Perfumer Studio: Formula Lab

Formulate perfume the way a working perfumer actually does: in parts, with real weights, on a balance, with every batch written down. Perfumer Studio is a complete formulation bench — a live formula table, a weighing mode built for gloves and a real scale, timed evaluations, and stock that knows the difference between a neat material and a 10% dilution. Everything stays on your device. No account, no cloud, no subscription to keep your own formulas readable. THE FORMULA TABLE • Type in parts, percent or grams — it recalculates as you type • Nest a base inside a formula and see it expand into real materials • A carrier line that fills the remainder for you • Cost per kilo of concentrate and of finished product, live • The pyramid — top, heart, base — from the materials themselves • Save any version, compare two side by side, lock the one you compounded WEIGH IT PROPERLY • A full-screen bench: one line at a time, big numerals, a twelve-key pad, no keyboard • Tolerance per line from your balance's actual readability • A gross-weight check at the end that catches what the per-line check cannot • Progress survives the app closing mid-batch KNOW WHAT IS IN IT • EU 26 allergen declaration computed for the finished product, at the leave-on or rinse-off threshold • Usage limits per category, with a fit tool that brings an over-limit material back down • It tells you what it does not know: a material with no data is never reported as clean STOCK THAT MATCHES REALITY • Bottles, not just materials — strength, lot, supplier, expiry • An append-only ledger, so the number on the shelf and the number on screen agree • Trace a lot in both directions, through dilutions • Shopping list from what your planned batches actually need SMELL IT AND RECORD IT • Timed checkpoints — 15 min, 1 h, 4 h, 24 h, or your own ladder • Your own rating axes, not ours • Every observation tied to the batch you actually compounded, with its real weights and lots YOURS, OFFLINE Your studio is one SQLite file you can copy, back up and open with any tool. The app makes a backup on launch. It never phones anywhere. FOR Independent perfumers, students, indie fragrance brands, soap and candle makers, and anyone tired of a spreadsheet that cannot tell grams from parts.
