our story

About Us

🥖 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.
