## What is Sourdough Tracker?

Your sourdough starter is alive — Boulie makes sure you both thrive.

Meet the app that turns starter care from guesswork into a relationship. Name your starter, feed it, scan the jar, and Boulie tells you the exact moment to bake. No more "is it ready? did I kill it?"

KNOW WHEN TO BAKE
• Rise checks read your jar and confirm the peak — bake in the window, every time
• A live prediction engine learns your starter's rhythm from feeds, ratios, and kitchen temperature
• "Peaks in ~4 h" right on the home screen — plan your bake day with confidence

A STARTER WITH A HEARTBEAT
• Your starter has moods: sleepy, rising, peaked, hungry (never guilt, always charm)
• Mode-aware care: daily feeds on the counter, weekly in the fridge
• Feed reminders arrive when your starter actually needs them — no spam

BAKE WITH A GUIDE
• 100+ step-by-step recipes, from country loaves to focaccia, bagels, and pizza
• Guided bake mode with real alarms that ring through silent mode (iOS 26)
• Hydration calculator with baker's percentages, done right

REMEMBER EVERY LOAF
• A photo-first bake journal — every loaf, rating, and crumb note in one shelf
• Rise trends show your starter getting stronger week over week
• Share cards for the loaves (and the milestones) worth bragging about

PRIVATE BY DESIGN
Your data and photos stay on your phone. No account. No tracking.

Boulie Pro unlocks unlimited rise checks, smart reminders, and the full journal. Subscriptions renew automatically; cancel anytime in your App Store settings.
