Open Plan and tap New plan. Choose a recipe and the time you want the bread ready, meaning baked and cooled enough to slice. Crumbline lists every step with clock times. Tap Start to keep the plan and tick steps off as you go.

Bulk time depends mostly on dough temperature and how much levain the formula uses. Warmer dough and more levain ferment faster. Each step in the plan explains how its length was worked out, so you can adjust the temperature or levain and see the effect straight away.

Built-in recipes stay as they are, so you always have a reference. Open one and tap Duplicate to make your own copy, then edit it freely. You can also tap + in Formula to write a recipe from scratch.

Log feedings in Starter and, later, when the starter peaked. Crumbline compares your starter with its model and tunes the suggested feeding ratio to the peak time you want. The more feedings you log, the closer it gets.

Open Settings and choose your units for temperature and weight. All recipes and plans follow the new units.

Set the hours when you would rather not be up handling dough, for example overnight, in Settings. Plan steps that fall inside them are flagged, and the first suggested ready time avoids them.

Not at the moment. Keep the plan open or note the clock times for each step.

Everything is stored on your device and included in your device backup. Restore the backup to a new iPhone or iPad and your recipes, plans and journals come with it. Deleting the app deletes its data.
