Six things you'll use every bake.
Native iOS, offline-first, $9.99 once. Built in SwiftUI for iOS 26.4+. Optional iCloud sync via CloudKit — no servers, no analytics, no ads.
Peak prediction & alerts
A heads-up fires ~30 min before your starter peaks. The predictor adjusts for kitchen temperature.
Recipe OCR
Point the camera at a cookbook or screenshot. On-device Vision parses ingredients, grams, baker's %, and steps.
Bake log with recipe inlined
Photos, formula, rating, tags, notes — plus the full recipe you used, attached to every bake.
Offline recipe sharing
AirDrop or text a .sourdoughrecipe file. Photos travel inside it. No accounts, no cloud.
Calculator + 40 recipes
Feeding ratios, hydration, baker's percentages. Plus 40+ curated recipes from beginner loaves to croissants.
Private & offline by default
Zero analytics, zero SDKs, zero network calls. iCloud sync is opt-in via Apple's encrypted CloudKit.
No subscription. No ads. Yours forever.
Thirteen reasons the app is worth $9.99 once.
One price, forever
$9.99 once. No subscription, no account, no ads. Pays for itself in two months vs. any subscription competitor.
Works completely offline
No login, no Wi-Fi, no servers. Open on a plane, in a kitchen with no signal, on a brand-new iPad — it just works.
Smart starter tracking
Live time-since-fed, predicted peak, and rise multiplier on the home screen. Adjusted for your kitchen temperature.
Never miss a peak
Local notification ~30 min before your starter peaks. No push servers required.
Recipe OCR from a photo
On-device Vision parses titles, ingredients (with auto-baker's %), and steps. Then it's editable and yours.
Offline recipe & bake sharing
Custom .sourdoughrecipe and .sourdoughbake files. AirDrop or iMessage to a friend — photos included.
Forty-plus included recipes
Basic, Advanced, Breakfast, Snacks, Sweets — from a beginner sandwich loaf to laminated sourdough croissants.
Bake log with the recipe baked in
Photos, formula, rating, tags, notes. The full recipe you used is inlined into every bake's detail view.
In-app troubleshooting
Twenty problem-and-fix cards: pink streaks, hooch, acetone, gummy crumb, no oven spring, burnt bottom. No Googling at 6 AM.
Editable bake timer
Persistent across app restarts. Set "Bulk ferment 4h" on the home screen and a local notification fires when done.
Privacy by design
Zero third-party SDKs, zero analytics, zero tracking. iCloud sync is opt-in and uses Apple's encrypted CloudKit.
Custom bread iconography
Hand-drawn loaf and wheat-stalk shapes throughout. Light, dark, and tinted app icon variants for every home screen.
Reset and start over
One button in Settings wipes every byte and restarts the tutorial. Your purchase is preserved — wipes don't cost you money.
Track your starter, predict peaks, log bakes with photos, scan recipes from photos, trade .sourdoughrecipe files with friends — all offline, no account, no subscription, $9.99 once.
Coming Soon$9.99 · one-time · iOSHi, I'm Sarah. I've killed seven starters.
I started baking sourdough in 2019 and immediately found every way it can go wrong. After the seventh dead starter and the third Saturday spent baking at midnight because I missed peak, I started building the app I wished I had.
The site is everything I wish I'd known. The app is the assistant I wish I'd had — one purchase, no subscription, no tracking. Just bread.

The honest answers.
Is it really one-time, or does $9.99 unlock a subscription later?
Really one-time. You pay $9.99 once, you own the app forever, every feature works on day one. No tiers, no "premium" upsell, no recurring charge buried in settings. Restore Purchase is supported on new devices.
Does it really work offline?
Yes. There are no servers and no required login. Every feature — peak detection, notifications, the calculator, the 40+ included recipes, the bake log, the OCR — runs on-device. Open the app on a plane or in a kitchen with no signal and it just works.
What about Android?
Not yet. I'm one person and iOS was where I had the bandwidth to start, built natively in SwiftUI for iOS 26.4+. If enough Android folks ask, it's next.
Why is the website free if the app costs money?
The site is where you learn. The app is where you bake. Reading about sourdough doesn't need a paid app, but feeding reminders, peak detection, and a bake log do. Different jobs.
Will my data be sold or tracked?
No. Zero third-party SDKs, zero analytics, zero network calls. Nothing leaves your device unless you choose to enable iCloud sync — and that uses Apple's encrypted CloudKit, never our servers (we don't have any).
How does the recipe scanning work?
Point your camera at a cookbook page or screenshot. On-device Vision text recognition parses the title, ingredients (with grams + auto-calculated baker's percentages), and step-by-step instructions. No image ever leaves your phone. The result is editable and yours to keep.
Can I share recipes with friends who also have the app?
Yes — via .sourdoughrecipe and .sourdoughbake files. Tap Share, send over AirDrop, iMessage, or email, and the recipient taps to import. Photos travel inside the file. No accounts, no cloud middleman.
I already use [other sourdough app]. Should I switch?
Honestly? If you're happy, no. If your current app is full of ads, gates the calculator behind a subscription, or doesn't have peak prediction — give this one a look. It's $9.99 once and works offline.
Stop missing peak.
Start logging bakes.
The app does the watching so you can do the baking. One purchase, yours forever.
No subscription. No ads. Yours forever.
