Lyestone is a soap maker's lye calculator that lives on your phone, not behind a paywall and a slow website. Pick the fats in your recipe and enter their grams. Set your superfat and water. Lyestone computes - in real time, as you slide - the exact grams of sodium hydroxide (NaOH) for a bar soap, or potassium hydroxide (KOH) for a liquid soap. Same recipe, both lye types, one tap to switch. WHAT'S BUNDLED • 43 saponifiable fats, ready out of the box - olive, coconut (76 and 92 degree), palm, palm kernel, lard, tallow, castor, shea, cocoa butter, mango butter, kokum, hemp, sweet almond, avocado, jojoba (treated correctly as a wax), babassu, sunflower, rice bran, sesame, neem, soybean, peanut, walnut, hazelnut, apricot kernel, grapeseed, evening primrose, argan, abyssinian, tamanu, meadowfoam, andiroba, rosehip, borage, pumpkin seed, marula, baobab, camelina, perilla, poppy seed, pomegranate, and beeswax. • SAP values for both NaOH and KOH, cross-checked against canonical references (SoapCalc, ModernSoapmaking.com, the Handcrafted Soap & Cosmetic Guild table). • Per-recipe quality scores - hardness, cleansing, conditioning, bubbly, creamy - with a visible target band so you can tell at a glance whether your recipe is balanced. • Iodine value (DOS risk) and INS, the two most-cited stability numbers. • Quality warnings drawn from the literature: low conditioning, high cleansing, coconut-group dominance, wax-trace acceleration, KOH-superfat advisories, and more. Lyestone will tell you why your recipe is going to dry skin - before you pour it. PROFESSIONAL FEATURES • Lye concentration mode (master-batchers, soap-soaping by-the-spreadsheet types) - pin lye as a percentage of total solution instead of water-as-percentage-of-oils. 33% is one tap away. • Fragrance load in oz/lb of oils → grams. Salt addition. Milk-soap flag with a reminder to freeze the milk. • Markdown / CSV share - drop the calculation into your woodshop notebook, Reminders, or Messages with a single tap. • Per-fat detail cards: SAP values, contribution scores, iodine, INS, plus a one-line note on how the fat behaves in a bar. DESIGN PROMISE No accounts. No analytics. No internet. No ads. Lyestone is a one-time $0.99 purchase - no subscriptions, no tiers, no unlocks. The app works the same on your phone, your iPad on the workbench, and the iPad locked in the woodshop. SAFETY Sodium and potassium hydroxide are highly caustic. Always wear gloves and goggles. Add lye to water (not water to lye). Lyestone is a hobbyist reference - consult primary sources and a soap-making mentor before scaling production.

Lyestone 1.1 — three new features for makers who pour batches, not just calculate them. MOLD CALCULATOR Pick your mold shape (rectangular loaf, round cylinder, slab, individual cavities, or custom volume), enter its dimensions, and Lyestone tells you exactly how many grams of oils you need to fill it. Then choose any saved recipe and it scales every fat proportionally — one tap loads the scaled recipe straight into the editor. BATCH JOURNAL Log each batch you pour: which recipe, the actual oil weight, and the pour date. Lyestone shows a live cure progress bar, the minimum ready date (NaOH bar soap: 28 days; KOH liquid soap: 14 days), and the recommended ready date (42 days / 21 days). Cure timelines are based on published soap-making references. Delete a log at any time — everything stays on your device. STARTER RECIPE LIBRARY Ten well-known community recipes are now bundled — Classic Castile, Marseille 72, Bastille Bar, Heritage Tallow & Lard, Luxury Face Bar, Coconut Shampoo Bar, Sea Salt Bar, Liquid Soap Paste, Goat Milk Bar, and Cocoa Butter Luxury Bar. Tap any starter to preview its calculated numbers, then load it into the editor as your starting point. ALSO IN 1.1 • "Load into editor" button now works on saved recipe detail cards (was visually implied but missing — fixed). • New Batches tab in the bottom navigation. • Starter Recipes and Mold Calculator are one tap from the recipe editor menu (⋯).
