About

FermentAdvisor

Read full description

FermentAdvisor is a tracker for your live ferments — not a recipe app. Start a jar for whatever you're fermenting — kombucha, kimchi, sauerkraut, pickles, vinegar, miso, water kefir, milk kefir, yogurt, sourdough starter, fermented hot sauce, or tepache — and FermentAdvisor keeps a running schedule for it: when to check, when to feed a culture, when it's likely done. PLAN a ferment: pick what you're making, and get a real timeline built from how that ferment actually behaves — not a generic countdown. The app reminds you along the way: a starter that needs feeding, a batch that's ready to check, a culture that's gone quiet. You don't have to remember any of it. CHECK in when a reminder fires, with a photo if you want a closer read. FermentAdvisor tells you what it's seeing and what to do next. LOG the result when a batch is done — what worked, what to change next time — so every ferment makes the next one better. FermentAdvisor covers the whole loop for perpetual cultures too: sourdough starters, kombucha SCOBYs, kefir grains, and vinegar mothers all get their own feed-and-maintain schedule, not just one-off batches.
