Sourdough Bread Proofing Timer

Read full description

Pick the moment you want to slice the loaf. Proofing Timer works backward through every fermentation step and tells you exactly when to mix, fold, shape, chill and bake. Most bread apps hand you a recipe and a stopwatch. Proofing Timer starts from the only time that matters, when you want to eat, and builds the whole schedule around it: autolyse, levain, bulk ferment, stretch and folds, preshape, final shape, cold proof, bake. Turn on reminders and your phone taps you on the shoulder at each stage, even with the app closed. WHAT YOU GET • A full bake schedule from one question: when should the loaf be ready? • Reminders for every fermentation stage, so no bulk ferment runs away from you again • Hydration in seconds: enter flour and water, or a target percentage, and get the answer • Bakers percentages for salt, levain and hydration on every recipe you save • A milestone log for each bake, from mix to oven, with notes on what you saw and felt • A history you can search, with a crumb score for every loaf so you can see what worked PERFECT FOR • Weekend bakers who want a Saturday loaf without a 5 a.m. alarm • Anyone whose starter is finally alive and wants the next bake to be repeatable • Bakers scaling a country loaf, ciabatta, focaccia, rye or brioche up or down • People who have lost track of a bulk ferment one too many times WHY NOT JUST USE NOTES AND A KITCHEN TIMER? A timer counts one stage. A recipe lists ingredients. Neither knows that a 12 hour cold proof and a 4 hour bulk mean you must mix by 3 p.m. on Friday to eat at noon on Saturday. Proofing Timer does that arithmetic for you, then remembers how every loaf turned out so the next one is better. PRIVATE BY DEFAULT Your recipes, schedules and bake history stay on this device. No account, no sign in, no ads, no tracking. Reminders are local notifications that never leave your phone. FULL ACCESS Proofing Timer is a paid app with three ways to unlock everything: a weekly subscription, a yearly subscription, or a one time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel them in your App Store account settings at any time. Payment is charged to your Apple ID at confirmation of purchase. Set your slicing time tonight and let Proofing Timer tell you when to start.
