Point your phone at the jar: Boulie reads the rise and tells you when your starter peaks. Smart feed reminders, 100+ guided recipes and a photo bake journal.
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
