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.
