うちかご-家族で買い物・在庫共有

This is a shopping and inventory management app that the whole family can use.

When inventory runs low, items are automatically added to your shopping list. Checking off a purchase returns it to your inventory. Uchikago automatically handles the recording and input process.

Share "what to buy" and "what you have at home" in real time with your family, spouse, or roommates. Even if someone adds or purchases an item, it's immediately reflected on everyone's screen, preventing misunderstandings like "Did you buy that?" and preventing duplicate purchases.

■ Inventory and shopping list are automatically linked (Uchikago's main feature)

- When inventory falls below the minimum quantity, it's automatically added to the shopping list (shortage alert). Eliminates the hassle of "writing a memo after running out"
- When adding to your shopping list, it suggests items from your inventory for quick input.
- Items checked as purchased are reflected in inventory with a single tap.
- The purchase date, time, and person who made the purchase are also recorded, so you can see at a glance "when and who bought it."

■ Reduce food waste with lot-unit expiration date management (FEFO)
- Even for the same product, each arrival/addition is managed as a lot with "quantity + expiration date + addition date."
- When the quantity is reduced, it automatically consumes from the lot with the closest expiration date (FEFO = First In, First Out). Prevents "food items that were in the back expiring before you realize it."
- Expired and near-expired items are color-coded on the screen when you open the app. It also supports sorting by "closest expiration date."
- Used-up and discarded items are recorded as inventory history.

■ Shopping List
- Add/edit/delete items with name, quantity, unit, category, and memo.
- Filter by category to display only unpurchased items. Efficient shopping is possible in each section of the store.
- Family edits are reflected in real time, so you can always see the latest information at the checkout.

■ Inventory (Pantry) Management
- Manage quantity, minimum quantity, and expiration date all in one place.
- Automatic addition can be toggled on/off for each item.

■ Connecting Menus, Inventory, and Shopping with Recipes
- Register frequently made dishes as "Recipes." You can save ingredients (name, quantity), cooking steps, notes, and serving size.
- Each ingredient can be linked to an inventory item. When you tap "Made," the inventory for the amount used decreases all at once and is recorded in the consumption history (it stops at 0 and notifies you if the inventory is insufficient).
- Add ingredients to the shopping list from the recipe. You can select only the necessary ingredients by checking them, and those already on the list are automatically skipped.
- Specifying "Serving Size" increases or decreases the amount of inventory consumed and the number of items added to the shopping list according to the number of people.
- Entering an ingredient name will suggest items from the inventory. "Automatically link with inventory" allows you to link ingredients with matching names all at once.
- When the recipe is empty, you can add sample recipes (meat and potato stew, stir-fried vegetables, miso soup) with one tap.

■ Categories
- Organize categories with icons.
- Set a default expiration date for each category, and the expiration date will be automatically set when inventory is added.
- Optimize to suit the flow of movement in the store or kitchen with sorting.

■ Real-time sharing with family and groups
- Add members with an invitation link (valid for 7 days). There is no need to share account information.
- Share permissions according to use, such as family, work, or clubs, with owner/editor/viewer roles.
- Switch between multiple groups. Use categories like "For Home" and "For Parents' House" to differentiate items.
