Tired of writing or typing the same items over and over when making shopping lists? Shopping Supporter saves everything you've entered before, so you can easily add items again from your history. Once you add an item to your Shopping List, a simple swipe moves it to your Inventory—no need to retype purchased items. Similarly, when something runs out in your Inventory, just swipe to move it back to your Shopping List. For staples like beverages and breakfast items, register them once and simply move them between Inventory and Shopping List—no repeated typing required. Shopping Supporter goes beyond inventory management with Recipe List features for managing recipes and recording your daily meals. The app integrates with your Inventory and Shopping List, so you can see at a glance whether recipe ingredients are in stock or need purchasing—just check the icon status. Tap icons to add items to lists or remove them. As you register ingredients for dishes you want to cook, you'll instantly see what you have and what you need to buy. Missing items can be added to your Shopping List with a single tap. The Recipe Calendar lets you record dishes you've cooked each day. Plan ahead by deciding what to cook and identifying what to buy, or look back to ensure you're not repeating similar meals too often. Additional Features: ■ Group Management Create unlimited groups like "Vegetables," "Beverages," "Seasonings," and "Household Items." Customize display order—we recommend organizing groups by shopping order (produce section, meat counter, fish counter, etc.). Assign custom colors to each group for easy visual organization. ■ Adding Items Record name, group, icon, quantity, unit, price, purchase date, expiration date, URL, and notes. Quantity accepts both numbers and text, so you can use descriptions like "a little left" or "plenty" for items that are hard to quantify. Units can be customized and reordered just like groups. ■ Best & Worst Prices When you enter prices, the app tracks the lowest and highest prices for each item. If quantity and unit are specified, it displays unit price (e.g., price per gram). Perfect for comparing prices while shopping. ■ Smart Suggestions When adding to Inventory or Shopping List, the app displays matching items based on what you type.
