## What is Sourdough Timer Pro?

NEW: FULL BAKE PLANNER

Plan the whole bake, from feeding your starter to taking the bread out of the oven.

• 14 tested recipes: country loaf, challah, pitas, pizza, focaccia and more, with every ingredient in grams for the amount you choose
• Tell the app when you want the bread ready and it calculates when each step starts. You can also plan days ahead, starting from the starter feed
• A reminder for every step, including each fold, even when the app is closed
• Choose how you bake: Dutch oven, baking stone or steel with steam, or a loaf tin. Times and temperatures adapt to your method
• Oven timers: tap "I put it in the oven" and the app counts down every stage (lid off, drying and more). Every timer is editable
• Guided path to build a sourdough starter from scratch, with daily reminders
• In-app feedback form
• English and Hebrew
• No ads

STARTER CALCULATOR

Sourdough Timer Pro computes the exact feeding schedule for your sourdough starter, working backward from your target ready time to give you a precise feed time and gram-level recipe.

HOW IT WORKS

Enter six parameters: target ready time, quantity of starter needed (grams), desired hydration percentage, flour type, starter activity level (%), and ambient temperature (°C or °F). The app applies a fermentation kinetics model that factors temperature-dependent metabolic rates of lactic acid bacteria and wild yeast to calculate when your starter will hit peak activity.

OUTPUT — YOUR FEEDING PLAN

• Feed time: the exact moment to feed so your starter peaks on schedule
• Starter / flour / water quantities in grams
• Feed ratio (e.g., 1:9.8:9.8)
• Estimated peak pH
• Predicted flavor profile (mild, balanced, tangy, complex)
• Recommended bread types suited to the resulting starter profile
• Fermentation timeline chart with 80% activity window marked

Set process alarms directly from the results screen to get notified at feed time and at peak.

DESIGNED FOR PRECISION

Temperature has a nonlinear effect on fermentation speed. A 5°C difference between summer and winter kitchens can shift peak time by 2–4 hours. Sourdough Timer Pro accounts for this so your timing stays consistent regardless of ambient conditions.

Supports both Celsius and Fahrenheit. Works across all flour types including whole wheat, rye, spelt, and einkorn. Starter activity input lets you calibrate for your specific culture's behavior.

PROFESSIONAL & HOME BAKERS

Built for bakers who want repeatability and data-driven control over their sourdough process. Used by professional bakery instructors for workshop demonstrations and planning.
