FermentLog: Fermentation Log

Never miss a feeding or lose the details behind a successful ferment. Track cultures, batches, reminders, photos, pH, temperature, and outcomes—fully offline.

Never miss a feeding. Never lose the details behind a batch that worked.

FermentLog is a private, offline fermentation journal that turns daily notes into repeatable results—without an account, ads, or tracking.

CARE FOR YOUR CULTURES

• Save reusable sourdough, kombucha, kefir, and other cultures • Get private local reminders for feedings and care • Tap a reminder to open the right culture or batch • Keep photos and notes together instead of scattered across apps

RUN BETTER BATCHES

• Follow checks, target dates, status, and recipe steps • Record temperature, pH, gravity, sensory notes, and photos • Use brine, hydration, and estimated ABV calculators • Start from eight offline plans with visible sources, favorites, and quick repeat • Save one custom template free; Pro removes the template limit

LEARN FROM YOUR HISTORY

Rate completed batches, record whether you would repeat them, compare outcomes, and spot patterns in Insights. Export a spreadsheet-friendly CSV or create a restorable JSON backup whenever you want.

Sourdough, kombucha, and milk kefir are free with unlimited entries. FermentLog Pro unlocks all 14 fermentation types, unlimited custom templates, batch comparison, and advanced outcome insights. Choose annual access with an eligible 7-day trial or a one-time lifetime purchase.

PRIVATE AND OFFLINE

No account, ads, analytics SDKs, or developer data collection. Your journal stays on your device.

FermentLog is a journal, not a laboratory safety test. Always follow current research-based recipes and discard anything you believe may be unsafe.
