## Description

Get the lye right every time. Add your oils and instantly see NaOH, water, and how your bar will feel — hardness, cleansing, lather. Offline. No subscription.

Make soap with confidence. Soap Recipe & Lye Calculator does the one calculation
every batch depends on — the exact lye — and shows you how the finished bar will turn
out, before you pour.

Add your oils and butters, and instantly see:
• Precise lye (NaOH) and water for your batch, with your superfat and water settings
• A live quality readout — hardness, cleansing, conditioning, bubbly & creamy lather,
  plus iodine and INS — so you can balance a recipe before you make it
• Everything in grams, ounces, or percentages, with a library of 50 oils and butters

Go further with a one-time Pro unlock:
• Liquid soap (KOH) mode with lye purity
• Fragrance & essential-oil calculator
• Save and name unlimited recipes, with notes
• Resize any batch to your mold
• Export a clean, printable recipe sheet (PDF) to save or share

Why makers like it:
• Fast, beautiful, and works 100% offline — your recipes stay on your device
• Trustworthy oil data, aligned to established soapmaking references (see Data & Sources)
• One-time purchase. No subscription, no account, no clutter.

SAFETY: Lye is caustic. Always wear gloves and eye protection, add lye to water (never
water to lye), and make a small test batch — SAP values vary by oil source. This app is a
formulation aid; safe handling is your responsibility.
