What Levain does
Levain is the thoughtful sourdough companion for home bakers who take their starter seriously. Log every feeding with flour-to-water ratios, trigger a rise timer the moment the jar is closed, and let Levain tell you when peak activity has arrived — so your bread goes in the oven at exactly the right moment. When bake day comes, the built-in hydration calculator turns any recipe into precise gram weights for flour, water, salt, and starter. Build a step-by-step schedule — autolyse, fold, shape, proof, bake — and get a gentle reminder at each stage. After the bake, photograph the crumb, rate the loaf, and save tasting notes alongside the exact formula you used, so you can repeat every success and learn from every flat loaf. Everything is stored on-device using SwiftData. No account required, no internet, no subscription. • Starter feeding log with ratio tracking and rise timer • Hydration calculator for flour, water, salt, and starter • Bake scheduler with step-by-step stage reminders • Crumb photo gallery with ratings and tasting notes • Full history — scroll back through every loaf you have ever baked
Features
Built to be useful, not noisy.
Starter feeding log
Record each feeding with date, flour grams, water grams, and ratio. The home screen surfaces last-fed time and a color-coded freshness indicator so you never lose track of a neglected starter.
Rise timer
One-tap timer that starts at feeding and lets you mark peak activity with a single tap. Rise history per feeding builds a baseline so you learn how your starter behaves across seasons and temperatures.
Bake editor with hydration calculator
Enter flour weight and target hydration percentage; Levain instantly computes water, salt (at a configurable percentage), and starter grams. Add a step-by-step schedule — autolyse, stretch-and-fold, shape, proof, bake — with optional stage reminders.
Bake detail and crumb gallery
Each completed bake stores a crumb photo, a 1–5 star rating, free-text tasting notes, and the exact hydration formula used. A scrollable history view lets bakers compare loaves side by side and trace improvement over time.
Why it exists
The problem
Sourdough bakers scatter feeding notes across notebooks, bake formulas across phone photos, and rise times across generic timer apps, making it nearly impossible to connect what the starter did to how the loaf turned out — or to replicate a great bake.
What's different
How Levain stands out
Levain uniquely unifies starter health tracking (feedings, ratios, rise timer, peak logging) with bake records (hydration calculator, schedule, crumb photos, ratings) in a single fully offline app — unlike The Bread Code spreadsheets, generic bread timers, or note-based workarounds, it creates a searchable personal ba…
