CrumbKeeper: Sourdough

CrumbKeeper predicts your sourdough from YOUR jar, in YOUR kitchen. Every sourdough app has a feeding log and a timer. CrumbKeeper has a calibration ladder. It starts with a published temperature model, switches to your jar's own median once you've logged three peaks, and once you've logged four peaks at different room temperatures it fits YOUR STARTER'S OWN TEMPERATURE-RESPONSE CURVE, a fingerprint of your jar. From then on, every prediction follows your thermostat: a warm afternoon and a cold snap get different answers, computed from your own history. Every predicted time on the Forecast board says which rung it came from. Always a window, never a promise. THE FORECAST BOARD Open the app to one screen that answers the only questions that matter: when does my starter peak, when does bulk finish, when does bread actually come out of the oven. Drag the kitchen-temperature slider and every window re-solves. IT WATCHES YOUR BULK AND ARGUES WITH YOUR PLAN Type two aliquot-jar heights and CrumbKeeper projects your bulk's finish from your dough's own measured rate. If that projection disagrees with your bake-day plan by more than 15 minutes, Bake Day says so ("your dough disagrees with the plan") and one tap re-solves the rest of the day around the dough. The dough is always right. THE STARTER FINGERPRINT Swipe a feed "Peaked now" and CrumbKeeper pairs it with the kitchen temperature you logged. Four peaks across a few degrees and your jar gets its own fitted curve, drawn point by point on its detail screen. The curve comes from your own logged peaks, not from a generic table. BAKE DAY, BACKWARD THEN FORWARD "Bread out of the oven at 6 PM Saturday" plans the whole day backward (levain, autolyse, mix, bulk, preshape, bench rest, shape, retard, bake), then runs it forward with notifications, and re-plans in one tap when reality drifts. AND THE REST • 14-day from-scratch starter program that explains the scary days • Feeding reminders, peak alerts and a next-feed widget • Baker's math: dough vs true hydration, multi-flour blends, stiff levains • Fix My Loaf triage that reads your own numbers, not a FAQ • Journal with crumb photos and bake-over-bake deltas • CSV export, full backup, and a converter FREE, AND PRIVATE Everything is free: no subscription, no ads, no account.
