The Calculator App Neumorphism

The Calculator
The "The Calculator" app can be enjoyed not only with the functions of the calculator, but also with the design using neumorphism!
There are many calculator apps out there, but many have similar designs.
So, with this app, we challenged a new design that incorporates neumorphism!
Also, you can change the background color and text color!
New designs have been added to the existing calculator apps, and there are more elements to enjoy.
I tried to reproduce the realistic feeling including the feeling when pressing.
Supported functions
・"÷" "×" "+" "-" arithmetic function
・Supports "%" and "00"
・Operation after the decimal point "."
