5 stars

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

Response from developer

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!

A game-changer for sourdough bakers

I got this for my mom, and it’s been incredible for her baking. Instead of keeping scattered notes, she now has one organized place to log feedings, track hydration, and document every loaf. It’s helped her really understand her process and consistently improve her results. Highly recommended for anyone serious about sourdough!

This is exactly what Crumb is built for. Having everything in one place makes a real difference when you’re trying to improve consistently, especially with something as nuanced as sourdough. Glad it’s been so useful for your mom, and appreciate the recommendation !
