Fermento: Sourdough Tracker

Your sourdough starter is alive. Fermento treats it that way.

Klaus — or whatever you name yours — has a face. Leave him too long and he looks hungry. Feed him and he beams. It sounds silly right up until you realise you haven't killed a starter in months.

SIX JARS, ONE SHELF
Sourdough starter, brine pickles, kombucha, kraut and kimchi, yogurt and kefir, ginger bug. Each one gets its own character, its own rhythm and its own checklist.

REMINDERS THAT READ THE ROOM
Free jars run on a fixed rhythm you choose. With Plus, tell Fermento how warm your kitchen is and it shortens the gap between feeds on hot days, stretches it when it's cold. Quiet hours are respected — nothing pings you at 3 a.m. Burp reminders for pickles, fizz checks for kombucha, wake-up reminders when a jar comes out of the fridge.

FEED BY THE SCALE
Tell Fermento once what the empty jar weighs and every feed names the number to watch for instead of an amount to guess at. Your jar can hold a blend — 70 % wheat, 30 % wholegrain rye — and Bubbie says whether that ratio carries it to the next feed.

WHEN SOMETHING LOOKS WRONG
Grey liquid on top? White film? No rise? Pick what you see and Bubbie explains what it actually is. With Plus it then installs a real fix on the jar: a changed ratio, a shorter schedule, a set number of feeds. The jar stays in rescue mode until it's back on track.

IT LEARNS YOUR STARTER
Log a rise and Fermento remembers how long it took. After a handful of logs it stops guessing and tells you when your starter will peak — with a countdown on the lock screen so you catch the window instead of missing it.

PLAN A BAKE BACKWARDS
Say when the dough goes together and Fermento names the feed time and the ratio so the starter peaks exactly then. One plan a month is free.

EVERYTHING YOU DID, KEPT
A calendar that fills itself and, with Plus, a photo timeline per jar and a monthly recap you can share. Dough and brine calculators. Bake-day timers. Discard recipes so nothing goes in the bin.

BADGES YOU EARN
Thirteen milestones and sixteen outfits for your jars. None of them can be bought — they only come from actually looking after your ferments.

NO ACCOUNT, NO TRACKING
Everything lives on your iPhone. Sync across your devices with your own iCloud if you want it. No sign-up, no ads, no analytics, nothing sold on. The weather heads-up is optional and only ever sends a rounded-off region, never an address.

FERMENTO PLUS
Free keeps two jars and 30 days of history.

Fermento is a logbook, not a lab. It won't tell you whether something is safe to eat - when in doubt, throw it out.
