Log your daily starter feedings, learn when your sourdough starter peaks, time every phase of your dough, and keep a record of every homemade loaf in one place. Whether you are nurturing your very first starter or baking weekly for family and friends, Crumb keeps a clear history of your bread making: feedings and discards, dough preparation steps, your go-to baking recipes, and timers from autolyse through the final bake. By tracking your own process you start to understand fermentation timing, hydration ratios, proofing windows, and how small adjustments shape the final crumb.
