Home bakers planning sourdough around their kitchen and schedule
Worth noticing
The site notes that a web app cannot wake a locked phone and recommends setting an ordinary alarm for overnight waits.

Field notes

The recipe list spans a 70% hydration first loaf, an 82% open-crumb dough for practiced hands, and focaccia that needs no shaping or Dutch oven. The calculator accounts for the flour and water in a levain, while the starter guide flags days 3 and 4 as a stage when jars may look inactive. Overnight step alerts have a stated limit: the app must remain open with the screen on.
