## What is Jarvyn?

Jarvyn is a personal home-fermentation journal for tracking active batches, recipes, pantry stock, and tasting notes.

WHAT YOU CAN DO

• Board — Kanban columns for Planning, Fermenting, and Ready to Taste. Search, filter, calendar view, archive batches, and log observations with photos, scores, temperature, and voice notes.
• Recipes — Built-in templates plus custom recipes. Start a batch from any recipe with one tap.
• Pantry — Track ingredients, quantities, low-stock alerts, and expiry dates.
• Tools — Projects, archived batches, shopping list, tasting history, monthly report, recipe favorites, recipe slots, and ferment guide.
• Me menu — Open from the profile icon on any tab: coin balance, coin store, batch reminders, app settings, privacy policy, support, and clear-all-data.

COINS & EXTRAS

New users receive welcome Jar Coins to try premium exports. Spend credits on optional observation log PDFs, HD batch labels, recipe card exports, monthly reports, extra recipe slots, and premium label styles. Purchase additional coin packs in the Me menu when you need more. Coin packs are consumable in-app purchases with no subscription.

REMINDERS (OPTIONAL)

Turn on batch reminders, weekly digest, and per-batch Notify Me alerts from Batch Reminders in the Me menu or batch detail. Choose dates, lead days, and notification times. Reminders stay off until you enable them and allow permission in iOS Settings.

DESIGNED FOR HOME FERMENTERS

Warm, calm interface with four focused tabs and practical tools for kimchi, kombucha, sourdough, pickles, and more—not social feeds or marketplace listings.

Open the app, explore sample batches on first launch, or tap + on the Board to start your first ferment.
