Store description excerpt
Yeast is the sourdough engine for people who care how fermentation actually behaves — not another recipe list, and definitely not an AI chatbot. Tell it your starter's feed ratio and your kitchen temperature: it predicts the peak — and the more you bake, the better it knows YOUR culture. Tell it when you want to bake: it back-solves the whole schedule — feeds, ferments, folds — so the last stage finishes exactly when you pull the loaf. The math is research-grounded and runs entirely on your phone. No account. No ads. No data leaves your device. FREE, AND GENEROUS • A sourdough starter with feed logging, peak predictions and reminders — plus an activation planner that back-solves your feed schedule from "ready to bake Saturday 9am". • The FULL pizza dough calculator — Direct, Biga, Poolish and Sourdough methods, multi-flour, backward-solved to your bake time. Free forever, no ads. • The Balance instrument — see whether your dough will land tenacious or extensible before you mix, with plain-language fixes when it drifts. • A bake journal with photos, plus saved presets. YEAST PRO • Per-starter calibration — log a real peak and predictions tune to YOUR culture. The more you bake, the sharper it gets. • Bread module — levain loaf recipes, the mix-water temperature to hit your target dough temp, and bulk-rise targets with aliquot-jar guidance. • Croissant module — lamination geometry for any fold sequence, butter-block quantities, and a proof-temperature guardrail. • Unlimited starters, unlimited journal entries, unlimited saved recipes, and every maker preset. WHY IT'S DIFFERENT Most apps count one number: total hours. Yeast models fermentation the way it actually works — time AND temperature, with separate curves for yeast activity and gluten breakdown. It knows a warm stage after a cold one behaves differently than the reverse. It knows every flour has a fermentation budget and warns you before you blow past it and the dough collapses. That's the difference between a timer and an engine that tells you why. PRIVATE BY DESIGN Everything runs on-device. No login, no tracking, no cloud. Your starters, your journal, your recipes — yours, on your phone. Fully available in English and German — interface and baking guidance.
