## What is Boule?

Boule is a calm log for your sourdough starters that runs entirely on your device.

Add a starter, set how often you feed it, and Boule counts down to the next feeding and reminds you when it is due. No account to create. Nothing leaves your device.

- Track several starters, each with its own cadence and flour blend
- Follow the in-app countdown to the next feeding and get a reminder when it is due
- Scan the jar to read how much it has risen since the last feeding, on device
- Work out flour, water, levain and salt in grams with baker percentages
- Keep simple bake notes for each loaf you pull from the oven
- A missed feeding softens into a rest state, never a guilt prompt

Boule is built for the home baker tending one to three jars on the counter. Every feature works in airplane mode, so a flour-covered kitchen with no signal is no problem.
