Devalluator Calculation Tool

Devalluator is a neat little app designed to make calculating percentages fast and simple.

It uses large buttons to input values and hot keys to let you select the percentage you want to apply to a figure.

Ideal for shopping environments when you just want to quickly find out the discount on that special pair of shoes and not wast time fiddling about with small buttons and complicated functions.

The app can perform 5 percentage functions:

-Percentage off a value
-Percentage of a value
-Percentage on a value
-Original price before percentage was increased
-Original price before percentage was reduced
