Common questions

Which fermentation projects can I track?
Sourdough feedings, kombucha brews, sauerkraut, miso, tempeh, koji, kimchi, and pickles — plus custom categories for anything else with a timer.
Does it calculate brine percentage?
Yes. Brine percent by weight, baker's percentage for dough hydration, and salt ratios for lacto ferments. Grams or ounces.
Can I generate HACCP records for commercial food production?
Yes. HACCP-compliant safety plans with temperature tracking — the kind you'd attach to a commercial food production record.
Does Fermento work offline?
Yes. Everything is local. Reminders fire without a network connection.
Is there Apple Watch support?
Not yet. Current version is iPhone and iPad only.
