Soapie starts with the recipe builder because that is where trust starts. The screen is meant to keep the core variables legible: oils, lye, water method, superfat, and the resulting property ranges.
Why the builder matters
A soap app stops being useful if the calculator feels like a black box. The builder exists to make the math visible enough that a maker can review the formula before moving into production.
What the screen is trying to solve
- keep the oil list editable without losing the batch context
- show NaOH, KOH, or hybrid support in the same workflow
- surface property feedback early instead of after export
- make recipe saving and versioning feel like normal workshop work
Where to go next
If you want the reference-data side, read oil catalog and calculations. If you want the production side, continue to Make Mode and batch records.
