The sourdough companion
Bake sourdough. The old way.
duoni guides you through every step — from building a traditional hop starter to scoring your finished loaf with AI. For beginners and serious bakers alike.
Free to start — starter creation & daily care, always free
Sourdough is unforgiving
Starters die without warning
You fed it. You waited. Then nothing — a grey, deflated jar with no life left.
Timing is everything
Peak activity, bulk ferment, proof time — each window is narrow and invisible to the naked eye.
Every bake feels like a guess
Even experienced bakers walk away from the oven unsure what went wrong and how to fix it.
Everything in one app

What bakers say
“I've tried keeping a sourdough starter for years. duoni's daily reminders and feeding logs are the only thing that's ever kept mine alive past two weeks.”

“The AI scoring is genuinely useful — it told me my crumb was undermixed, not underproofed. Completely changed how I approach bulk fermentation.”

“Never tried a hop starter before. The step-by-step guidance made it feel manageable. First loaf in 10 days, and it actually tasted like real bread.”
