### 5/5 — 5 stars

*2026-06-13*

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!

### 5/5 — A game-changer for sourdough bakers

*2026-04-23*

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!

**Developer response:** 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 !

## Version history (last 5 releases)

### 2.5.1 — 2026-08-02

We've updated our Terms of Use and Privacy Policy; accordingly, Crumb is now rated 16+. We've also fixed a few minor bugs.

### 2.5.0 — 2026-07-09

New: a Yearly subscription for Crumb+, next to Weekly, Monthly, and Lifetime.
Trial change: the 3-day free trial is now only on the Monthly and Yearly plans.
Our Terms of Use and Privacy Policy are updated.

### 2.4.0 — 2026-06-30

New: Total hydration that counts your starter. The Dough Formula now shows a Total Hydration figure that folds in the flour and water from your levain — right next to the usual dough hydration — with a short note under each so you always know which is which. In bakes and recipes.

New: Name your flours. Add the brand and exact flour to anything in your blend  — in starters, bakes, and recipes. Your custom name then shows up everywhere the blend appears, on cards and in exports.

New: Autolyse timing. Log an autolyse duration on your bakes.

New: Two-stage oven temperatures. Set a different temperature for the covered (lid on) and uncovered (lid off) stages — made for Dutch-oven baking.

Plus crisper onboarding artwork and an update to our Terms of Use and Privacy Policy.

### 2.3.0 — 2026-06-17

New: editable bake dates. The new-bake form now uses a native date picker instead of a free-text field, and the bake detail screen lets you change the date inline. This also fixes an off-by-one bug where a date saved at UTC midnight read back a day earlier for users west of UTC ("submitted two days ago"); dates are now normalized to local midnight. Older bakes can be corrected with the new edit affordance.

New: recipe links. Recipes can now store an optional source URL: a "Recipe Link" field in the recipe form (works for standalone recipes too) and a tappable "Open recipe link" on the recipe detail that opens it in the system browser.

New: in-app feedback. A  "Feature Idea? Bug?" button on the Settings screen opens a form in the browser, so users can send feature requests and bug reports directly.

New bakes open for editing. Saving a new bake now lands you on that bake's detail screen instead of bouncing back to the list.

Oven-temperature field is easier to edit. Rewrote the temperature input. Applied to the new-bake, edit-bake, and recipe forms.

### 2.2.2 — 2026-06-02

We've fixed display issues across different screen sizes: buttons and content now fit and scroll correctly on every device, big or small. Thanks for baking with us!
