BakeyJakey is a sourdough calculator, baker's percentage lab, fermentation scheduler and scoring studio in one pocket-sized app. No accounts, no network, no permissions.
Slide the ratios and watch every ingredient rescale in grams.
Starter is counted as 100% hydration. Its flour and water are included in the totals.
Four-factor method: find the water temperature that lands your dough on target.
Water temp = (DDT x 4) - room - flour - starter - friction.
Dial in flour blends, hydration from 60% to 85%+, starter inoculation and salt, with dynamic scaling for any batch size.
Work out Desired Dough Temperature from ambient, flour and water conditions, then follow your stretch-and-fold timers.
Sketch blade cuts on virtual boules and batards, with lame angle guidance for ears that open beautifully.
Record crumb density, blisters, crust color, oven spring and room conditions, all stored offline.
Zero device permissions, no network calls, no subscriptions and no paywalls. Just you and your starter.
🥖 We are a small crew of bread-obsessed makers who got tired of scribbling ratios on flour-dusted napkins. BakeyJakey grew out of real kitchens, real starters and a lot of dense, gummy loaves.
🌾 Our mission is simple: make great sourdough feel approachable. We want every home baker to understand hydration, fermentation and shaping with the confidence of a seasoned artisan.
🧑🍳 In your hands, the app becomes a calculator, a dough thermometer coach, a scoring sketchpad and a crumb diary. It works fully offline, asks for zero permissions and never charges a subscription.
Measure twice, score once, bake bold.

BakeyJakey does not collect, store or share any data. Everything you enter stays on your device.
None. We do not gather personal details, recipes, dough measurements, crumb logs, scoring sketches or device identifiers.
Since nothing is collected, nothing is used, analyzed, profiled or sold. Your bakes are yours alone.
Calculations, schedules and logs live only in the app's local storage on your device. There is no cloud and no remote server.
BakeyJakey includes no analytics, advertising networks or trackers, and makes no network calls at all.
Because the app works entirely offline with zero permissions, your information never travels anywhere and stays protected by your device's own security.
We collect nothing from anyone, including children under 13, so the app is consistent with COPPA expectations.
There are no accounts to manage. To erase all app data, simply uninstall BakeyJakey from your device.
If this policy ever changes, we will update the effective date above and publish the revised text in the app listing.
