Sourdough Tracker - Crumb

AI Bake Coach, 30+ recipes, Starter Insights & journal search. Version 1.1 — the most complete sourdough companion.

Crumb is your complete sourdough companion — the app that turns a demanding craft into a daily joy. Whether you're nurturing your first starter or perfecting your hundredth loaf, Crumb keeps you on track from flour to crust.

STARTER TRACKER Your sourdough starter is a living thing, and Crumb treats it that way. A beautiful health ring shows your starter's current vitality at a glance — fed, hungry, or peaked. Set custom feeding schedules and Crumb reminds you before your starter goes hungry. Track feeding history, hydration ratios, and streak days to build consistency and understand what makes your culture thrive. Never lose a starter to neglect again.

RECIPE LIBRARY Crumb ships with 30 expertly crafted recipes spanning beginner to advanced — from a classic country loaf to high-hydration baguettes and whole-grain miche. Every recipe is written by bakers, for bakers, with clear rationale behind each step. Pro subscribers unlock the full premium library: seasonal specials, heritage grain formulas, enriched loaves, and more — updated regularly.

STEP-BY-STEP BAKE SESSIONS Baking sourdough demands precision and timing. Crumb's guided bake sessions walk you through every stage: autolyse, bulk fermentation, stretch-and-fold intervals, shaping, proofing, and baking. Built-in timers fire at exactly the right moment. Your hands stay in the dough, not on your phone.

BAKE JOURNAL Every bake tells a story. Log your results with photos, star ratings, hydration level, and free-form notes. Over time your journal becomes your personal recipe development log — spot patterns, refine techniques, and watch your bakes improve bake by bake. Search past bakes by date, recipe, or rating.
