## What is Ferment Tracker?

Free: up to 3 active ferments, 10 recipes, 10 completed batches, 3 photos per batch, salt calculator, and reference guide. Paid Crock Pro subscription required for unlimited tracking/history/photos, AI guidance, PDF export, and custom icons.

Crock is the fermentation companion built for makers who care about craft. Track every batch from the first salt rub to the final taste test. Log check-ins, monitor pH and temperature, capture photos, and build a recipe journal that grows with your skills.

Whether you are fermenting sauerkraut in a ceramic crock, brewing a continuous kombucha, culturing water kefir, making kimchi by the jar, aging miso, lacto-fermenting hot sauce, or pickling crisp seasonal vegetables - Crock keeps every batch organized and on schedule.

TRACK EVERY FERMENT

Start a new batch in seconds. Set your vessel size, salt percentage, and target ferment time. Crock shows each active ferment on a clear dashboard with a color-coded status: bubbling away, ready to check, or finished and ready to eat.

- Active ferment dashboard with day count and status at a glance
- Check-in log with taste notes, pH reading, temperature, and aroma
- Photo documentation at every stage
- Salt percentage calculator built in
- Seasonal fermentation calendar to know what to make and when
- Filter and sort batches by type, status, or creation date

BUILD YOUR RECIPE JOURNAL

Stop losing your best batches to scribbled notes. Crock gives every recipe a proper home: ingredients, method, salt ratios, and your personal notes all in one place. Rate your results and refine over time.

- Structured recipe entries with ingredient lists and method steps
- Salt percentage and brine ratio fields for precision
- Star ratings to track your best batches
- Search and filter by ferment type
