S.D Timer vs Sourdough Schedule

S.D TIMER computes the exact feeding schedule for your sourdough starter, working backward from your target ready time to give you a precise feed time and gram-level recipe. HOW IT WORKS Enter six parameters: target ready time, quantity of starter needed (grams), desired hydration percentage, flour type, starter activity level (%), and ambient temperature (°C or °F). The app applies a fermentation kinetics model that factors temperature-dependent metabolic rates of lactic acid bacteria and wild yeast to calculate when your starter will hit peak activity. OUTPUT — YOUR FEEDING PLAN • Feed time: the exact moment to feed so your starter peaks on schedule • Starter / flour / water quantities in grams • Feed ratio (e.g., 1:9.8:9.8) • Estimated peak pH • Predicted flavor profile (mild, balanced, tangy, complex) • Recommended bread types suited to the resulting starter profile • Fermentation timeline chart with 80% activity window marked Set process alarms directly from the results screen to get notified at feed time and at peak. DESIGNED FOR PRECISION Temperature has a nonlinear effect on fermentation speed. A 5°C difference between summer and winter kitchens can shift peak time by 2–4 hours. S.D TIMER accounts for this so your timing stays consistent regardless of ambient conditions. Supports both Celsius and Fahrenheit. Works across all flour types including whole wheat, rye, spelt, and einkorn. Starter activity input lets you calibrate for your specific culture's behavior.

Tell the app when you want to pull the bread from the oven, and it works backward to build your entire timeline: when to feed your starter, when to mix, when to fold, when to shape, when to retard in the fridge, and when to score and bake. Built for beginners learning their first country loaf and refined enough for experienced bakers running long cold ferments and high-hydration doughs. WHAT YOU CAN DO Reverse-Time Scheduler Pick your finish time. The app calculates every step before it — starter feed, levain, autolyse, bulk fermentation, stretch and folds, pre-shape, bench rest, final shape, cold retard, preheat, bake, cool. Every step lands on a real time on your calendar. Step-by-Step Reminders Local reminders for every stage so you never miss a fold or forget the dough in the fridge. Set lead times that match your routine. Starter Tracker Log every feeding with flour, water, ratio, temperature, and notes. Track your starter's rise activity over the last two weeks on a clean chart. Daily feeding reminders keep your culture alive and healthy.
