About

ShoppingCalculator byNSDev

Features
Read full description

This app was created to easily calculate discount items when shopping. You can calculate immediately with fixed value buttons such as 5%, 10%, 20%, 30%, 40%, 50% 60%. Other than that, I made it possible to select from 1% -99% selection screen. You can subtract it from the total amount with the + - buttons on the left and right of the amount. History can be displayed. When you enter a budget, we automatically calculate the balance that can be purchased. Use the AC button to make it all 0s and history is cleared. The C button sets the current item's amount to 0. The BS button deletes the current amount by one digit. The currency is the Japanese yen. Please fill out the request in the review. We will correspond as much as possible.
