessing whether last month's batch is done. The home screen lists everything currently curing, newest-ready first.
