CrumbLog is a baking log for sourdough. Log every loaf with its formula, folds, and proof times, rate the crumb, and compare your bakes to see the hydration that made your best. No account, no tracking. Everything lives on your device and in your private iCloud, and syncs across your iPhone and iPad.

Baker's Percentages, Done Right

Enter flour, water, starter, and salt in grams and CrumbLog folds the levain's own flour and water into the totals, so hydration and salt read true. Every bake shows its hydration, salt, and levain percentages.

A Bake Log That Remembers

Autolyse, folds, bulk, final proof, bake time, and oven temperature on every loaf, with a crumb photo and a five star rating. The gallery becomes the visual record of your baking.

Best Bake Compare

CrumbLog plots hydration against the rating you gave each crumb, averages your rating by hydration band, and names the sweet spot. "What made my best crumb" gets an answer from your own loaves.

Recipe Scaling by Flour Weight

Scale any formula to a new total flour, a target dough weight, or a number of loaves. Every ingredient moves together, so hydration and salt hold exactly.

Bake Day Timeline

Enter your step lengths and pick when to start or when the bread should come out of the oven. CrumbLog lays out autolyse, folds, shape, proof, preheat, and bake with a time on each step.

Starter Feeding Tracker

Set your feed ratio and CrumbLog turns it into grams on the scale. Log every feeding with rise time and temperature, watch the age climb, and see when the next feeding is due.

On Every Screen You Own

CrumbLog syncs across iPhone and iPad with iCloud. The iPad layout sets the formula beside the process, with the compare charts side by side.

Free Vs Pro

Free includes 5 bakes with every tool: baker's percentages, recipe scaling, the bake day timeline, the crumb gallery, and the best bake compare. Pro unlocks unlimited bakes, starter feeding reminders, and exports: a printable recipe card PDF for any loaf and a CSV of every bake.

Pro is offered as a monthly subscription, a yearly subscription, or a one-time lifetime unlock. The current price is shown in the app and on this page before you buy.

CrumbLog is a baking log for your own records. Feed, bake, rate, compare.

Cancel anytime in Settings > Apple Account > Subscriptions; cancellation applies at the end of the current period.
