Candy Suds runs a four-step calculation process engineered for precision. First, select from 34 oils and butters with live percentage sliders that auto-balance to exactly 100g blend total. Second, adjust superfat percentage and water ratio to match your formula style. Third, review predicted soap characteristics including hardness score, cleansing power, conditioning rating, bubble quality, and projected shelf life. Fourth, name your formula, set cure days, and generate complete batch specifications.
Every metric calculates instantly as you adjust ingredients. The app displays total lye weight in grams for sodium hydroxide or potassium hydroxide, precise water volume, finished batch weight, per-bar weight, and per-bar cost when pantry pricing is enabled. Formulas save locally with no cloud sync, no account creation, and zero data transmission.
Batch tracking starts when you hit the clock button after pouring your mold. A circular progress timer counts cure days with ready-date projection. Batches move from Curing to Ready status automatically. Archive completed batches to maintain production history. The pantry module deducts ingredient quantities from stock as you create batches, triggering low-stock warnings before critical oils run out.
Choose from olive, coconut 76°, beef tallow, cocoa butter, shea, palm, castor, and 27 additional oils. Drag percentage sliders to build custom blends. Live balance indicator confirms when your formula reaches exactly 100g total.
Start batch tracking the moment you pour your mold. Circular progress indicators show remaining cure days with projected ready dates. Batches auto-transition from Curing to Ready status when cure time completes.
Enter ingredient prices once in Pantry module. Candy Suds calculates total batch cost, per-bar cost, and tracks ingredient depletion as you create batches. Low-stock warnings prevent mid-production shortages.
Before mixing a single drop, preview hardness rating, cleansing power, conditioning level, lather quality, and shelf life projections. Adjust oil percentages until prediction scores match your target soap characteristics.
