## What is Soap Studio?

Your soap workshop, together on your device.

Soap Studio helps you calculate a formula, follow a making day and keep the exact version you made. Work offline with no workshop account or application server.

START WITH A RECIPE
• Calculate NaOH for cold-process and hot-process soap, or plan melt-and-pour recipes.
• Set superfat, NaOH purity and your water method: lye concentration, water-to-lye ratio or percentage of oils.
• Use the reference oil library with source information, or add a custom oil from your supplier’s data.
• Scale recipes, estimate mold capacity and record fragrance, color and other additions.
• Keep unlimited recipes, favorites, notes and saved versions.

FOLLOW YOUR MAKING DAY
• Plan batches that keep a snapshot of the recipe and ingredient data.
• Check off weighed ingredients, record actual quantities and continue where you left off.
• Follow unmolding and curing checks with optional local reminders.
• Add photos and notes, then record the batch’s actual yield.

KEEP CONTROL OF YOUR RECORDS
• Save portable backups with photos and restore a validated workshop file.
• Review CSV or Soap Studio JSON imports before adding records.
• Export data and printable recipe, bench and rack sheets.
• Choose your language, mass unit, currency and light or dark appearance.

OPTIONAL LIFETIME PRO
One non-consumable purchase unlocks connected material inventory, purchase and supplier lots, batch reservations and consumption, historical purchase costing, aggregate shopping needs, saved retail and wholesale prices, finished-stock movements and branded reports. Try the example workshop to explore these tools. No recurring subscription.

Recipes, calculation, make mode, batch history, manual cost estimates and full backups are included free, without recipe or batch limits.

Buying or restoring Pro requires internet access and the platform store. A verified purchase is cached by the purchase SDK. Restore with the same store account; Apple and Google purchases are separate. Workshop records do not automatically sync between devices.

Check formula inputs and supplier data before making. Reference SAP values and calculated properties are estimates, and curing reminders do not certify a finished soap. This version supports NaOH calculation; KOH and liquid-soap formulation are not included.
