This app is meant to facilitate your life!
Calculate a discount percentage, deduct some tax or simply find out the value of a percentage at your fingertips in 3 clicks!

In the main screen there are 3 buttons, each characterized by its own color, which subdivide the app into three sections.

1. Calculate the percentage of a number
2. Calculate the percentage increase
3. Calculate the percentage decrease

Each mode allows you to calculate the customized percentage, filling in two simple fields (value and percentage) finalized all with a simple "calculate" button.

In the case of typing errors or simply multiple calculations, the "C" key is present which cleans up all the cells, allowing them to be used again.
