A Sourdough Bake Log App for Repeatable Loaves

The difference between a lucky loaf and a reliable one is a record. SourdoughLog is a free bake log app that captures what you actually did each bake, so when a loaf comes out with a beautiful open crumb and a crackling ear, you can do it again on purpose.

What you record per bake

• Recipe / flour blend — e.g. "Country sourdough, 20% whole wheat".
• Hydration % — the biggest lever on crumb and handling. Higher hydration means a more open, custardy crumb but slacker dough.
• Bulk-ferment time — the make-or-break stage. Under-proofed dough bakes dense; over-proofed dough spreads and tears.
• Proof time & method — overnight cold retard, a couple of hours at room temperature, and everything in between.
• Oven setup — temperature and vessel, like "245°C Dutch oven" or "250°C steam + stone".
• Result rating (1–5) and crumb notes — ear, scoring, gummy base, sourness. Your future self will thank you.

Built-in hydration calculator

Hydration is just water divided by flour, but doing the math mid-bake with floury hands is no fun. SourdoughLog's hydration helper works both directions: enter flour and water grams to get the percentage, or set a target hydration and a flour weight to get the exact water to add. It is free and always available right above the bake form.

Spot your patterns

With a few bakes logged, the history makes trends obvious. Maybe your best-rated loaves all sit around 72% hydration with a five-hour bulk, or maybe a cold overnight proof consistently gives you the best ear. The log turns vague baking intuition into something you can read back and repeat. Everything is stored locally on your device — no account, no upload, fully offline.
