Stash Bag

StashBag Turn the “spatial storage bag” from cultivation novels into your everyday tool.

In cultivation fantasy stories, the protagonist always carries a spatial storage bag—open it, and every resource and artifact is clearly visible. StashBag brings this idea into real life, helping you keep track of what you truly own. No more forgetting, no more duplicate purchases, no more expired items.

Core Features

1. Consumables Management Perfect for plumbing parts, household supplies, and daily essentials. Set safety stock levels and automatically add low-stock items to your shopping list. Quick +/− quantity adjustment, expiration reminders, and usage tracking. Avoid realizing you’ve run out right when you need something.

2. Collectibles Management (LEGO Supported) Ideal for LEGO, figures, and models. Manage Owned and Wishlist items with automatic shopping list integration. Search by LEGO set number to import official name, image, and piece count. LEGO data is provided via the Rebrickable API (https://rebrickable.com/). This app uses Rebrickable’s public API.

3. Smart Shopping List When consumables fall below safety stock or collectibles are marked as Wishlist, they are automatically added to your shopping list. See everything at a glance when you shop.

4. Local-First Design All data is stored on your device. Supports JSON export and import for backup. Available in Traditional Chinese, English, and Japanese, with dark mode support.

StashBag is your digital storage bag—so you always know what you own and when to restock.
