CRUMB - Track your starter, time your bake, and perfect every loaf.
Crumb is a sourdough starter tracker and baking companion for home bakers who love the ritual of making real, artisan bread.
Log your daily starter feedings, learn when your sourdough starter peaks, time every phase of your dough, and keep a record of every homemade loaf in one place. Whether you are nurturing your very first starter or baking weekly for family and friends, Crumb keeps a clear history of your bread making: feedings and discards, dough preparation steps, your go-to baking recipes, and timers from autolyse through the final bake.
By tracking your own process you start to understand fermentation timing, hydration ratios, proofing windows, and how small adjustments shape the final crumb.

Just started my sourdough journey and downloaded this app to keep track of all my bakes. Really enjoying it so far - lets you add 5 or 6 photos of each (so I don’t have to keep hundreds of photos of bread in my camera roll), track everything I need to track including my starter feedings, and has some tools built in that I haven’t used yet but expect could come in handy down the road. Would love to see a “community” section at some point where you can view and save other peoples recipes, follow one another, ask questions etc. All in all definitely happy with this app
Developer Response
Thank you so much for the 5-star review and for taking the time to share your experience! I'm really happy to hear that Crumb is helping you document your sourdough journey and keep all your bake photos and notes organized.A community feature is actually something I have planned for the near future. Before that, I'm currently working on a dedicated Features & Bugs section inside the app, making it easier for users to suggest ideas, report issues, and help shape future updates.I've released multiple updates since launch and have many more planned. Thank you again for your support, your feedback, and for being part of the Crumb journey!
