栄養計算&節約献立 - 栄養バランスと食費節約を両立

In today's world of rising prices, this app was created to address the daily dilemma of wanting to reduce food costs while still ensuring adequate nutrition.

Aiming to balance nutritional calculations with realistic meal cost calculations, this tool was built from the developer's own desire to create efficient meal plans that meet nutritional requirements while keeping food costs down.

(When the developer tested this app, a meal plan costing approximately 700 yen per day while maintaining nutritional balance was found. Please try creating even more efficient and budget-friendly meal plans!)

【App Overview】

This app is intended for the following uses:

● Creating meal plans using all supermarket sale items
Simply buy seasonal sale items and create meal plans using them each time.

Manual input is possible, but it's also possible to let the AI ​​handle automatic creation.

You can choose to have missing ingredients automatically purchased, or to manage entirely with the specified ingredients you already have on hand.

● Saving Favorite Menus
Save your "family staples" and "tried-and-true budget-friendly menus" (not limited by season) within the app so you can recall and reuse them anytime.

● Executing Menus
This is a specialized function for actually "cooking and shopping" based on the menus you've created.
You can easily check shopping lists and cooking instructions for today's recipes, thoroughly preventing forgotten items and cooking errors.

Pattern A: [Shopping → Menu] Buy inexpensive items at the supermarket, then the app automatically generates a menu.

Pattern B: [Menu → Shopping] Determine a menu based on your budget using the app, then go shopping.

These two patterns are envisioned.

【App Features】

This app includes the following features to balance household budgeting and nutritional management:

● AI-Assisted Menu and Recipe Generation
Refrigerator-Based Menu: Specify the ingredients you have on hand (sale items, etc.), and the AI ​​automatically creates a menu that "uses them all up."

Customizable Criteria: You can specify criteria such as "low-salt (salt target)," "cuisine genre (Japanese, Western, etc.)," ​​and "today's mood" to have the AI ​​suggest recipes.

Persona (Target Audience) Setting: The system automatically calculates appropriate portion sizes (multipliers) based on the age of the target group, from infants to adults.

High-Precision Real-Time Nutritional Analysis:

Based on Public Databases: The system precisely calculates nutritional deficiencies and excesses by 100% referencing the following highly reliable data established by the government:

Standard Tables of Food Composition in Japan (8th Revised Edition), Enlarged 2023

Dietary Reference Intakes for Japanese (2020 Edition)

Supplementary/Deficit Graph: Visually displays the percentage of your current meal relative to your daily target. Reverse lookup of ingredients (within your "My Ingredients") that contain high amounts of deficient nutrients is also possible.

Smart Combined Shopping List:

Automatic Calculation of Household Total Weight: The system automatically combines the same ingredients used in multiple days' menus or different dishes, displaying the "Total Household Weight to Buy Today." Daily Inventory Coverage Management: Visually manage whether you have stocked ingredients for a specific date, such as "I bought one head of cabbage, so I have enough for today and tomorrow."

● Blazing Fast Master Data Update (Price & Unit Synchronization)
Direct Input of Purchased Quantity: Simply enter "I bought 300g for 180 yen," and the system automatically calculates the exact cost of the 50g portion used in recipes.

All Data Reflected at Once: Prices updated here are instantly reflected in all recipes and ongoing menus using that ingredient, keeping your household budget simulation always up-to-date.

● Automatic Serving Size & Multiplier Scaling
One-Tap Serving Size Change: Changing the serving size on the cooking screen instantly updates the recipe ingredients and shopping list quantities to match the number of servings (automatic conversion of quantities, such as 150g = approximately 1.2 pieces).

● No Registration Required & Secure Data Design
Instant Use: No troublesome account registration or personal information input required. Ready to use immediately. Snapshot saving: Menu data is saved in the state it was in when it was created, so even if you rewrite the master data later, past data will not be corrupted.
