## What is Crumb?

Tired of sourdough timing that's always off? Most apps give you fixed steps — but dough rises faster when it's warm and slower when it's cold. Crumb recalculates every step for YOUR dough temperature, so fresh bread is ready exactly when you want it.

TEMPERATURE-SMART SCHEDULE
Tell us when you want the loaf out of the oven. We work backwards through feed -> autolyse -> bulk -> fold -> shape -> proof -> bake, and recalculate every step for your dough temperature. Get a notification for each stage so you never miss a fold.

STARTER TRACKER
Log feedings, watch the rise curve, and get "time to peak" estimates plus feeding reminders. Keep multiple starters healthy and never wonder if yours is ready.

CALCULATORS (FREE)
- Baker's percentage calculator for any sourdough recipe
- Full pizza dough calculator — Neapolitan, New York and Pan styles
- Hydration calculator and handy unit converters
The calculators are free, forever.

CRUMB ANALYSIS
Snap a photo of your loaf and get feedback on crumb, crust and proofing, so your next bake is better than your last.

RECIPES & JOURNAL
Start from proven recipes, then save every bake with photos and notes to build your own baking log.
