About this app

This is a convenient automatic calculation app that lets you see at a glance how much change you will get when you pay in 1,000 yen, 5,000 yen, 10,000 yen, etc., just by entering the price.

Then, multiple payment patterns and change are instantly displayed so that you can respond immediately no matter what bill or coin you pay with, such as "20 yen change if you pay with 1,300 yen," "220 yen change if you pay with 1,500 yen," "720 yen change if you pay with 2,000 yen," "3,720 yen change if you pay with 5,000 yen," and "8,720 yen change if you pay with 10,000 yen."
