LoafLab: Sourdough Planner

A home baker's companion for sourdough. LoafLab helps you plan recipes, time your starter, schedule your bake around your day, and remember every loaf. No sign-up. Offline.

Recipes Build formulas in grams and baker's percentages. Set flour and hydration, and LoafLab calculates water, salt, and starter. Scale to any number of loaves. Save as many recipes as you want.

Starter planner Tell LoafLab your feeding ratio (1:1:1, 1:5:5, or whatever your starter likes), your kitchen temperature, and when you want to mix. It estimates when to feed so your starter peaks on time, with an optional reminder. Calibrated against real baker guidance.

Plan your bake Pick a mix time or a finish time. LoafLab generates a schedule with autolyse, stretch and folds, bulk fermentation, shape, proof (room temp or cold retard), and covered plus uncovered bake. Customize any step and save your defaults.

Active bake Tap Start and a checklist walks you through each step with timers and reminders. Adjust a step's time mid-bake if things run long. Check steps off as you go.

Journal Log every bake with photos, a 1 to 5 star rating, dough and ambient temperatures, oven settings, steam method, notes on what worked, and tags. Search and filter your history. Turn a past bake back into a new recipe with one tap.

Settings that matter Light or dark theme. Celsius or Fahrenheit. Sleep hours so the app doesn't ping you at 3 a.m.
