## What is Lyewise?

Lyewise is a soap calculator built for makers who sell what they make. Calculate lye and water with confidence, let the Optimizer design a recipe from the oils on your shelf, print ingredient labels with INCI names, and track every batch from mixing bowl to market table.

LYE CALCULATOR (FREE)
• 140+ oils, butters and waxes with reference SAP values and fatty acid profiles
• NaOH for bars, KOH for liquid soap, or dual lye
• Superfat, lye purity and three water methods: % of oils, lye concentration or water:lye ratio
• Fragrance by % or ounces per pound, citric acid compensation and additives
• Enter oils by percent or by weight, in grams, ounces or pounds
• Hardness, cleansing, conditioning, bubbly, creamy, iodine and INS with recommended ranges
• Fatty acid chart and plain-language warnings
• Size a recipe to your mold
• Starter recipes: castile, bastille, palm-free, salt bar and more

RECIPE OPTIMIZER (PRO)
Pick the oils you have, set limits like "coconut at most 30%", and choose a goal: balanced, gentle, big lather or hard and long-lasting. Lyewise finds the percentages that hit the target and can pick the cheapest blend using your supply prices.

INGREDIENT LABELS (PRO)
Generate ingredient lists in descending order by weight: INCI before saponification, saponified INCI (sodium olivate, sodium cocoate…) or plain English. Add your shop name, net weight and lot number, then export a printable PDF.

BATCHES & CURE TRACKING
• Make a batch from any recipe with an automatic lot number
• Step-by-step make mode with exact weights
• Cure countdown and a reminder when bars are ready
• Photos, notes and ratings for every batch

SUPPLIES & COST PER BAR (PRO)
Track stock and prices for oils, lye, fragrance and packaging. Each batch shows its cost per bar, and making a batch takes ingredients out of stock.

PRIVATE BY DESIGN
No account, no ads, no tracking. Your recipes stay on your iPhone.

SAFETY
Lye is caustic. Lyewise calculates from reference data; always double-check a recipe before you make it. Labeling rules differ by country.

Lyewise Pro is available as a monthly or yearly subscription (the yearly plan includes a free trial) or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period.
