About this app
A simple and convenient free unit price comparison calculator app that calculates the unit price from the entered price and quantity. You can compare not only two but six at the same time. There is no limit on the number of digits when entering the price and quantity. The price and quantity can be entered not only by numbers but also by formulas, and the unit price can be calculated by reflecting the shipping fee, service fee, increase in the number of items, and discount coupons in the price including tax. Save the unit price calculation result in a history memo and compare the unit prices to save money. Share history on SNS.
