New to sourdough or juggling four starters — CrumbKeep keeps every feeding on schedule and turns a quick photo into a pro-level read on your starter and your crumb.
Keep your sourdough starter alive and bake better bread every time. CrumbKeep tells you exactly what to do and when — feeding reminders, rise timers, a bake journal, and an AI that reads your starter and your crumb like a pro baker.
Made for home bakers who want great bread without living in Reddit threads. No account, no ads. Everything you log stays on your phone.

WHY BAKERS SWITCH TO CRUMBKEEP
Most sourdough apps lock the basics behind a paywall and give you one vague scan. CrumbKeep keeps the tracker, reminders, calculator and journal free, and its AI gives advice tied to what's actually in your photo — not the same generic tip every time.
Cancel anytime. The free tools stay free.
CrumbKeep offers general baking guidance for home bakers.
