Fermento tells you when to feed, flip or check every jar, from a sourdough starter to kimchi, kombucha, koji or cured meat, and keeps the pH, salt and weight log as you go. Photograph a surface that looks wrong and get a keep-or-discard call. If you sell what you make, the same log turns into the food-safety plan (HACCP) you'd otherwise pay a consultant for, exported as an inspector-ready PDF.

Hey Product Hunt 👋
I've been fermenting for about a decade, and at some point it got out of hand: I started building my own fermentation rigs and charcuterie fridges, automated curing chambers with temperature controllers and reptile heat mats, and ended up writing an automated version of HACCP, the food-safety system professional kitchens use.
1. Every batch has a plan. Pick what you're making and Fermento walks it through its stages with reminders.
2. Food safety you can follow. HACCP critical limits for cured meat and a PDF export for commercial makers.
3. Cultures with a family tree. Starters, SCOBY hotels and kefir grains keep their lineage.
New on iOS 26+: point the camera at a jar to pull up that batch, ask a question and get the answer from your own notes on the phone, ask Siri what's fermenting, and turn a step like burping the jar into a real alarm.

Do you ferment? If yes, what went wrong in the most spectacular way for you? If no, what would it take for you to start?
