"Shopping Calculator" is a popular calculation app that lets you easily find out which product, A or B, is cheaper, and the post-discount price of products marked with "○ Discount."
------------------
●Over 220,000 downloads! (※) The definitive price comparison app!

●Ranked #2 in "Calculators for Comparing Bargains"!
●This app ranked #2 in "Calculators for Comparing Bargains" on the smartphone app review site "Appliv"! (As of April 23, 2023)
------------------
●3 calculation modes + calculator + shopping list, all in one.
In addition to price comparison, discount calculation, and 100g price calculation functions, it also features a calculator and shopping list.
Easily switch between calculation modes with the press of a button in the footer.
You can quickly operate the app even when you can only operate it with one hand while holding the shopping cart.
●Price Comparison
Compare products A and B to see which is cheaper.
For example, you can quickly determine which is cheaper: 5 boxes of 180 tissues at ¥298 or 5 boxes of 160 tissues at ¥249.
The Premium version also allows you to compare the prices of three products, including product C.
●Discount Calculation
Check the discounted price of products marked with a ◯ discount or ◯% off.
Entering "30% off" on "¥7,980" will display "¥5,586 (¥2,394 off)."
Single-digit discount values are automatically interpreted as "discount," while double-digit values are automatically interpreted as "% off," allowing for quick operation.
●100g Price Calculation
The price per 100g of meat, seafood, etc. may not be displayed. This calculation mode lets you easily find the price per 100g by simply entering the price and weight.
● Lowest Price/Market Price Search
Easily cross-search for the lowest prices on Amazon, Rakuten, and Yahoo! Shopping!
You can also scan the barcode on a product to instantly find the market price.
It also randomly displays items on sale that day. You're sure to find a bargain.
● Calculator
A simple built-in calculator function is included. This is convenient for adding up the prices of items in your cart one by one.
● Shopping List
Write a list of items you want to buy. With the same simple operation as a to-do app, you don't have to open a separate notes app just to view your shopping list.
● One-Handed Design
When holding a shopping cart, it's difficult to use both hands to operate your iPhone. This design makes it convenient to use even in such situations.
● Reduced Tax Rate Support
When displaying the discount amount and price per 100g, the prices for 8% and 10% consumption tax are displayed simultaneously. No need to press a button to switch between tax rates.
