Lyestone 2.0 — a pro upgrade from a lye number to a full recipe formulator, still 100% offline. • Fatty-Acid Lab: real 8-acid profiles for all 43 fats, so your soap's Hardness, Cleansing, Conditioning, Bubbly, Creamy, Iodine, and INS are computed from actual chemistry — with a "who brings what" breakdown and a saturated/unsaturated split. • Additive calculator: citric acid with exact extra-lye compensation, plus sodium lactate, salt, clays, titanium dioxide, mica, and more in grams and teaspoons. • "Same water three ways": water-as-%-of-oils, lye concentration, and water:lye ratio that interconvert. • PDF recipe sheet export and an INCI ingredient-label generator (Sodium Olivate, and so on). All chemistry is computed on-device and oracle-verified. No account, no network — everything stays on your device.

Lyestone 1.2 - two features that were missing from every other lye calculator. BATCH COST BREAKDOWN Enter what you paid for each fat - per ounce, per pound, per kilogram, or per gram - and Lyestone calculates total batch cost, cost per bar, and a line-by-line ingredient breakdown in real time. Price your lye too, if you want the full picture. Prices are saved per ingredient and carry over to every recipe automatically. Share the full breakdown as plain text from the sheet. SCENT ADVISOR A 33-entry essential oil reference built for cold-process soap. For each scent, Lyestone shows the maximum recommended grams for your current oil weight, trace-speed rating (slow / moderate / accelerates / seizes fast), scent retention in cured soap (poor / moderate / good / excellent), safety notes where applicable, and actionable blending tips. Source: The Nerdy Farm Wife printable chart, cross-checked with Brambleberry and Lovin Soap Studio usage guides. Browse by category (Floral, Citrus, Herbal, Woodsy, Spice, Earthy, Fresh, Resinous) or search by name or scent profile. ALSO IN 1.2 - Both new tools open from the recipe editor menu () so the oil weight from your current recipe is always in scope. - Batch cost sheet includes a bar-weight slider with one-tap presets (2.5 oz / 3 oz / 3.5 oz / 4 oz / 5 oz). - Lye pricing toggle in the cost sheet is off by default - opt in only if you track NaOH / KOH cost.

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 (⋯).
