A jar that tells you
Your starter rises in the app as it rises on the counter, with a predicted peak window — "ready about 3:30–5:00 pm", never a fake-precise minute.
Fed it — one tap
Log a feed with your usual amounts from the app, the widget or straight from the reminder. Quiet hours keep the night quiet.
Bread ready by Saturday 9:00
The ready-by planner works backwards through the bake and the starter: when to feed, build the levain, mix and shape.
Guided bakes
One step at a time with big timers, fold ticks, "what to look for" and a Live Activity on your Lock Screen.
Maths that counts your starter
Dough, feed, levain and water-temperature calculators — true hydration includes the flour and water inside your starter.
Starter Doctor
Hooch, odd smells, no rise? Answer a few questions and get a plan with times — not a guess. Mould always means start again.
