**Empower yourself to find the TRUE best deal.** Ever stood in a supermarket aisle, staring at products with different quantities, wondering which one is actually cheaper? "2,343 yen for 320 sheets x 24 packs" versus "2,726 yen for 400 sheets x 5 boxes x 2 sets" – can you calculate which is better on the spot? When stores display products with varying pack sizes and bundle configurations, intuition alone won't reveal the true best value. "Unit Price Comparator" instantly solves this problem, becoming your essential tool for smart shopping. **■ Key Features** ◆ Precise Comparison Across Any Unit Whether it's "sheets" for tissues, "meters" for toilet paper, or "grams" and "ml" for food items – set the optimal common unit for each product category. No matter how complex the packaging, the app calculates the cost per sheet, per gram, or per meter down to the decimal point. ◆ Smart Input System Our three-tier input method ("Capacity per item × Quantity per pack × Number of sets") makes it easy to register even the most complex products like "320 sheets per box, 24 boxes per case." Total quantity is auto-calculated, preventing input errors. ◆ Auto-Fetch from URLs Simply paste a URL from Amazon or other e-commerce sites, and the app automatically extracts the product name, price, and image. Comparing online and in-store prices has never been easier. The app even parses product titles to extract information like "24 cans" or "350ml," dramatically reducing manual input. ◆ Price Tag Photo Storage Snap photos of in-store price tags and save them with your products. Fine-tune the display position so the price and product name are clearly visible. Perfect for checking "How much was this last time?" later. ◆ One-Tap Tax Calculation Don't worry about tax-exclusive prices. Tap the +8% or +10% tax rate button to instantly convert to tax-inclusive prices. Tax rates can be customized in settings. ◆ Instant Best Deal Identification Sort products in the same category by unit price, and the cheapest item is automatically marked with a "Cheapest" badge. No hesitation – grab the best value option with confidence. ◆ Multilingual Support Supports Japanese and English. Automatically switches based on system settings, with manual language selection available in-app. **■ Perfect For** • Shoppers who struggle to determine which pack offers the best value at supermarkets and drugstores • Anyone who wants to accurately compare online and in-store prices • Smart buyers of complex bundle products (tissues, toilet paper, beverages, etc.) • Budget-conscious individuals serious about household savings • Those who want to manage shopping lists with photos **■ Simple to Use** 1. Create categories (e.g., Tissues, Toilet Paper, Beer) 2. Add products (snap price tags in-store or fetch info from URLs) 3. Enter "Capacity per item," "Quantity per pack," and "Number of sets" 4. Unit price is auto-calculated, and the best deal is instantly clear! **■ Privacy & Data Management** All data is stored locally on your device. Nothing is sent to external servers.
