🧼 SoapLog · soap & candle batch records
A soap batch tracker that counts down your cure for you
If you make cold-process soap, melt & pour, or hand-poured candles, you're juggling more batches than you can keep in your head — what's curing, what's ready, which fragrance load worked, how many bars you actually got. SoapLog is a focused batch tracker app that lives on your phone and works fully offline. Log a batch in under a minute and it does the date math for you.
Open SoapLog — free →Track each batch end to end
Pick the type — cold-process, hot-process, melt & pour, or candle — and the form adapts. Soap batches capture oils, lye (NaOH/KOH), water and superfat; candles capture wax and fragrance load. Add colorant, yield, a 1–5 rating and notes on how it behaved. Everything is saved locally in your browser; nothing leaves your device and there's no account to create.
Never lose track of a curing batch
Give a soap batch its cure start date and cure length (four weeks by default for CP soap) and SoapLog shows a running ready-on countdown. The home screen surfaces every batch currently curing, flags the ones that are ready, and keeps a clean reverse-chronological history of everything you've ever made.
