Ferment & Sprout

Ferment&Sprout keeps track of the living projects in your kitchen: ferments, starters, sprouts and microgreens. Each one has its own timer and rhythm, so you can see at a glance what's on track and what needs a look. BATCHES • Timers for kombucha, sauerkraut, kimchi, pickles, hot sauce, kefir, ginger beer and more • Day counts, time left, and a clear "Check it" when a batch reaches its target time • Guided checks from built-in recipes, such as when to start tasting • A check-in log for notes on how each batch is doing • Optional reminders, set per batch STARTERS • Care rhythms for sourdough, ginger bug, milk and water kefir, kombucha SCOBY, vinegar mother and more • Feeding history and status at a glance • In the Fridge: rest a starter with a weekly or every-2-weeks check instead of daily reminders • Built-In Templates: start from a trusted setup and adjust it before saving SPROUTS & MICROGREENS • Soak, rinse, blackout and light stages with a harvest window • Rinse reminders every 12 hours • A care log of every soak, rinse and move to light OPTIONAL AI COMPANION Ask questions about a batch, starter or sprout, and save useful parts of an answer to your notes or recipe. It uses Google Gemini with your own API key. Nothing is sent until you add a key and accept the notice, and you can turn it off in Settings. AI answers can be wrong and can't confirm whether food is safe. PRIVATE BY DESIGN • No account, no ads, no analytics, no tracking • Everything is stored on your iPhone. The only thing that leaves it is what you send to the AI Companion, if you use it. • Export a backup file whenever you like Ferment&Sprout gives guidance, not guarantees. Always check your ferments yourself, and when in doubt, throw it out.
