What is inside
Everything between a jar of starter and a good loaf.
Zymo covers the whole bake, from the first feed to the notes you write after the first slice.
Set a feeding rhythm and Zymo reminds you when Bubbles is hungry. Tap Fed now when you do it. Tapped too soon? Undo it.
Light and dark
Easy on the eyes, noon or 2 a.m.
Zymo is built like a kitchen counter, not a dashboard. Warm cream in the day, a deep oven brown at night, and one orange for the thing you are about to do. Checking on a starter in the dark should not feel like staring at a lamp.
- Rounded, readable type that scales with your phone settings
- Large tap targets for floury hands
- Gentle haptics you can switch off

The crew
Baking is easier with company.
Zymo comes with four small characters. They keep the app friendly when the dough is not.
Crumb
A loaf with answers. Your guide for every baking question.
Bubbles
Your starter in a jar. Hungry, ripe or sleepy, it tells you.
Sprout
Shows up when a bake goes well and cheers you on.
Baguette
Long, crusty and always happy to see you.
Privacy
Your bakes stay on your phone.
A sourdough journal is personal. Zymo keeps it on your device and says plainly what leaves it.
No account
Zymo has no sign-up and never asks for your email address. There is nothing to log in to.
Saved on your phone
Your journal, photos, plans and conversations live in the app's private storage. We keep no copy.
AI sees only what you send
A photo or message goes to our server and OpenAI when you scan or ask Crumb. Scan photos are deleted after analysis.
