Free: the full recipe library (59 recipes), up to 3 active ferments, 2 cultures and 2 recipes of your own, check-ins, reminders, the mould and kahm guide, widgets, jar labels, story cards and timelapses. Paid Crock Pro subscription required for unlimited ferments, cultures and recipes, AI photo checks (3 free to try), Insights charts, batch comparisons and Lock Screen countdowns. Crock turns your fermentation shelf into something alive. Every batch is drawn as its own printed jar: the brine clouds as it sours, bubbles rise faster in a warm kitchen, and kombucha bottles fizz until you burp them. KNOW WHAT EVERY JAR NEEDS TODAY - Your shelf shows each batch with what it needs next: burp, taste, check or move to the fridge - Timelines adjust to your room temperature, so you know when a kraut at 18 C will actually be ready - Ready by Saturday? Pick the day and Crock tells you when to start - Bottle in flavours: split a kombucha or kefir first ferment into several flavoured bottles, each tracked - A jars and gear list that shows which jars are free - Reminders at sensible hours, quiet hours, or mute a single jar A LIBRARY THAT WALKS YOU THROUGH IT - 59 recipes: sauerkraut, kimchi, dill pickles, hot sauces, salsa, preserved lemons, garlic honey, ketchup and mustard, kombucha, jun, kefir, ginger bug sodas, tepache, kvass, yogurt, tempeh, natto, shio koji, miso, gochujang, nukazuke, idli and dosa batter, injera, sourdough bread and starter, and vinegar - What's in season this month, and long cold ferments like kimchi-fridge kimchi at 2 C - Scale any recipe and Crock recalculates the salt by weight, plus a salt and brine calculator in grams or spoons - Bake planner: baker's percentages in grams, and when to start so your bread is ready on time, with reminders - Write your own recipes, or save the batch that turned out perfect - Share or print any recipe as a PDF, or make a shopping list from it IS THIS OKAY? - Illustrated guide to what is normal, what is harmless (kahm yeast) and what means throw it out (fuzzy or coloured mould) - A step-by-step check that rules out the risky cases first - AI photo check: snap the surface for a second opinion on kahm versus mould (Pro, 3 free checks) - pH guidance around the 4.6 line for hot sauces and salsas CULTURES THAT LIVE FOR YEARS - Sourdough starters, kefir grains, SCOBY hotels, continuous-brew kombucha, ginger bugs and nuka beds - Feeding schedules for counter or fridge, streaks, and a growth chart when you weigh kefir grains - Link each batch to the starter, SCOBY or grains it was made with - Split a culture to gift it and Crock remembers its family tree SEE WHAT MAKES A GOOD BATCH - pH and temperature charts for every batch - Insights across all your ferments, and any two batches side by side (Pro) - Turn a batch's photos into a timelapse video to share MADE FOR IPHONE - Widgets with Burped and Fed buttons, right on your Home Screen - Lock Screen and Dynamic Island countdowns (Pro) - Siri and Shortcuts: "What needs me?", burp a batch, feed a starter - Follow a HomeKit temperature sensor - Jar labels with QR codes, story cards, iCloud sync, metric and imperial - Back up everything to one file and restore it any time - In English, German, Polish, Japanese, Spanish, Portuguese and French Crock never tells you food is safe to eat. When something looks wrong, it helps you decide, and when in doubt, it says throw it out.
