## What is FermentLog?

FermentLog keeps culture care and every batch history in one private place.

- reusable cultures and local reminders;
- batch checks, target dates, status, and recipe checklist;
- temperature, pH, gravity, sensory notes, and photos;
- 8 offline plans with visible sources, favorites, and quick repeat;
- brine, hydration, and estimated ABV calculators;
- searchable history, insights, JSON backup restore, and CSV export;
- no account, ads, analytics SDKs, or developer data collection.

Sourdough, kombucha, and milk kefir are free with unlimited entries. FermentLog Pro unlocks all fermentation types and advanced insights.

FermentLog is a journal, not a laboratory safety test. Always follow current research-based recipes.
