Full support for unit price and discount calculations By entering the price and quantity of a product, you can automatically calculate unit prices such as per item, per 100g, or per 1ml. Additionally, by entering a percentage off or a discount amount, you can instantly calculate the price after the discount. You can judge questions like "Is it really cheaper even with a discount?" or "Is buying in bulk a better deal?" with accurate numbers, not just intuition. Supports multiple currencies To accommodate international online shopping, imported goods, and purchases made while traveling, multiple currencies are available. Simply by switching currencies, you can compare prices with the same familiarity, allowing for worry-free use both domestically and internationally. Comparison history is automatically saved Price comparisons that have been calculated are saved as history and can be reviewed at any time. You can quickly check information such as "Which did I choose last time?" or "What was the price before?", enabling continuous smart purchasing decisions.
