## Description

AI reads your pH curve and tells you if your ferment is safe—or needs attention. Kombucha, kimchi, cheese, hot sauce, and more.

Ferment Lab is the batch tracker home fermenters have needed for years. Log every jar, vessel, and crock — with pH readings, photos, tasting notes, and scheduled check-ins — and let on-device AI tell you if your ferment is on track.

AI pH Safety Advisor
Log your pH readings as your batch develops. Ferment Lab analyzes your acidification curve against culture-specific safety profiles (kimchi, kombucha, brine pickles, and cheese all behave differently) and tells you: on track, watch it, or discard. No guessing. No forum searching at midnight.

Built for every ferment except bread
Kimchi. Kombucha. Kefir. Hard and soft cheese. Hot sauce. Pickles. Sauerkraut. Vinegar. Miso. Tempeh. Wine and cider. Each culture gets the right schedule, right safety thresholds, and right guidance. Sourdough? That's Crumb — a separate app for bread bakers.

What you track
Salt %, temperature, vessel size, pH readings over time, tasting ratings, and a full photo journal. The batch detail screen is the most organized fermentation log you've ever had.

Designed for the counter
Live Activities keep your next check-in on your lock screen. Widgets show all active batches at a glance. Siri shortcuts log a pH reading without unlocking your phone.

All data stays on your device or syncs privately via iCloud. No accounts. No server.
