Sourdough Companion

Bake better sourdough — from your very first starter to your hundredth loaf.
Sourdough Companion is the complete toolkit for home sourdough bakers. No accounts. No cloud. No ads. No data collection. Just you, your dough, and everything you need to perfect your craft.
★ WHY SOURDOUGH COMPANION ★
Most baking apps lock features behind subscriptions, harvest your data, or demand a constant internet connection. Sourdough Companion is different. Every feature works offline. Your photos, recipes, and bake history live on your device — and only your device. One-tap backup means your data is always yours.
★ STEP-BY-STEP STARTER GUIDE ★
Creating a sourdough starter from scratch can feel intimidating. Our 6-day interactive guide walks you through every feeding with clear instructions, visual cues, and progress tracking. Tap to mark each step complete and watch your starter come to life.
★ COMPLETE BAKING WALKTHROUGH ★
From autolyse to the final bake, follow a structured guide covering mixing, stretch and folds, bulk fermentation, shaping, cold proofing, scoring, and oven loading. Every stage includes what to look for so you know exactly when to move on.
★ SMART HYDRATION CALCULATOR ★
Enter your target dough weight and hydration percentage — instantly get precise quantities for flour, water, starter, and salt. Save calculated recipes directly to your collection and load them back anytime.
★ PHOTO BAKE JOURNAL ★
Log every bake with photos, star ratings, hydration, flour type, bulk fermentation time, proof duration, oven temperature, and tasting notes. Over time, your journal becomes your personal sourdough knowledge base — spot patterns, refine techniques, and bake more consistently.
★ STARTER TRACKER ★
Record every feeding with ratio, peak rise, time to peak, ambient temperature, and flour type. Add photos to track activity visually. Understand how your starter behaves across seasons and flour blends.
★ FLOUR REFERENCE LIBRARY ★
Browse a comprehensive flour database with protein content, absorption rates, and blending notes. Know your ingredients before they hit the bowl.
★ MULTI-STAGE BAKE TIMERS ★
Run timers for bulk fermentation, proofing, and baking simultaneously. Audio alerts keep you on schedule even when the app is in the background.
★ KITCHEN UNIT CONVERTER ★
Switch between grams, ounces, millilitres, cups, Celsius, and Fahrenheit instantly. Built for the realities of mixed-unit recipes.
★ RECIPE COLLECTION ★
Save your own recipes alongside built-in defaults. Load any recipe into the calculator, adjust hydration or scale up for a bigger crowd, and save your tweaks. True two-way workflow — not a static list.
★ FULL BACKUP & RESTORE ★
Export everything — journal entries, starter logs, recipes, settings, and every photo — as a single zip file. Restore on any device with one tap. No accounts to manage. No subscription to lose access to your own data.
★ BUILT FOR BAKERS, NOT ADVERTISERS ★
✓ 100% offline — works without internet
✓ No accounts or sign-ups
✓ No ads, ever
✓ No data collection
✓ No cloud — everything stays on your device
✓ One-time purchase, no subscriptions
✓ Photos compressed efficiently using on-device storage
Whether you're a beginner nursing your first starter or an experienced baker chasing the perfect open crumb, Sourdough Companion gives you the tools to bake better and learn faster.
