Ferment: Fermentation Tracker

Ferment without the guesswork. Track your batches, calculate your salt, and know exactly what's happening inside your jar — from day one to first taste.

Fermentation is 20% doing and 80% worrying. Is that white stuff mold? Did I add enough salt? Is it safe to eat? Ferment is the companion app that replaces panic with confidence.

NOT A RECIPE BOOK. NOT A TIMER. The app that tells you "this is normal," calculates your salt, reminds you to check your jar, and helps you understand what's happening inside it.

WHAT'S INSIDE

Visual Health Checker — "Something Look Weird?" See white film, fuzzy spots, soft vegetables, or cloudy brine? Our symptom-based guide walks you through what you're seeing with photo references for every common issue. Clear verdicts: safe, take action, or discard.

Salt & Brine Calculator End the "percentage of what?" confusion forever. Two modes — dry salt for shredded vegetables, brine for whole vegetables. Per-vegetable recommendations, salt type converter, and jar-size presets.

Batch Tracker with Smart Reminders Track up to 10 active ferments with type-specific timelines. Not countdowns — flavor evolution guides that tell you what to expect at each stage. Smart notifications remind you to check submersion, burp jars, and taste test at the right moments.

Batch Journal Log tasting notes, rate sourness and crunch, and track your fermentation journey from day one. Duplicate successful batches to make them again with one tap.

15+ Opinionated Recipes One tested, confident recipe per ferment type. Sauerkraut, kimchi, dill pickles, hot sauce, curtido, fermented carrots, and more. Each with a "what could go wrong" section addressing real issues from the fermentation community. Tap "Start Batch" to create a journal entry with reminders in one step.

Safety & Confidence Center Science-backed answers to every beginner fear. Why lacto-fermentation is inherently safe. Why botulism isn't a real risk in salted vegetable ferments. How to trust your senses. A per-batch safety checklist so you never have to wonder.

DESIGNED FOR BEGINNERS If you've been staring at your first jar of sauerkraut wondering if something has gone terribly wrong — this app is for you. Warm, confident guidance from a knowledgeable friend, not a textbook.
