## What is Lye & Loaf?

Lye and Loaf is a cold-process soap calculator and cure tracker for serious makers.

Blend your oils, set the lye and superfat, and watch the numbers update as you type. See the quality of the bar before you pour, print a card to keep beside the pot, and follow every cure with an in-app countdown. Everything runs on your device.

- 30+ hand-checked oils with values for sodium and potassium hydroxide
- Add any oil you use - cranberry butter, mango, exotic blends - with full fatty-acid detail
- Unit toggle for ounces, grams, pounds and kilograms
- Set lye purity, superfat and water discount with sane limits and clear warnings
- Quality preview - hardness, cleansing, conditioning, bubbly, creamy, INS, iodine
- Printable card with a code linking back to the batch in the app
- In-app cure countdown, one per batch, anchored to a real cut date

A note on safety: lye is caustic and the bar is not safe to use until it has fully cured. This app does the arithmetic from the values you enter - it makes no skin-safety or chemistry-safety promise beyond the math. Always double-check your figures, wear protection, and follow trusted cold-process guidance.
