FAQ

What exactly is Levain?
The all-in-one sourdough companion: a full course, a living starter tracker, a recipe library with guided bake mode, and a toolkit of calculators and timers, all bundled into one warm, offline app.
I'm a total beginner. Is this for me?
Absolutely. The course starts from your very first feed and explains the why, not just the steps. Pair it with the beginner recipes and Levain walks you all the way to your first loaf.
How does the peak estimate work?
Levain factors in your feed ratio, ambient temperature and whether the starter is on the counter or in the fridge, then shows a live rise curve with the moment it peaks, the sweet spot to bake.
Does it really work offline?
100%. No account, no cloud, no tracking. Every lesson, recipe and tool is bundled with the app and lives on your device. It works on a plane with zero signal.
What's the difference between Free and Premium?
Free gives you the starter tracker, the first course module, a handful of core recipes and the hydration calculator. Premium unlocks the full 27-lesson course, the entire recipe library with bake mode, the peak calculator, journal and every tool, with a 7-day free trial ($14.99/month or $99.99/year).
Which devices are supported?
iPhone on iOS 16 and later, in English, Português and Español. Levain follows your system light or dark theme automatically.
