Sourdough Planner

Bulk Planner helps sourdough bakers plan a loaf from bake time backward.

Choose when you want to bake, then build a schedule for mixing, autolyse, stretch and folds, preshape, final shape, cold proof, and bake time. The app combines formula math, dough temperature guidance, fridge-aware cold proof planning, and native iPhone reminders so your bake day feels easier to manage.

Features:
• Reverse-plan from your target bake time
• Calculate flour, water, salt, and 100% hydration starter
• Save and load favorite dough formulas
• Get suggested water temperature for your target dough temp
• Plan autolyse, folds, preshape, final shape, cold proof, and bake alerts
• Adjust timing for room temperature, dough temperature, fridge temperature, grain mix, starter condition, and banneton type
• Use Lock Screen and Dynamic Island Live Activities for active schedules
• Mirror iPhone notifications to Apple Watch
• Log starter peaks and bake results so the app can tune future estimates
• Keep notes for each bake

Bulk Planner stores formulas, notes, timers, and learning logs locally on your device. No account, ads, analytics, or tracking.

Sourdough is alive, so timing will always vary. Bulk Planner gives you a smarter plan, while the dough’s look and feel remain the final signal.
